Question

How can I create a video file from 35mm film shot with a motion picture camera?

I use a 35mm motion film camera to shoot some scenes of my productions.

 

The area of the images shot by the camera, when scanned at around 4k, is roughly 3648 x 2862. It can also be 2214 x 1712 but I prefer to make a higher quality file.

 

All images are scanned RAW, and I usually drop them as a 15fps sequence in After Effects. Ordering them into an animated sequence is the easy part, but exporting is more difficult.

 

When I export as Lossless from After Effects CS6 (old version, I know), the file doesn't play on any other devices or plays very slowly and is huge (but the frames look decent, the grain is not too badly damaged by compression).

When I export with H.264 codecs from After Effects, however, parts of the image's edges are randomly clipped in the exported file.

 

I tried exporting as Lossless .mov from AE, then converting to one of the profiles in AME called HD 1080i 25 (1.33 PAR), but this step either adds black bars randomly, creates a file I cannot play on recent devices, or compresses the image and the result looks very poor.

 

How can I export a sequence of a pixel size and frame rate that I defined, without losing quality, the resulting file not being playable of having parts of the image cut off?

Set your custom Composition width and height as you prefer and then export using the "Best Settings" Render Settings Template and the "High Quality" Output Module Template.

If you're still tight on space on your storage media, just the "High Quality" Output Module Template to use Apple ProRes 422 LT instead of Apple ProRes 422.

 

If still using CS6, you'll start with the "Lossless" Output Module Template and then change that from Animation to one of the ProRes CODECs.

As long as your storage media can maintain the sustained data transfer rate for a single stream of 4K ProRes, your renders will play smoothly.

If you'd like to know more about ProRes, refer to the Apple ProRes White Paper.  https://www.apple.com/final-cut-pro/docs/Apple_ProRes.pdf

 

Regarding your frame rate, did you under-crank the 35mm camera to 15fps?  I'd go ahead and shoot at a standard frame rate unless there's something specific about 15fps that's working for what you are doing.

The long and short answer is to upgrade your software to a newer version or use alternative tools. Pretty much all your issues boil down to the relevant H.264 specs not having existed when CS6 was around and thus you could only produce a custom MP4 file that may or may not be compatible. Conversely, clearly you have hardware acceleration or generic encoder issues which also boil down to the old code being unable to handle the spec due to them not having been defined back then and the algorithms having been designed for the much less powerful GPUs back then, which imposes its own set of limitations. Rinse repeat for every other format like ProRes or whatever. If it's that mission critical, you should have upgraded quite a while ago. Not necessarily Adobe, though... For what you do DaVinci pro would probably be much more straightforward.
