This may be a bit of a stretch to post here (in terms of whether people will have an answer), since this is a fairly specific question about video work, although I am performing the entirety of this work within FCP 7, Compressor, and DVD Studio Pro.
I have 2 hours of footage edited from a HD Camcorder in FCP 7, and I need to get it onto a DVD. I want to use the highest quality container I can, and I want to be able to author and preferably burn the DVD within DVD Studio Pro. Unfortunately, DVDSP doesn't support MPEG-4, which is one of the nicest containers to put 1080p video into. It supports MPEG, which offers considerably less options for compression, and data rates.
Ultimately, my question is HOW can I export my video out of FCP (or Compressor) so that I'm sitting on a high quality file that will fit on one DVD and be compatible with DVD Studio Pro (4.7GB)? I just finished a 24 hour Compressor job with the default setting "HD DVD 60 minutes", but it gave me a 5.1GB file, which is of no use to me. The aspect ratio is also forced and it looks terrible.
