[Avid-L2] Re: Video file format for TV stations worldwide

 

Thank you for your comments!
The system we'll use us is born with proxy flash video preview of contents.
What about wrapper for the 525 file? Could that also be H264 to reduce file size?
The files will be of very short duration of a few minutes each so transcoding time is not a big issue.

Best,
Keld
