Re: [Avid-L2] H.264 File Size seems low?

 

Its not unreasonably uncommon. Exporting out of qt pro using h.264 w
best, full 1080, and 320 for audio its not uncommon to be between
50-100mb. Its weird when you're used to uncompressed qt's 300-800mb
but I see it a lot for :30 commercial delivery.

I wouldn't edit w it but for a client or a broadcast commercial dub yes.
