Export Slog-3 footage from Premiere
on Aug 29, 2018 at 11:04:16 am

Hey Cows,

I have shot a whole lot of stock footage over the past year and I now have the time to trim, sort and upload it.
I want to open Slog 3 footage in premiere and trim it to a certain selection and export that specific part for stock agencies.
BUT ofcourse I want the Slog-2/3 info to be maintained so that whoever downloades the footage can grade it however he/she likes.
How do I do this?

My question:
What method/codecs should I use in order to export S-log 2/3 footage from Premiere Pro, so that it is still gradable later on?

Thanks guys!

This depends completely on the stock footage agencies and their footage specifications.

i'll answer in a purely technical way. if it was 8 bit, you can export 8 bit unless you did denoise as denoising can sometimes create a 10 bit smoothing effect. if not, then just focus on if you want 100% digital copy 1:1(quicktime png or image sequence) or a good enough copy that the eye can't tell and can be generational loss about 5 times before human visible like cineform level 4,5,dhxhd/hr or prores 444,422HQ. (lookup the PSNR values/whitepapers to determine that). project manager can consolidate clips if you're sharing.

I see what you are saying but the point is not whether you can see a difference or not, The point is maintaining the S-log color information so that you are not grading the grey compressed footage but actual S-log after export.

like export out the original log? just don't apply any color grading! if this is what he meant, then he should know that as soon as you place anything into a premiere sequence, it clips the color gamut to rec. 709 permanently. only matters if your footage was originally in a larger gamut. you could use XML as a workaround to keep large gamut footage for resolve.
