Yeah, I use Topaz VEAI too with some artifact reducing software. Works great for me most of the time.

Hello everbody,

i tried my look with some sparklers. Tested from 1,500 fps up to 25,00 fps.
I get the feeling, that I can't focus it any better but it still looks out of focus some times :(

video available in around 2 hours... i have to go to sleep now an let youtube do it's thing :D

PS: I finally get to test the DAIN program at one of my popcorn clips from my last video.

For only one clip that lastet about 20 seconds my computer took around 3 hours to create a 4 times slower video. ... But the result was stunningly good!!!
But for my kind of video hobby youtube thing, this tooks way too long. But maybe for single clips I can use it. But not for the whole video.

Yeah, DAIN is awesome! The only thing are the render times can be long. But it does get you some pretty nice results on certain footage.

1280 X 1024 to 4K test. This test also shows the difference between shooting 8 BIT MP4 and 12 BIT Cinema DNG on the Chronos 1.4. As you can see, you get way less banding and artifacts compared to shooting on MP4. I might start uploading to Vimeo since Youtube still introduces artifacts and banding that I'm not seeing in the original video. Still you can see the difference between the two formats.

Yeah, Vimeo should be much better.

I found this to be true too on my Chronos 1.4 for exposure. To get less noise in dark areas, I tend to expose image on the brighter side even if it clips a bit. Bringing up shadows a lot in post with the Chronos (especially with the 1.4) can create problems. There is noise reduction software like Neat Video that has helped on my Chronos 1.4 videos, but just donít overdo it so that you donít get plasticky like video.

** Also, did you do any black calibration before shooting? This improves image quality. The consensus is to do a black calibration after turning on the camera, then wait 15 minutes, then do a black calibration again, then wait another 15 minutes and do a black calibration. It's not ideal if you're a run and gun type shooter, but if you don't mind allowing extra time to do this before shooting, I think it's worth it for the improved image quality.

Greetings! If you shoot in DNG, you can use Davinci Resolve. I use Adobe Lightroom even though workflow is slower.

Nikon 20mm f2.8
Nikon 70-300 f4-5.6
H264 Resolve 16
Fijifilm 351 LUT

Really nice. Did you shoot DNG or MP4 for these?

Do you like Popcorn?

Love popcorn! That was cool to see how the kernel pops up in motion.

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 ?
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.
"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...

Have you tested the 0.58X speedbooster on the Chronos 1.4 and made sure the flange distance is okay? Thank you.
