Perhaps I should also separate "codec" and file format.  I would enjoy 
discussion of both.  I am sure there are additional file formats 
available, so please add them in.

[opendtv] Production Codecs

Anyone interested in talking about production codecs? 

I would like to consider using a "house" video production codec for our 
new facility.  The way I see it, the following are possibilities: 

JPEG-2000 (?) 

Any others to consider? 

Some information on our application: 
-We want to be as file based as possible with solid-state media from the 
field and direct outputs whenever possible (see below). 
-We would like to produce in 720P and 1080i, depending on the client, 
1080i for airing on PBS and 720P for all formats requiring deep encoding. 
-Our outputs include DVD (mostly standard DVDs but blu-ray in the future, 
I suppose), internet streaming, submission to an SD network (OSTN) in 
MPEG-2, an SD cable channel on Cox (live and automated output, with the 
hopes of maybe an HD channel in the future), and internet VOD. 
-We edit using Avid Media Composer and do not plan to change. 

I would prefer to work in 1920x1080 rather than a "thin" raster (Avid used 
that term for formats other than 1920x1080, if I understood them 
correctly).  I don't think we can afford 1080@60P so will likely produce 
in 30P or 60i.   

We can work in 720@60P if need be.  But I hear that it has unique 
qualities and not intermixable with other media. 

So what are the brain-trust's thoughts and experiences?
