Seeking some advice on format to send a final cut project to a color grader we're now working with (not a pro house). We shot on an EX1 XDCAM EX 1080 25p.
My biggest priority is to not lose any quality going from the xdcam in the final cut timeline to whatever format the grade is in and then back to a format for burning to bluray and dvd. It's going through these stages that worries me about losing quality.
I think prores 422 is supposedly lossless but it’s an encode and then if you grade the prores and then render back to prores doesn’t that count for one more drop in quality? I rendered out a prores, an uncompressed file and then the xdcam which theoretically should have been raw output as the timeline is xdcam.
The prores is a much bigger file. XDCAM EX is around 35mbits and the resulting encode is 33,041 which sounds right. The prores is 178,676 bitrate so much higher. I did an uncompressed too and it was 830,976 which is huge. See attached screengrab with file details.
