Digital Intermediate for 35mm
Greetings,
I am about to prep some footage for editorial and I need some advice about maintaining a High-Quality work-flow before beginning the process.
Right now I have a 63,000 individual PSD’s sequenced and labeled in-order to be turned into actual video files. The PSD’s were generated from 35mm Negatives, are RGB with 24-bit color depth. The files are approximately 3474 × 1332.
I want to preserve the highest quality in in the DI. I would go with the “Uncompressed 10-bit” option for exporting, but this produces files which are too large and unwatchable for my system. What compressions should I look into for my purpose? I am concerned mostly about color information.
Thanks in advance! Let me know if you need any more information from me to answer.

What will the final deliverable be? Are you on Mac or PC? Are the PSD sequences like image sequences scanned from 35mm moving video, or actual still photos?
I would go with a ProRes workflow using the Proxy for offline editing then ProRes HQ for the final.

This are actual stills taken from celluloid film strips. Mac. Pro-res was my default, but it is still a compression none the less. I will loose some quality won’t I?
The final product will be a 35mm release print with 4K digital distro.

Oh! and thanks for responding!

Hmm….ProRes is really for video clips, not stills. How about Tiff format with LZW compression? I’m still not sure what you are working with as the source files…are they single images (one to a file) or like a filmstrip (a bunch of stills strung together into a clip)?
ProRes isn’t the trick for stills. JPEG 2000 is very good especially at that resolution.

I am sorry I feel like I have been non-discrpitive in my problem. I have 63,000 PSD’s (sourced from .tif) and I need to convert them to a video format which is the least destructive. PROress422 4:4:4 was going to be my goto, but it is still a compression and I wanted to make sure I wasn’t overlooking any options that might deliver a higher image/color quality.
Best.
