Compressions for Broadcast
on Jan 21, 2009 at 10:26:55 pm

Hi and thanks for any assistance here.

I may have an upcoming project where the final elements (:30 spots) will need to
be uploaded to traffic for broadcast. I've had a fair bit of compression experience
for rough cuts, but this will be for broadcast.

If we don't want to upload uncompressed QTs (i.e. :30 sec uncompressed SD-say 700 MB),

I was looking for some pointers on an acceptable broadcast quality QT with a smaller
file. I had heard Pro Res 422 was something they were accepting regularly. I have the Avid
codecs, but don't know if the traffic/duplication companies accept that type of thing.

Any other codecs or formats that are generally accepted as being high in quality and decent for
filesize would be what I'd like to discuss.

Thanks very much.
