Thanks for answering my question. Yes the clips are all on the same drive.I have applied no filters to any of the clips and the settings match up with the raw video. The only thing I can think of is the storage drive I am using DROBO. It seems like it is controlling the application even though I have unchecked the drobo as a scratch drive. The only thing I haven’t tried yet is disconnecting the drobo from the mac. That is the next thing I am going to try.,but it still doesn’t explain why AVC intra is fine and it is having problems with DVCPRO. I will try this test today and post a response. If anyone else is using a Drobo with a Mac Pro and is having problems with it., can you please let me know. thanks
