I've recently been asked to export a series of mpeg-2 files for a festival entry (source media is uncompressed quicktime 8-bit). The festival has some very specific details about their entry guidelines:
Encode at 8 MB/second
Audio and video combined into one file
File size: Between 1 MB - 400 MB
I thought this would be a snap in Compressor, but I've been having some serious issues getting these parameters!
First off, whenever I export, even though the Compressor window says that the MPEG-2 setting is set to 720x480 (It won't even let me change it), the final product ALWAYS comes out 640x480. I know quicktime corrects for pixel aspect, but under movie info, it reads 640x480 for BOTH Normal Size and Current size--the quicktime is ACTUALLY 640x480.
Second, on the exports I've done from Compressor, the audio comes out pretty glitchy--lots of distorted clicks.
I've tried exporting both as Program and Transport streams...Can anyone save me here?
