I have a ".avi uncompressed" file in AE, I want to have an output so I can import it to Final Cut Pro, since Final Cut does not supprt .avi I have to change it to something that it does without any quality loss. so I thought changing it to QuickTime file, but but I don't know if I use QuickTime with Compression type: None and Compressor Depth Millions of Colors+, will the file lose quality or not? or please tell me if you know any output format( with no loss of quality) I can have with AE that is supported by Final Cut Pro.
Thank you for helping,
I know that FCP converts any footage to it's own codec, ProRes, so you might wanna go with that. Use the same frame size and FPS as your original file, and for quality set the max you can. For quality check, I usually import both the original and the converted file in AE, stack them in a comp with Difference as blending mode for the top layer. If the result is all black, then there's no difference between the clips.
ProRes is not lossless, although the quality is quite good, especially ProRes HQ.
Lossless QT formats include None Compressor (uncompressed), PNG, and Animation at 100% quality.
