Tips on Importing Source Media Files
Here are some additional tips on importing source media files.
Highly Compressed Source Files
It is strongly recommended that you do not use highly compressed source files, such as
MPEG files, as your source files, because they can cause undesirable artifacts in the encoded
video.
QuickTime Reference Movies
If you submit a reference movie for distributed processing, the Apple Qmaster distributed
processing system will automatically copy the appropriate media files to the processing
cluster. For the best performance, you can avoid this file transfer step by making sure
that the media files specified in the reference movie are available to each node of the
Apple Qmaster cluster. For more information, see How the Apple Qmaster System
Distributes Batches and Using Distributed Processing from Final Cut Pro and Motion.
Importing MPEG-2 Files
When you import an MPEG-2 file, Compressor must parse the file before you can play it
in the Preview window. Parsing the file involves determining its frame structure and other
necessary information about the file. Since the frame structure can change throughout
the file, Compressor must scan through the entire file, which can take several minutes
for longer files.
