What kind of system do you need for real-time decode? Decode performance has always been the biggest barrier to wide use of JPEG 2000.

Cinepak? Wow, that’s a blast from the past! Cinepak is 15+ years old right now, and is almost unbelivablly primative compared to anything anyone under 30 has ever seen. But hey, it could do 320×240 15 fps on a 50 MHz computer! And only took 80 minutes to encode a minute of video on that era’s fastest computer…
It was the start of the vector quantization era of multimedia codces, which ended with Sorenson Video 3.
The guy who designed it is now the CTO of Microsoft’s MediaRoom (IPTV) group.

.flv uses either H.263 or VP6. How about you back up a bit and tell us what your content is like and what you want to do with it.

And in fact 1024×576 is the default display resolution for PAL 16:9 (720 * 1.7777 = 1024)

If I’m doing any graphics at all in my NLE, I render out as progressive from the NLE. That way all the fine details in my font are at least rendered in progressive, even though the underlying video will be deinterlaced. Most editors these days will automatically deinterlace interlaced source when rendering out as progressive.

Can you share a link to a sample of what you’re getting now?

Yeah, I’d say 90% chance that’s it’s DV codec and will work in Final Cut Pro as-is.
If you have access to Windows, you can run the free GSpot Information Appliance to find out what codec it’s using otherwise.

I concur on Episode. It’s the best professional compression tool on Mac.
Sorenson Squeeze is also much improved in their new version 5, and I think it’s a lot easier for the novice and non-professional user. I recommend it to educators and other folks for whom compression isn’t a primary job.

As for data rate, with progressive download you can do WMV 720p @ 3-4 Mbps quite nicely, particularly if you use VBR for progressive download.
The new Expression Encoder 2 has the much improved VC-1 Encoder SDK incorporated, so for $199 you can get quite a bit smaller file sizes than in most other products (the Inlet and Rhozet encoders are excellent, and shipping with the SDK, but are $5000+).

Canopus ProCoder, the new Sorenson Squeeze 5, or Flip4Mac’s Episode all meet your overall requirements. ProCoder’s the one I’ve had the most experience with in matching tight specs.
I do worry about your “MPEG-2 for broadcast” item there. Do you mean ATSC-compliant? If so, you may need to go higher-end and check out something like Rhozet Carbon or Inlet Fathom, which are awesome, but expensive.

Expression Encoder is a tool focused on Silverlight, not VC-1 per se. Version 2 was all about improving the Silverlight experience over broadening output format support.
We’re not under any illusions that people would switch to EE for anything either than WMV/Silverlight.
