My real-time telecine project

[Stan Jelavic]

Hi Fred,

1. I ran the camera at 30fps (us camera version):
https://github.com/vintagefilmograph...o_with_hnc-hs9
The Pal version runs at 25/50 FPS. I saw somewhere where someone modified the camera but can no linger remember where I saw that.
I never recorded off of HDMI. Used the camera internal recording.

2. In OBS open up device settings and then select custom for resolution/FPS.
Then you can set the FPS but all frame rates may not be available. It depends on the capture device connected.

3. Camera distance, check if you can see film grain.

4. and 5. If the film has deteriorated badly it is hard to get the vivid colors back. With a bad magenta shift you can try using a halogen bulb. They have these at home depot and Amazon. Additionally you can try playing with the white balance in Resolve. You can google that one.

Hi Fred,

1. & 2. For 30 fps recording, the lowest shutter speed is 1/30 if you have AUTO SLOW SHTR on in the Advanced Settings. If that setting is off, the lowest speed is 1/60. For 24 fps recording, a shutter speed of 1/24 is available if 24pDIGITAL CINEMA is on. That's all for the US NTSC version. I don't know if it's the best, but I prefer to use a shutter speed of 1/60, a film speed of 20 fps and a capture speed in OBS of 60 fps. Theoretically, I should capture each frame 3 times, although in practice, even very small changes in the film speed create a mismatch and result in some blended frames (ghosting). I use Hybrid (https://www.selur.de/) to remove duplicate frames and minimize blended frames to covert the captured film back to 20 fps. The results aren't perfect, but quite good in my opinion. There may be a better way to remove blended frames if anyone wants to chime in :-).

3. Every setting manual and any in camera image manipulation turned off. I also manually white balance in the camera with just the light and no film.

4. & 5. I'm not very familiar with Resolve, but there are likely good color correction tutorials for it on Youtube. I use Kdenlive to edit and I can usually improve the color of even a strongly tinted film. Sometimes a scene-by-scene correction is needed. Essentially, you want to equalize the levels of red, green and blue (RGB) in the video. In Kdenlive, the RGB adjustment and Lift/gamma/gain effects works really well to do that. As for stabilization, I usually prefer not to do that. I find that the captures tend to be very steady with very good frame-to-frame positioning, so any shakiness is native to the film. If it's very distracting, I used Topaz Video AI to stabilize, which sometimes works miracles and sometimes looks AI fake. I don't know what stabilization capabilities are in Resolve.

Best wishes,

Robert

Thanks for the insight Stan and Robert. I will continue to experiment with your thoughts and settings in mind. Feel I'm getting closer all the time.
