Chronos User Discussion / Re: Workflow - Time
« on: June 15, 2019, 09:27:27 AM »
I've pre-ordered one of the 2.1 versions - color sensor and fully maxed out on all options.  Hooray!!!

I didn't add any accessories to my initial order, but I'm planning to add one of everything when the camera is ready to ship.  If anyone has thoughts on what accessories are 'must have' versus just occasionally handy, I'd appreciate your input.  Also, please pass along recommendations for any third-party bits that you find useful.

@Nikon1 if you dont find anyone/ anything else to mount these 2/3" Lenses on that Camera, then Contact me via PM, i will help you find a way,

I'll likely be reaching out to you (and anyone else with experience) for advice and options regarding adapting my inventory of lenses to the camera.  The Metabones x0.58 Speedbooster looks like a perfect addition for the new sensor.  It's getting the MFT part of the speedbooster to match up with the C-mount on the camera that I'm not sure about.

Does anyone know if the Blackmagic line of lens adapters (Nikon, Canon, PL for the Ursa Mini Pro can be put into service on the Chronos?  The adapting part of the process is beyond my understanding at this time.

For now, I'm working up a list of past, current, and potential clients who could use some high speed camera work.  I'm excited to get this camera and put it to use!
.
Sorry, i am not online that often on the Forum lately. Has Been since like Forever, since i was on last time.
If you want to contact me, please use my Mail-Adress, i will send it via Personal Message. If you write here On the Forum, it could maybe take month for me to answer, cause i check on here that rarely.
.
All Your Three Lensmounts you listed could be adaptable. But canon and PL-Mount would Propably require an costum made Adapter. For Nikon-F you could just buy one, since it is a Industry Standard Part.
.
Also i noticed that the Krontech guys updated their Webpage Massively and also saw that insane Bullet-Time Rig thing!
Never Thought about something like this, or that anyone would be actually crazy enough to try build such a thing, but here it is.
I guess we have to prepare for some new stuff, nobody has seen bevore, because we have now affordable Highspeed-Cams which have good enough Image Quality to be useable for serious stuff.
This Thing is really madness in an good way!
.
Hope someone of the Krontech guys Reads This:
Try Combining your Bullet-Time Rig with some Frame-Interpolating plugins, which are used for "Fake-Slow-Motion" where they use it to slow down the footage even more.
You could also use this (an Plugin like Twixtor for AfterEffects) to interpolate Frames when your Camera is "Moving" like on your rig to interpolate Camera-Positions between the Actual Cameras to get even Slower and much smoother Rotation.
From What i Heard and tried, Interpolating 1 to 3 Frames between the actually taken ones should be Possible with good Quality, which would make this some Wicked Setup not only in terms of resulting Framerate/ Slowness, but it should also be super Smooth!

That's awesome! But why do the jaws of the bot rotate at the end? It does not seem to be necessary for the throwing.
I think it is to give some Spin to the Cube.
If it where Flying Straight only, it might not look as interresting.

Thanks for the video.
Yes, i also played around with those RAW Files, and if Shot Properly, this camera can yield some great Results.
Looking Forward to all the Stuff filmed by the 2.1. if it is that much better, as i think it is, you will have a very great time With it.

And here are the Images Of the Modified Nikon D3300, which took above image.
Please someone Confirm, that you could also see the Images online, and that the Upload worked this time.
Thanks in advance!
.
Just while Uploading, i found an image of the BMPCC-Speedbooster for Nikon-F-Mount Lenses (originaly MFT Mount) modified and Fittet onto an Nikon J5 (which was Also Modified to allow this to work). Image Quality is Outstanding, and you get 0,58x Speedboost and 1 2/3 Stop more Light.
I also Adapted this Same Nikon J5 to take MFT-Mount glass at some Point (an Interchangeable Mount...), just dont know where THAT image is...
Just wanting to say with this, if someone has the will to do it, you could adapt basicaly (almost) anything onto an Chronos, if you just wanted it hard enough.
.
#EDIT#: Wait, while Looking at the image again, i saw, that this was still my "Prototyping" Stage of that adaption! This is the Speedbooster with original MFT-Mount on it, untouched, but the Nikon 1 J5 has th 3D-Printed MTF Mount attatched! The Speedbooster later got an (interchangeable) Metal Mount for Nikon-1 Bajonet, and is now a "native" Lens for my Nikon1.

Sorry, Had some Problems and couldnt edit the Post above, and thus coudnt attach the Promised Images. While Uploading some Kind of error happened, and The Images didnt upload, just the Text, and the Page /thread here Was Broken for me since now.
However, here they are (hopefully, if it works this time...).

Chronos User Discussion / Re: Introducing Chronos 2.1 HD!
« on: April 17, 2019, 09:00:21 AM »
2. I saw in the forum there's a thread where the 3D printed C-MTF adapter was shared and seemed to work. The 2.1 sensor is now much bigger than 1.4, which MTF Speedbooster adapter is now working better with the new 2.1 ? the Metabones 0.58x, 0.64x (XL), or 0.71x ?
if you are interrested in Coverage of the 0.58x on the full Sensor of the 2.1 Chronos, i would need to test that, never thought about something like that...
So, here You go:
Just Got around to test the Metabones 0,58x on my Nikon D3300 to test the Coverage of it.
Images are Attatched to the Post.
And no, this wont work with an Stock D3300!
Sorry also for the Crapy image Quality, the Off-Center Image-Circle and all the Shaking and Light-Leaks in the Test-Frame there.
This was An Image Taken By my D3300, From which the Shutter, Mirror and some other stuff i dont needed Was Removed. Basicaly Freelensing on an Camera without any Mount.
Images of that Monster Of an Camera are also Attatched (It is otherwise mostly still an Functional Camera like an Original one).
.
As you can see, the 0,58x Metabones will not Quite Cover all of the Chronos 2.1 Sensor completely, but most of it. Has still an Impressive Image Circle, if you keep in mind, that it was designed for an sensor even smaller than the one from the Nikon1 (which i use the Speedbooster on).
The not-so-extreme other Speedboosters should cover the Chronos Sensor better i think (never owned an other one...).
The 0,58x is still extremely usefull for the 2.1 though, because you will get tons of Light with that Thing (For stuff like available Light / Low Light-Slow Motion)! F / 1.8 will become f / 1 and F / 1.2 will become F / 0.7 after the speedbooster has done Its thing. Also, you will get some Crazy fast, wide "Lenses" If you combine Certain Lenses with that Speedbooster.
.
While looking through the List of Image Sensor Formats to calculate the Coverage for this test here, i realized how WIDE the New Chronos Sensor is.
Also, very interresting Format for that Sensor! Its not Quite AS wide, but still surprisingly Similar in size to the Super35mm Film-Format!
Combined with the Image Quality and the RAW this should be Very Interresting option for all sorts of Filmmaking (even if you dont need the Maximum Frame-Rate all the time...).
AND: 19,2x10,8mm @ 1920x1080px means that every pixel will be the size of 1 / 100mm! This could be interresting for all sorts of things, for example 1:1 Macro and all sorts of Digital Measuring and Industrial Stuff!

Well, i did some Crazy stuff with the Metabones 0.58x (i Own that one), and adapted it to an Nikon1 J5, which works Great. So it will also work with the Chronos as Long as Flange distance is considred. But i am Not sure if the 0,58x will cover the Full M3/4 Sensor Format, which the 2.1 has. For the 1.4 Chronos (full sensor Coverage) and filming 720p with the 2.1, it should be fine pretty sure, if you are interrested in Coverage of the 0.58x on the full Sensor of the 2.1 Chronos, i would need to test that, never thought about something like that...
The 0.71x should cover easily the full sensor of the 2.1, but i dont know the 0.64x and what it could do.
For 1" (the Format, i am used to and use) the Metabones 0,58x is quite insane!
1 2/3 Stops more Light! so your 50mm f/1.2 becomes a 29mm f/0.7!
Optical performance is very good!
3. I wish Krontech will provide customer with prebuilt on-camera MTF mount, which sounds right for a MTF sensor camera.
Standard MTF mount will open a lot of possibility for usage of lens and adapters.
Well...
"sounds right for a MFT sensor camera"
There are lot of Industry Highspeed-Cameras with MFT-Sensor and CS- or C-Mount. This is quite Common thing to see.
So there is nothing too much Wrong about it beeing a CS-Mount seen from that point of view...
.
Also there is some Disadvantages about going with a Fixed MFT-Mount:
.
  • You cant use some of the C-Mount lenses which are Very FAT and need to sit very close to the Mount.
  • You cant use Mount Adapters. Tor the CS-Mount of the Chronos Cameras in combination with those four Thread-Mounting-Points at the Front this means, that you would even Be able to adapt stuff like Sony-E-Mount glass, Nikon Z-Mount Glass, Canon EOS-R- Mount Glass, MFT-Mount Stuff, Nikon1-Mount Stuff, Fuji-x-Mount Glass and a ton of other very crazy stuff via some Interchangeable Mounts
  • If you want to use some VERY short Focal length Lenses (Below 6mm for example...) because you use Fast Framerates (=only small area of the Sensor is actually used= Smaller effective Sensor Size) and still want to go pretty wide, CS-Mount is sometimes your only Option
.
so, you can Make the CS-Mount Chronos an MFT-Mount Camera with an Interchangeable Mount, but if it was an MFT-Mount to beginn with, you cant use anything with Shorter or simmilar Flange-Distance!
So to fit everyones Needs (Dont forget, that the Chronos 1.4 AND 2.1 is also an VERY interresting Camera for Industry-Applications! Not only Cinema and the Like. Everybody likes good performance for an Fair Price!), the way they gone with the Chronos is actually very smart and the best way to do it.
You are Right, "Native" MFT-Mount will give you a lot of Options for Lenses, but the Chronos has way more Options for Lenses, including EVERYTHING anyone will be ever able to adapt to MFT-Mount!
The thing you miss is propably a high Quality Interchangeable Mount (not one, that screws into the CS-Mount, but one that will use those four Screw-Holes in the Front). Just forget about the CS-Mount, if you dont like it, and think about it, as an Interchangeable-Mount Camera (like for example an RED with interchangeable Mount...), but you cant buy the Mounts yet.
If it helps you anything, i (and a lot of other people) could built an Interchangeable Mount like what you want. Or help You with Building / Printing your own...

I suspect you're righ - that the sensor has a fixed readout stage of the full sensor width that it's the bottleneck for the max frame rate, especially since "700,000+" max rate is conveniently ~8x the 8 line speed - but since I don't have access to the full data sheet, I can only speculate and ask for confirmation.

Well, you built yourself an Line-Scan Camera then  ;D
A very fast one.

« on: April 07, 2019, 06:34:21 AM »
Damn!
if i understood that correctly, this LUX8M thing makes the Chronos basicaly an 4k 250fps Camera, that will for Lower resolution basicaly do the same thing like current 2.1 release just be a bit worse in Low Light?
Now i am getting excited here.
I am Asking since ages for that FullHD Chronos, and now, out of nowhere they not only developed one, but basicaly also built an 4k 250fps Cinema camera in the same go?
Still thinking, that it is the best thing for the company for now, to go with the 1080p Modell, since the 4k 250fps Sensor is propably more expensive and worse in Low Light?
Would really wonder, what pricing on that 4k one would be like. Specs and Performance- wise it basicaly is, what any more Professional video camera should have been like since a long time. Just no one of the bigger Companys out there ever cared to build such a thing. If this 4K chronos will hit the market at some point, i think they will sell like crazy if it is priced well, like the 2.1 and 1.4.
.
#EDIT#: Always wondered why you guys at Krontech where so extremely busy, now i know why  :)

Also German here, and i did Absolutely forget, that there Will be also taxes added on that 5000 Pricetag für the 2.1.
Well that sucks.
Just an question, not for me, since i dont have a Chronos yet, but for any other owner in Germany:
If they send the 1.4 camera back to Canada and you do an "repair" or "upgrade" to an 2.1 Chronos and send that 2.1 then back to Germany, will there Still be the huge tax to pay or would that be a way around it?
Just wondering....
.
Also, just thought about it, and there will propably be a lot of people upgrading and selling their used 1.4 Chronos. So i am allready looking forward to maybe find some used ones in medium condition at even lower prices? we will see  :)

Chronos User Discussion / Re: Chronos 2.1 Technical Details
« on: April 06, 2019, 06:28:54 PM »
To be clear here, i am not that much into all that Electronics, FPGAs, Sensor and Internals -thing in cameras like this. I know a fair bit about how it works, but not so much into the Details.
I can Tell you a lot about Lenses and optics in general, but still dont know, what that LUX8M would be able to do (i guess it is an ...faster, Lower Resolution Sensor? just guessing from what you wrote..), what the new 2.1 Chronos cant do or why or how it would be better.
Sure it would also be nice to have much more FPS, but i and many other people where Waiting for a long time to see 1080p@1000fps in an portable, user-Friendly Camera, that would be somewhat realistic to own for an normal Person.
So this is quite an historical Moment right here, especialy since the 2.1 should also have some Serious Image Quality which could realisticaly even be compareable to some Higher End Professional (Cinema-Style-) Cameras.
For now, i think it is very good. Especialy for such a small an young company this is good. The 2.1 will sell very good i guess, and i also think, we will see further improvements (Like maybe higher FPS) in the next generations /other Models of the Chronos.
For any more serious Questions about specific Sensor specifications and so on, someone else would need to answer this, cause i dont know too much about that stuff.

For most Highspeed-Cameras it works like this:
The Sensor COULD put out a LOT of FPS, just the Electronics in the Camera Limit its performance somewhat.
With top of the Line - Highest Priced Cameras i guess the try to use the Full Potential of the Sensor, but for something like the chronos, i think the Developement was going more for overall reasonable Performance at an (for the normal Human) somewhat affordable Price Point (i actually feared, that an 1080p Chronos would be more Like 10k or above in price!). That is, why they propably where not able to use The Full Sensor FPS Capeability, because Fast Electronics, which need to process this Data From the Sensor could get Very Expensive very fast!
.
Because of Max Framerate:
Just Look at something like an Flex 4k and those other Phantoms, that do crazy high FPS at 720p Full Sensor Resolution.
It is quite common, that cameras, that have higher Res. Sensors will be a bit Slower.
I am No expert on this, but keep in Mind, that, even if you dont use it (for Lower res. faster Speed), all the Pixels from the Sensor still are there and the Electronics in the Camera still have a lot more data to process, even if you just use 1920x8.
.
About the weird 1920x8:
Also not sure about this one, but for some cameras (i guess it is the same thing with the 2.1 Chronos) Max FPS won´t chance if you change Horizontal Resolution. That means, your 125kFPS Max will be the Same, no matter if you record in 1920x8 or in 8x8.
That is, because the data is processed in Lines, not on pixel-by-pixel base. If someone knows this better, feel free to correct me, but i think it works this way. Only benefit of going 8x8 instead of 1920x8 would be, that you should be able to Record MUCH longer with 8x8, because the Lines would still be processed, but only 8x8 pixels would be saved into memory.
.
So, it could actually be possible, that you will be able to get more FPS out of the 1.4 than the 2.1, but pushing insane FPS does not look to be main priority with the 2.1, it is more about Image Quality. And that is a very good thing.
Maybe the Kron guys will come up with an crazy high Framerate model of an chronos at some point later, but i think for now, it is a very wise next step from them to go with maximum image quality.

Just watched that 2.1-Demo-Reel again and noticed, just HOW good the Colors (and Dynamic Range) look.
Either someone with great Skills who knows his Buissnes well did the Grading or the 2.1 is just THAT good...?
Colorwise the best thing i ever saw out of all the Chronos Footage around.
Seems like you Krontech guys now got your Color Science on spot right!
If you keep improofing at that speed you will be able to take on Arri in a few years  ;D

« on: April 06, 2019, 06:01:53 AM »
Wow, that is really nice to see, that the Chronos is now finally going Full 1080p!
Now I am Kind of happy that i couldn´t afford a Chronos 1.4 yet, because if i bought one, i would propably not be able to buy an 2.1 anytime soon  ;)
Sensor Size is a bit big for my taste, 1" would have been Perfect for me, because of my lenses, but since it is an Highspeed-Camera, i could still do something around 720p @ 1500fps and still get something like an 1" Sensor size for my Lenses, that wont quite Cover 4/3".
But for anyone else 4/3" is propably a lot better, also it should improve Image quality allready because of that bigger Sensor and therefore much bigger Pixels on the Sensor itself.
AND it will still do 60fps continous (when it is supportet in software at some Point) at 1080p with CinemaDNG-Output on an 4/3" sensor and has Global Shutter. Thats quite something, and would work well even as an Production Camera for Real time Footage.
Also Like the 800 Base ISO! For a Camera like that, this is an actual Live-Saver! But for Real-Time-Filming with it, i am somewhat sure, that i will end up with an ND-Filter on my lens quite often (Which is not a bad thing to be clear).
The Reel is pretty good. This one has some very good Footage on it, and the Production Level improoved a lot since the first Demo-Videos from the 1.4 Chronos.
Even if 5k seems a lot of money, this is actually a very good price for that camera! Looking Forward to get one if possible.
.
#EDIT#: Also, i hope you guys from Chrontech will come far with your Project right here! Love what you are doing here, listening to what people want and sell Products at realistic prices, one could afford!
.
#EDIT2#: I hope that Underwater- Chronos 1.4 was either an Showpice without internals or was defective in some way, otherwise, that would be somewhat sad...
...OR You guys are Developing some kind of Underwater-Slowmo-Cam here and this is Leaked Footage from testing.  :)
