Compression problems, Does anyone know?
I am trying to make a courtesy DVD for 2 30 minute studio shows. I’ve digitized them into FCP, made a few edits and exported them to compressor. A process I’ve been doing for the past year or so with no problem. I recently upgraded to FCP Studio.
The settings that have worked in the past (MPEG2 60 min high quality preset- 2 pass VBR) are no longer producing acceptable results. The studio footage looks great, it’s talking heads with very little movement, but the b-roll that was used during the show is toatlly unacceptable. There is digital noise at every movement. I’ve tried changing the average bitrate and the GOP. I finally realized that I could do a decent CBR compression and that worked.
What I want to know is, what am I doing wrong with the VBR settings? I guess CBR is good soultion for 60 minutes or less, but I’d like to figure this out before I need to endcode something longer.
