Thanks for the reply.
When I open or import any of my mp4 clips and go to File > Export, the “Using Compressor” option is grayed out. The only ones that aren’t grayed out are “Quicktime Movie,” “Using Quicktime Conversion,” “Batch List,” and “XML.”
I must be doing something wrong here, but I don’t know what.
I see that Quicktime has an option to convert to DV. Could I do it there or is the Compressor in Final Cut Pro better quality?
