Ok. I have a batch of about 50 to 70 one hour videos each to render in MPEG 2 and MP4 each. I am editing in Final Cut Pro 7. I used to export from FCP7 to .mov directly and then convert in Compressor 4. But... I can exporto from FCP7 to Compressor 3, save the file and then open the file in Compressor 4 and render directly in one step. It saves me about 14 hours. But today I wanted to do it again and started to get errors in Compressor 4. Each file game me an error something like "3x: what ever" after preparing. I went back to Compressor 3 and I had the error there too. I downloaded an utility to clean Compressor 3 but it didn't work. I ended up trying using a Quicktime movie and left it rendering with the mpeg2 aspects instead of the FCP sequence , it was taking its time and I left the office. Can someone help me out with what to do to make FCP7 to work with Compressor in one step? Do not mention FCPX, I do not want to know anything about it. Thank you.
