Compressed formats for intermediate rendering
on Oct 2, 2017 at 10:08:46 pm

If I were to export a video (with AME) in a compressed format like H.264 .mp4, for later editing, with the exact same settings that I will later use (again in AME) to export it after editing, will it get compressed and lose quality both times? Or will it not get compressed any further?

In other words, if I took a video and exported it multiple times with the same settings in a compressed format, would it lose quality each time?

Yes.

Consider using an high-quality intermediate format like ProRes, DNxHD/DNxHR, or CineForm. These codecs suffer less visible generational loss than normal, highly-compressed H.264.
