Title: Post Chronos 2.1 clips here!
Post by: marcus on February 10, 2020, 05:16:30 AM
Hey I'm awaiting my Chronos 2.1 and I've already seen a few posts showing clips using the camera!

I think it would be cool to make this the place to post clips so we have a main thread instead of them being scattered around.

Here are some from other users I saw to start the ball rolling:
Photopage: (Flying Moth 1,000fps 1080p) https://youtu.be/ytQchDACNkE
Preftech: (Water tap 1,000fps 1080p) https://www.youtube.com/watch?v=T0FSl5ORMEM

Look forward to seeing more! :)

Here is some tests that I made today https://youtu.be/uJkoIlmD5V0

Seems that I missed the focus on last one slightly. The larger sensor and a fast lens that is sharp even wide open make focusing bit more demanding but I think I am going to get used to really making sure that it's spot on. But other than that I think the picture looks really good already. The first shot was really demanding since it was really dark and we were still shooting 1000fps.

Thanks for the Post!I think this is the fist time that i have ever seen an inofficial unlistet Video of a big channel with this little views ;)
Focus is a bit to close towards the Camera on the Second clip, but when the Little Bits of the Cards get into focus, when they fly, it is very sharp there.
This setup can really produce nice Shallow depth of field!Also again, the colors look pretty good!.
You can always Close the Iris (apperture) of the Lens a bit, if you want a larger Depth of field. But if it is allready very dark, as in this case, that is propably not an option....

Looks really great and sharp. Though it almost looks like it was shot in 500fps and slowed down to look like 1,000, is that because of the motion blur?

I'm still a lens noob but is that motion blur effect caused by the F4 aperture or the 357 degree shutter?

That is just the (basically almost full) 360 degree Shutter, that makes everything look like that.
That is also the Reason, why the common reccomendation is to use 180 degree shutter. This gives some amount of motion blur, but not too much, also 180 degree Shutter was used in Cinema Movies for a very long time, so we are very much used to the look of it.
If you go far below 180 degree, like, lets say 18 degree, your individual Frames will look Sharper, but the clip istself wont look as Smooth. For Pans or Fast Camera Movements, also anything in The Frame that moves Quickly will Look choppy. This is often used in Action Scenes or other Very fast Scenes to make it look more intense or harsh (maybe not alway as extreme as 18 degree, maybe more like 90 or so).
If you go way above 180 degree, like here 360 degree, everything just blurs together and it also looks odd. Thats why 180 degree is mostly preferred for Cinematic Shooting.
For Science and such, there may be other factors that come into play when choosing an Shutter angle. For example, if you know there will be a lot of very fast moving Objects, and want to actually get Sharp images of those, while in the air, you want your Shutter angle as low as possible and so on...

Yes Marcus, it was shot at 1000 FPS, but I wanted to slow down the playback to see more detail.  This is 10 FPS, so 100 times slower than real life.
Nikon1 has nailed the 357 Degree blur effect description.

I was trying out some options and playing around with the shutter angle to increase exposure while keeping the gain on zero, and the lens on f4 for a little more depth of field.
If anyone can tell me how to make insects stay in my plane of focus I’d appreciate it!

Love the quality of the image at zero gain.  Will try higher settings today, and go back to narrow shutter angles for sharpness.

I guess luck is a factor and also to try and shoot a lot.
With my current camera i have only Pre-Trigger (Triggering the Recording bevore stuff happens, record time 3 Sec).
With The Chronos you could basically just hold the Cam onto insects all day long, and just push the Trigger, whenever something happens, which seems worth keeping. So that makes everything a lot easierer allready

That is my best guess, how some of those very good, very close up insect-Slowmo-Clips came to be.
Someone once said (in a Photography Magazine here in Germany) about an Award-Winning Picture of An Very small, vivid Frog in eye-Level Perspective of the Animal, that almost nobody can imagine how much patience an work goes into images like this.
So i think just keep shooting, you will get great shots eventually!

That's a really clean shot! Also to the people who are posting clips, do you guys use on-board compression? Like do you let the camera compress the files for you, or do you work with the raw file? I'm guessing raw file will result in better quality?

Excellent first tests, looks to be a really clean image that should perform well even at higher dB gain.  It is already crushing the best I have seen on my 1.4  ;D

Gain test, just increased the gain as the sun was getting lower, leaving FPS, shutter angle and lens aperture on the same(ish) settings.

Decibel or also known as dB is an logarithmic unit. Look it up, if you need more info about it. As far as i am aware, 2 dB more would Double your exposure.
Since the Native (Base-) ISO äquivalent is ISO 500 on the Chronos 2.1, 24 dB Gain should be around 12000 ISO äquivalent, if i didnt get something wrong here.
Will have to do an Side-By side Comparison with an other Camera, to be able to say this for sure, but i think that should be about right.

dB is decebel, a way to measure two relative signal strengths. In this case, 6dB of gain is equivalent to 1 stop, or a doubling of sensitivity. So 24db is four doublings, or 16x gain.


Thanks!I dont know what is the Max Setting, but 24dB Still looks more than ok!Looking great.

I find that 24dB gain on the 2.1 is about the same apparent noise as 0dB gain on the 1.4, the new sensor is really phenomenal with respect to noise!

They're talking about the analog gain, which is measured in db.  Increasing it increases the brightness of the image, but also makes it more noisy/grainy.

I can see column banding becomes much more visible and still apparent at 0dB. My guess is that more calibration will help with that like it did on the 1.4

Very nice Video!Just in the 3k and 5,4k fps shots its a bit much chromatic abberation from the Lens for my taste, or the Camera does something funky in Debayering (That was an problem with the 1.4 initialy also.).

That was fixed by a change of the Default Debayering algorithm in Firmware.If you use Older Firmware with the 1.4 and shoot a scene like this, it still looks very bad. Lots of very colorfull pixels everywhere they shouldnt be....Thats because for very small highlights some Debayering algorithms just assume that this very bright (In reality white) pixel would actually be the Color of the Pixel, and not white.

The "Black" areas of the image have some funky color noise, but the Well-Lit Areas look very nice.   .
Otherwise the best shots untill now. What brand was the 35mm Lens, this was shot on? Was this a Nikon (DX?) or an Rokinon? I guess at f/5.6 it wouldnt make much difference, but still.   .

I can not more use the SD card for saving the video But with a USB key, this is possible
You are talking about the SD card in the top slot, correct? The card in the bottom slot cannot be used for saving.
Could you create a new topic if you are still having problems? I would like to keep the thread on topic.

I've been playing with my Chronos 2.1 for about a month now, and I've captured a few nifty videos. My favorite is probably the gallium. YouTube's video encoding has caused some damage to them (probably partly because my lighting wasn't always the best), but here are a few of the better ones:

Liquid gallium @ 5406 FPS:
https://www.youtube.com/watch?v=o-1o8ISaN4U

Marble vs. water @ 5406 FPS:
https://www.youtube.com/watch?v=r0_ZwUrLOFI

Birds taking off @ 2531 FPS:
https://www.youtube.com/watch?v=6_4yGIhesFo

DLP projector @ 10488 and 24046 FPS:
https://www.youtube.com/watch?v=0oIxPUtv55o

Balloon explosion @ 5406 FPS:
https://www.youtube.com/watch?v=-nKo0CugfWQ

There's other stuff on my channel as well, if you want to poke around (any videos posted before before March 1st, 2020 have nothing to do with the Chronos 2.1).

Ok, you win the Price for the strangest and most creative bit of Chronos Footage i have seen so far. To be Honest, i dont even really know what i am looking at in this Clip....? are the shoes Falling down? My best guess would be they are, and its lit by some Light source which rotates crazy fast on some kind of rig above? or some kind of flash array? And Playback seems to be very slow (like 1 or 2 fps Playback speed?). Would be highly interrested how this one was shot (BTS-Shots welcome, or just some Info on the Setup). Anyways, thanks for uploading!
Title: Re: Post Chronos 2.1 clips here!
Post by: clkdiv on March 10, 2020, 12:52:27 PM
The shoes are from my 3 year old son and you are right, its a flash array. Every single frame of the Chronos got its own flash. Running at 2142 fps the shoes fall down a very little, but nevertheless there has to be some Photoshop post. I suppose when running at 8000 fps or so the post isn't needed anymore. So I am awaiting the Chronos 5.5. The whole clip is made from just 12 frames.
Title: Re: Post Chronos 2.1 clips here!
Post by: Nikon1 on March 10, 2020, 12:54:04 PM
So how did you sync the Flash with the Frames?
Title: Re: Post Chronos 2.1 clips here!
Post by: clkdiv on March 10, 2020, 01:51:14 PM
I use a microcontroller to generate the ttl-signals to trigger both the camera on IO3 and the flashes one by one. It can trigger up to 48 flashes at a speed up to 12000 fps. I hope to do some tests with people soon.

Thanks!

For the water balloons, I just used daylight. It's the brightest light source I have available, after all.

For the water drops, I actually built a custom LED light source using six CREE COB LEDs. I don't remember the exact part number, but they were from the CXB1507 family. I'm running the whole array of 6 at a total of about 40W, so they're bright enough for most things.

It's 1000 fps and so good it's hard to tell apart from Sony A6400 clips that we have on the same video. Lens is 50-100 f1.8 Sigma zoom and I think it wasn't wide open with this one

You are correct, I'm not sure how much gain is reasonable yet.

HOWEVER (I failed to post this message last time, so this is an edit) I've since tried 24dB of analog gain and it's pretty impressive!

Wow, that’s pretty impressive for 24 DB gain and is similar to 0 DB gain on the Chronos 1.4. The low light on that is something else.

i would have loved to use Shorter Shutter Speed and Smaller Apperture for Crisper Images and more Depth of Field, also Lower gain allways just improves The Image.... I need to feed that Camera way more Light for that, but wanted to shoot at least something yesterday, that would be worth sharing. Made Screenshots of the Settings. Also that Denoising in AE CS6 renders forever (i allready knew that bevore and also did a lot of other Heavy stuff on my PC, also its an Netbook from 2015, so considering that its not that bad after all...)
Title: Re: Post Chronos 2.1 clips here!

You could try adding film grain if you want to get less banding after denoising.

i could, but i tried a bunch of stuff with all kinds of adding grain to footage a few years ago, and it just ended up completely killing Image Quality after compression for Web/ Delivery. Sure looks pretty nice if you got the Bitrate for that, or even the original uncompressed file on your end when Shooting/ Editing, but the final image, the Viewer gets to see, that is compressed looks even worse then the original with the banding... Might try very subtle grain at some point, but for now i wont add any grain untill i got good enough handling the Camera itself, still rather Tricky for me to find the Sweetspot for some Settings but i will find it out eventually.

Wanted to shoot something today in Sunlight for the first time, and found some Fly that was very interrested in the Chronos 2.1, so i picked her up and brought her into frame. Dont mind the Vignetting and Weird flares, i was trying out a bunch of weird lenses for Super16mm which are actually not fully covering the Sensor, but still very nice and Sharp otherwise. Settings: FullHD @1000fps, 0db Gain, 88° Shutter, Schneider Kreuznach Xenon 25mm 1.4 @ f/4; Grading and a little bit of denoise in AE.

Slapping Bottle gently. Settings: FullHD @1000fps, 0db Gain, 88° Shutter, Schneider Kreuznach Xenon 25mm 1.4 @ f/4 or f/2.8?; This time no denoise at all (meaning way quicker render), just a preset for color from Magic Bullet Quick Looks, a very Quick Contrast adjustment with Curves (Cutoff to make blacks blacker and White more white), and a small amount of sharpening. Also Higher Bitrate render this time.

My USB-Soundcard finally broke completely yesterday after Years of hard use and Abuse. Litteraly into pieces... So today i went and bought a New USB-Audio-Interface. And the first thing to do with it is obviously hooking it up to the Trusty Hameg Osciloscope and blast Globetrotter on it to film it with the Chronos. Looks way better than the old one. Settings used: FullHD @1kfps; somewhere around 180° Shutter; 0dB Gain; Schneider-Kreuznach 50mm 0.95 @f/1.2; No grading/ Editing/ Sharpening on this one, also no denoise, just run it to AE very quickly to compress it for posting here and turn up the Saturation a bit on the Green. This one is rather long, but i kept it as is from the Camera .h264 .mp4 File anyways.
 Also, i just noticed, i maybe forgot to do Black-Calibration on the Bottle one, hence the Weird Lines all over the Shadow areas in the Image. Have to keep an eye on this, but still new to the cameras Workflow, so Black-Cal is a thing to remember bevore shooting important stuff.

Just curious. How many hours of battery life are you getting on yours?
I only got through 1,5 Battery cycles so far, so i cant really say anything from experience yet, also i didnt watch the time with my first bit of goofing around.... But i noticed that on the First Shot with the Screws, which i did in the middle of the night with my "weak" 50W LED Panel and High gain, the Camera got way more hot than with the other Shots on 0dB gain today, with better light. so i would expect that more heat means, battery drains faster, and that High gain would draw more power. But that is just a wild guess from my side right now. Time Will tell about that. However, just from my general sense of time, it drains rather Quick, at least compared to my Nikon1 J5. Have only used those very rarely, but i think (based off the first battery cycle and my few hours with an Sony A7ii...) battery live is somewhat compareable with the Sony A7ii, when i used it indoors for event shooting (Mid-High iso, not too much light... Shooting images, not video, basically change battery every like 20 to 35Minutes to make absolutely sure you dont get below 30 or 25% at any point in time, to not miss potentially important shots). Battery live is kinda decent for what the camera does, in my opinion at least. I mean at least its stand-Alone, runs off of a battery at all, and has an integrated Monitor. Looked at 35k€ Highspeed-Cameras, that need an huge Beefy Power Brick and a PC to even work. Camera itself is just a 3" Cube with a mount and an Ethernet Jack... With the Chronos you can actually get work done, without an hour of setup...
 I really have no idea but i guess it must be between 1 and 3 Hours, lost track of time when playing. For what i do, its certainly to little battery live to leave the house without additional Batteries, so i will buy two more batteries and keep the three as Backups or for Smaller Shoots. But i think i will go with V-Mount for Power. 200Wh V-Mounts are Affordable, tough, and i allready have a bunch for my lights, so they will be around for shoots anyways most of the time. this should allow for Plenty of shooting time without changing Batterys.

Well, things like Voltage Converters do exist....:

 Plenty of those are available in all kinds of Voltage Variations. If you need some Strange Voltage, it wouldnt also be all that difficult to build one on your own for some Special Voltage...

Just curious. How many hours of battery life are you getting on yours?
I just did a propper test, charged the Battery untill the Status LED turned Green, disconnected charger and Powered the 2.1 on. Then waited for the Startup Sequence to finish, double check Settings very Quickly (Set it at FullHD 1000fps, 180° Shutter, 0dB Gain, no lens mounted Just a Bodycap, so completely Black image all the time), doing a Black Calibration and hit record, so it would allways just record to RAM over and over. Letting it run that way, recording, waiting how long it would hold untill it would stop recording. From the Moment of hitting the Power button to power it on, to the Camera Showing 0% Battery live was around 1 Hour 7 Minutes, but it didnt Stop recording, so i left it running. At exactly 1 Hour and 10Min 0 Sec it hit 8.88V and i stopped recording, powered it down (soft power down, no hard power down) and hooked up the Charger again, because at that kind of voltage i was pretty sure, that the Chronos itself would propably not stop recording any time soon on its own, but i will possibly damage the Battery because of deep discharge. I dont know what will happen, if you just would continue recording way after 0% Battery live, but 8.88V was the point, where i decided to stop. At some Point either the Camera itself or the Battery will give up, but i dont want to challenge damaging something, especially the completely new battery.
 For any further Questions about batteries and such, if there are any more, it would propably best to move to an other topic with this or make a new one to not get off topic with this one, which is supposed to be a 2.1 Footage Thread.

As far as I'm aware recording does not consume more power than idling.
The power consumption is pretty constant apart from the fan, which obviously depends on the external temperature.

The power consumption is pretty constant apart from the fan, which obviously depends on the external temperature.
For my test today, Room Temperature was 26°C for the whole test. But i think you are right, heard something like this also somewhere.

Hi B.H.V
Thanks!
All but 1 clip was at 1.000 fps.
I tested out all the different file formats, and and as expected I perfered the Cinema DNG files.
Still trying to figur out how to get the cleanes image out of the camera, with out to musch noise in the blacks and visible vertical lines.
Right now Im adding filmgrain into the image after the noise redution.
Super fun camera to play with!

i was also thinking about getting one, but the price was holding me back for now. Nice you got one! how is the small apperture working out for you when shooting Highspeed? Would assume that thing needs wicked amounts of light for anything indoors at 1k+ fps....? also, how is the Weight distribution/ balance on the Lens? is most weight of it in the back at the mount, or is the balance point somewhere in the Midle? Just asking, cause if Balance isnt too front heavy, it might allow for some really unusual and Strange shots and angles on an gimbal.
Title: Re: Post Chronos 2.1 clips here!
Post by: clkdiv on October 16, 2020, 02:01:47 PM
Hmmmm, what angles are you thinking about? Any ideas I should have had myself? :-)

The whole thing isn't heavy at all, and most weight is at the cameras side, I think. If you want, I can examine that for you.

I have been to a local dealer who had that lens on stock, taking a Godox 200 with me to test how much light it needs. As supposed it needs tons. I saw Steve Giralt and his clients in a making of clip wearing sunglasses. You will often find yourself wearing sunglasses, if you buy this thing.

ok, i like really bright lights, but so far never found myself wearing Sunglasses because of lighting, so THATS BRIGHT!
 Thanks for the info on the weight, wouldnt need any further info on it, if its not really heavy on the front its fine. Should work on an gimbal then, if i would ever end up using it on one
 I personally would use it with a speedbooster, to make it wider and also to gain a bit more than a stop of light on it.
 For crazy angles, think about a fast push in into some tight, fast moving Machine or if you are mad brave, stick it into an wasps nest and pull it out really quickly. While this is actually pretty crazy, this lens would be really nice to have, even if i never did either of those two, to get into tight spaces. Also the Image on that lens is just so surreal looking from every test i seen, and while the Small apperture is tricky because of the Amount of light you need, the huge Depth of field is great. ALSO that lens actually can focus really close as far as i am aware, which i really miss on about all bigger format Wide angle Lenses which are not special Macro-Lenses.
Title: Re: Post Chronos 2.1 clips here!
Post by: clkdiv on October 18, 2020, 04:01:42 AM
If you really use the lens in a very small space, then it is not that hard to get enough light, I found out. However I could not stop down enough when filming at 1000 fps. So for testing purpose I switched the Chronos to 60 fps.

Now I don't have a slider, so I tried to build something on the fly. That turned out to be useless, since every small disturbance of the motion translates into real shaking with the Laowa "Stick". Also, when stopping down to F40, even the smallest piece of dust on the sensor becomes visible.

So using that lens at 1000 fps not only requires sunglasses and massive light but also a very stable camera slider.

Here is a test that reveals the upcoming problems (https://vimeo.com/469440551).

Now as you mentioned the speed boosters, they came to my mind again. I forgot about them, but now I need to know what I could do with them in combination with the Laowa. I resurrected the Speedbooster-Thread (http://forum.krontech.ca/index.php?topic=123.0) again for that.

Is this shot at 1000fps? or 60?Even if your Slider is a bit wobbly, when you do a crazy fast push-in on it at 1000fps, alone the much slower playback should smooth out a lot of the motion your Slider Might produce. Also most better sliders can be re-Adjusted, for example for Wear and such. Out of the box most wont be too tight, because then they dont slide as freely, but for something like that shot with macro stuff closeup on a long Lens-Stick thing, you might want it a bit tighter, since that also reduces Play by a lot usually.
 And Yes, you propably want to clean your sensor and frontlens/ lens Back element when using that lens...

That one was shot at 60 fps.

Yet another attempt with 120 fps (https://vimeo.com/469590607). As soon as I got the money, I will put a speedbooster between the Probe and the Chronos., because imho too much of the wide angle is lost... Nevertheless, the lens is fun.

Video Link doesnt work for me for some reason. An idea would be to try and record some kind of "empty frame reference", so just an very evenly lit white surface with the same Settings as whatever you shot your footage with lines at and expose it to something like 30-50% grey. Should still record the Lines then and can then just be removed in post production with the correction mask you just recorded. worth a try, also gave me a kind of useable result when i did that 12fps test without propper Black Calibration which on itself was basically so bad image Quality, you couldnt even really see what it is supposed to be. With an (in this case Black reference) reference Recorded at the same Settings i was able to clean the Image up in post significantly and it ended up looking surprisingly good in comparison to what i started with. Would propably try to record a bit longer, not to just use a single frame as such a reference. Will mostly end up looking more organic if the reference is taken from recorded footage, not just from one frame.

Here are a few clips put together.
It's a really fun camera to shoot with, but I can see that I need to work hard on my lighting.
With this camera, lighting is EVERYTHING.
I'm getting better and better images out of the camera the more I work with it.

No, that's not possible, imho. It's a stepper motor turning the focus wheel at the lens and another one moving the spoon.

Hey Kristian, would you mind sharing your experiences and findings with light settings? It is really great what you are doing there, and I'd love to see what you use and how you setup things... :-)

Finally got myself some propper LED-Lights and did a quick test with them today. 2142fps @146° ; 0dB analog 6dB digital Gain (Had set the Digital Gain to 6dB for a previous shot, and didnt double check again, cause i usually dont change that setting, so because of that, there is some faint noise there), f/16. Lens used was an 12,5mm f/1.3 Avenir.

This Short bit of footage here is a bit of an crossover from that topic here:
 https://forum.krontech.ca/index.php?topic=614.0
 It is shot without the internal IR-/UV- Filter glass, which makes the Image somewhat more soft, but noticeable brighter in some situations. This was shot as kind of a test to push the Cameras to its limits on Low-Light. Shot at 46fps; 359°; 18+6dB; f/0,95 50mm Schneider Kreuznach Lens wide open.

I guess with a *bit* more air behind it, you would propably easily get a Watermelon up to speed and floating. I am thinking much bigger, something like this, propper madness (the dude there is crazy enough to maybe even try it himself, if you asked him):

 (https://youtu.be/9vDKSwC9oA8?t=1781) .
 #EDIT: Just remembered, dont you also have some kind of huge air tank with a big hose on it? that would be an idea to try maybe, but somehow limit the Airflow a bit, so it isnt empy in 10 Seconds, so the Melon has a chance of getting up to speed....

Closeup of an Flash tube of an External Camera Flash, Shot on Schneider-Kreuznach Xenon 50mm f/2 @f/22; 24kfps @8° Shutter; 0dB Gain, 46°C Sensor-Temp. Still overpowering the Camera Sensor at those Settings, very bright. (Running on the new Unstable 0.5.037 Update, Vertical Lines on Overexposed Areas on high Framerate Settings still seem to not be completely fixed, but apear less harsh than i remember them from my earlier testing on the Last stable Release (Havent done a side-to-side comparison so far though...)).

This is my first test of the Chronos 2.1 camera.  I destroy simple balsa towers at various resolutions to get a feel for the best quality/speed balance. 

https://youtu.be/wFJdB_NOfBQ

1920x1080 @ 1000 fps
1472x816 @ 1893 fps
1152x648 @ 2992 fps (take 1)
1152x648 @ 2992 fps (take 2)
832x456 @ 5692 fps
832x240 @ 10488 fps

I've been really impressed with the camera so far.  My biggest observation, aside from sticking to the 4 primary horizontal resolutions, is to stay at 0 dB gain if at all possible.  It was much better for me to underexpose a bit and pull up in post than to go to even 6 dB of gain.

All of these shots were at 0 dB gain and shot in Cinema DNG.  There is some post production enhancement in DaVinci Resolve, but nothing extreme.

I've got a picture of my setup at the beginning of the video that shows how I set up the other hardware used: Canon 70-200 F2.8 IS II lens @ F4 and two Godox VL300 300W LED lights with Aputure Fresnel 2X ends.

To use the Canon lens at anything but wide open, I used a Canon DLSR to electronically stop the lens down and pull it off the camera while still on.  While a bit of a hassle, it's not that big a deal and it works well.

Here is some macro high speed using a Dremel to sand a piece of balsa.

Lens:  Sigma APO Macro 180mm f/2.8 @ F11

Playback speed: 50%
  (402x slower than real-time)

It's very challenging to get enough light shooting F11 at 4823 fps 221 deg.  I had both VL300s and a 6000 lumen flashlight about 5" away.

Hello every body
I'm new to this discussion area :) and I'm new to the Slow motion world, I just got my new Choronos 2.1 camera, at the beginning I was shocked when I put my lens and found the picture dimmed and too dark, day by day, after some searches and reading many posts here (Thank you so much all), also after 100 times of try and error, I just uploaded my first time slow motion video  8) 8) 8)

https://youtu.be/W0LHKm8Ekww

Upscaled using Topaz video enhance AI from (640x480) 5406 fps, to (1920x1080), color corrected and speed doubled to 10,812 fps by adobe premiere

Image Quality itself looks very good, also the Shots are Great, as is the music. But for me it doesnt quite play fluidly. Keeps Stuttering a tiny bit. Couldnt quite figure out, if my PC or internet Connection where having trouble, but after even Lowering to 360p Quality it still doesnt play Fluidly, i figured it must propably be something with the Video File itself, you uploaded. Looks to me like the Software may be trying to show some Frames Twice or something because of some Wrong setting. Just wanting to let you know (if it plays fluid for everyone else, maybe it is actually just on my end because of whatever reason?). Otherwise great work on the Video!

There seems to be a slight jerk.
Is the shutter at 180 °?
Quick tip, Youtube compression is much better than Vimeo, especially when there is a lot of detail in the image.
I did some tests with water balloons, and 1000 fps did not seem to be enough. I had better results at 2000 fps 720p and Ai upscale to 4K:

Regular size balloons do pop quite fast. I found them to be a quite good "benchmark" for Framerate Testing or HS-Camera Testing in general. at around 1kfps i usually got around 2 to 3 Frames of the Balloon actually bursting, and this is pretty consistent from all my tests. So the Whole thing is over in about 3ms time or less usually. If you really want to see the Balloon Rip apart, and not only a baloon which is suddenly missing and leaves a Strange Bubble of Fluid or whatever in Midair (which still can look pretty cool), you usually need way higher Framerates or Bigger Balloons, they do Rip way slower.
 .
 Allready posted this way long ago,
 https://forum.krontech.ca/index.php?topic=140.msg1586#msg1586 (https://forum.krontech.ca/index.php?topic=140.msg1586#msg1586)
 This was a test at a german Highspeed-Camera Company, where i tested an 5kfps/FullHD Cam which i tested against my Nikon1 J5 at 1200fps at full Resolution 5kfps /35kfps Max Framerate with all the Same Shutterspeed Settings on both Cameras (on 35kfps i couldnt quite set shutter speed THAT Low on the Nikon, but still did 1/16000s, which was Shortest possible. Was way bevore the 2.1 was even a thing, and i was not impressed by the Dynamic Range of the Cam at all to say the least, i expected way better (the Thing cost 26k€ whitout Tax and needed A Powerhowse of an Laptop to even Run, had no Direct video out, only delayed Output via the PC, and needed an External Power Supply), and they actually reccomended me to look at the Chronos  ;) . Fit my needs very well, also happy about the Price compared to that.

For you guys who are posting clips on YouTube, can you post the raw video from the camera too? Or is that too big of a file?
Depends on how much of a shot you save, a Full Memory Save of a 32GB Chronos will have double digit Gigabyte size in the Uncompressed Formats. Not only takes this very long to Save to Memory, also usualy takes quite a bit of time to upload, even worse if someone has bad Internet. Another Problem is where to even upload Such amounts of Data to share this. I guess some People use Google Drive or something else (i dont...), but even there i dont know what the Limits of that are, and if this would be possible or practical thing to do. Here on the Forum, with the 85MB or something File Limit, and a Typical 2.1 DNG beeing around 4MB (just under 3MB inside of a .Zip) each, longest Clip i can upload uncompressed with one single post here is 21Frames (28 when in a .Zip), which isnt even a full Second of footage (Full Memory save of a 32GB Cam holds 11k Frames at Full Res.). Maybe someone who uses some kind of online File Sharing Service can upload some Full RAW video (RAW Files are also usually longer than final YT Clips, to cut out the Part you want to see. You would mostly save more than you need to show in the end, to make sure you have enough footage to cut) or Share reasons, why they dont upload them.
 .
 So best thing i can offer is making like 5 or 6 Posts in a row here and upload a DNG Sequence of few Seconds, but dont really want to do more spaming here, as the Guys at Krontech still need to host the Server for this Forum somewhere, which also only has limited resources.
 .
 So here is a Screenshot of the Unedited Footage from this Milling-Shot:
 https://forum.krontech.ca/index.php?topic=521.msg3975#msg3975
 , and that was only just over half the Memory saved, and did allready fill a 32GB SD up pretty much. So yes, they are Huge Usually.
Title: Re: Post Chronos 2.1 clips here!
Post by: Nikon1 on February 12, 2021, 07:07:39 PM
Even Compressed Footage still produces pretty big files. Here is a Save of the Other Milling Shot saved in h.264 Compression, i posted the same day here in this thread (saved that one as .DNG and also Compressed). While it is allready much smaller, its still a File of well over a Gigabyte in size.

Post by: Nikon1 on February 13, 2021, 10:44:37 AM
just saying, if you end up buying one, especially the ones with bigger Memory options, and end up shooting a lot with it, prepare a bunch of spare Harddrives, you will propably need them if you want to keep the Footage Long-Term ;).  Those Cams Produce a lot of Data...

Here is a clip showing a balsa bridge breaking at 3540 fps (1472x432).  The camera has the latest V0.6.0 software installed which is a big improvement from what I can tell so far.

This is more in line with how I'm going to use the Chronos with my new channel.  Being able to do failure analysis on devices like this will help a lot in the design and optimization process.

https://youtu.be/oRiQ7f4fXPw

The high speed part starts around 1:25, but I think it's also interesting to watch it fail in real-time to see just how fast it is.
