Any 8 core Mac Pro owners out there? I've done some testing and found out that Compressor 3 or 3.0.1 is very slow to transcode DVCPRO HD footage compared to a dual 2.7GHz G5. The problem lies with the 90-150 minute DVD presets in Compressor. My G5 is doing a 6 minute encode of DVCPRO HD 720p footage to DVD MPEG-2 90 minute preset in 20 minutes. The Mac Pro 8 core is taking 52 minutes. I've wiped the system and tried virtual clusters still no speed difference. I've narrowed the problem down to 90-150 minute DVD presets when transcoding DVCPRO HD 720 or 1080 footage. The problem doesn't exist for the other formats including MPEG-1 or HD DVD presets. I would like to verify if this is a genuine problem with the 8 core Mac Pro's. Also DV or DVC Pro 50 footage works with the 90-150 minute MPEG-2 presets. The slow down was with DVCPRO HD and Apple Pro Res codecs.

G5 Ftw!

Sorry, I just had to do it.

The 8 core Mac Pro still beats any other Mac system inside of FCP for rendering. Also in Compressor 3 it beats the G5 and the other Mac Pro's at any transcodes that are not 90-150 minute MPEG-2 DVD Presets. The problem is most annoying because I need to encode to DVD's on a regular basis. This problem is a DVCPRO HD/Apple Pro Res 422 HQ transcode to MPEG2 Standard def DVD issue. Hopefully Apple fixes it soon.

You could submit a bug report to Apple to try to draw attention to the issue.
