RE: [Avid-L2] Isis Media Composer using AVXIntra as editing codec?

That's whacked. 720p may be appropriate depending on their network
affiliation, but AVCHD is a pain to convert to and from.

Marc, You are correct. I'm mistaken. It's AVCHD. That's cool? These are MC
6.5 systems running on a mirrored Isis 7000 of considerable size.

Their consultant told them to use AVDHC at 720p. I would prefer DNxHD at
1080.

This is for a TV station in a major market. The news stuff is P2. The rest
is all off of network servers, coming in as some flavor of MPEG2 HD.

I was feeling like the system (which is brand-spanking new) was sluggish.

If it's fine to edit with and it saves space, I'm all for it. Personally I'd
prefer DNxHD and 1080, but that's just personal and I don't know that it
would really look any better, but I feel like at DNxHD 45 it wouldn't save
that much space over AVCHD and MIGHT provide better performance.
