Thanks Buddlich!  :) I was impressed by the DAIN interpolation at 4X. The only thing is that you need to have a powerful GPU card for it to run decently as itís much slower to render than Twixtor. The upscale couldíve been been better since I missed focus on the ball, but canít really complain. Iíll have some more videos up. Have some good ideas.  8)

Did something a little different. Chronos 1.4 clip shot at 3,587 FPS in 800 X 480 and upscaled to 3200 X 1920 (forgot to do a Black Cal). It definitely won't be as clean, but I just thought I'd play around with it, and this is the best I could do. Additionally, I interpolated the frames 4X using DAIN to simulate 14,348 FPS. I find DAIN to be better at handling motion interpolation artifacts compared to Twixtor. Lens used was a Computar 8mm 1.8.

Okay, got you.  :) In some monitors, I'm noticing it too so I guess it depends on the monitor. But I think that banding came from a Lightroom slider that I forgot to disable. I'm just seeing it now. Thanks for letting me know. This will help me tweak the upscaling results. Btw, here is the DAIN app link. If you have a powerful GPU card, you can test it out. I'll have test footage to show too either later today or tomorrow.

The downside of Neat Video 5 is the speed. The render times can increase about 4X especially when rendering out to 4K. 1080P rendering is not too bad but still expect about a 1.25X increase when rendering with Neat Video than without it. Having a powerful GPU and CPU will help a ton. The program has an option to use both to increase speed. My system has a six-core i7 8700K CPU and a NVIDIA GTX 1080 mobile card.

Yeah, I mean as long as you aren't pixel peeping and zooming in the upscaled footage, it looks pretty decent. It's weird cause I'm not seeing any serious banding on mine. Are you watching it on an HDR TV? I'll have some more footage in the coming days. I took note of the shots you wanted to see. Thanks again for the feedback.

Edit: By the way, you should try using DAIN. It uses AI, depth awareness when doing motion interpolation so it should be better than Twixtor. It's also a free program but you can donate too. The downside is that it only runs on certain GPU cards and the render time can be quite long. I actually have been doing motion interpolation tests as well. While neither are perfect, I think it has less artifcacts than Twixtor.

I just saw the banding you speak of. That actually a highlighting artifact from Lightroom for one of the sliders. Forgot to disable it.

Thanks for sharing that file. I can play around with it too. Yeah, I heard a lot about the Nikon J5. I wonder why they never continued making newer models based on it. I think a year or two after they discontinued it, the Sony RX100 IV and Sony RX10 II got released that could do similar frame rates but at a higher resolution. One advantage that it has that you mentioned is that it is an interchangeable body.

So here are two clips I did. One was shot at 1280 X 1024 and the other was upscaled to 4096 X 2304. You can see a little difference. Definitely not as drastic as the other one, but I think it is cleaner. Again, I shot DNG sequences for this one. The files are below. I'll shoot more challenging scenes.

Yeah, I agree. I think it really is all about how and what you shoot. When shooting, I try to overexpose just a hair or just expose to the point of clipping so I get cleaner shadows. I think too what you are seeing is motion blur. I tend to shoot at the slowest shutter speed possible to let in more light, and I think I'm going to avoid doing that now just to get less motion blur. They say to always double your shutter speed to the framerate you are shooting. I have another test that I did where I upscaled a 1280 X 1024 file, and that looks even better than this one since I'm upscaling from a bigger resolution. I'll post that one soon, and I'll try the suggestions you posted as well. Thanks for the feedback and info. : )

Yes, Neat Video 5 is great, and I think it's a great investment for denoising video. It even does a decent job of getting rid of edge artifacts. You just don't want to overdo it to avoid plasticy smooth looking video. I also add a little bit of film grain just to add more texture to the image. Here is the upscaling video tests. Unfortunately, I think Youtube compressed the video a bit still so if anyone wants the original file via Google Drive, I can send it. But you can still see the difference between the two. While it's not perfect, I think the upscaling worked decently. The DNG files from the Chronos are very flexible. I'll be doing more tests and if you guys are interested in how I work with the footage, please subscribe to my channel as I'll be sharing more tips on how I shoot and edit with the Chronos 1.4.

I'm using Magix Vegas Pro 17. The combination of plugins I use are Neat Video 5, Convolution Kernel, VEAI and Unsharp Mask. There is a smart upscale plugin in Vegas Pro as well. For these upscaling tests, I shoot DNG to get the best possible quality. I feel the like the DNG files play better when upscaling. I'll upload a short video in a bit so you guys can see the difference. Of course, nothing will beat shooting at a native resolution, but for some shots, especially for close-ups and mid-type shots, it can work decently.

The past few weeks I've been playing around with upscaling files from the Chronos 1.4. I shot this at around 3,500 FPS at a resolution of 800 X 480. The one on the left was shot at 800 X 480 and the right was upscaled 400% to 3200 X 1920 (Click on image below to see full image). I know that it's always best to just keep it at whatever resolution you shot it at, but when uploading to Youtube, it's best to upscale for higher bitrate playback. Not ideal, but it does help. I will be posting a video soon on how I prep my footage for upscaling. Upscaling with good results can be done. I'm still trying to find a good balance when it comes to removing noise and reducing oversharpening artifacts. Please subscribe below for the video. It should be up this week or early next week.  :)

Would love to try this if it's safe to use.

Baltimore oriole at our hummingbird feeder.


Nice capture. Do you see that type of bird often?

Humming Birds, Doves, and sparrows all in slow motion set to music. Filmed in 1500.



Enjoyed the shots! Thanks for sharing.
