Thanks for your prompt reply, Brandon. :-)

Thanks for the reminder about frame size, etc. I have been using 720x480 throughout, with the only changes being bitrates and all those cryptic H.264 encoding parameters (e.g. frameref, bframes, b_pyramid, vbv's, subq, etc.)

I upgraded my QuickTime versions to 7.5 on the Cablecast as well as on my editing workstation. I've also been running more tests. Main@3.0 and Main@5.1 do not work at all for me. I tried with bitrates from around 100 kbps up to 4 Mbps. All of my test files play just fine in QuickTime.

I noticed that when creating an MP4 with QuickTime Pro, there was an option to specify Main or Baseline. But there was no way to do this when creating a MOV directly. So I created an MP4 with Main (it came out as Level 3.0 by the way; the GUI had no way to specify this) and then remuxed it into MOV before testing it on the Cablecast. But still no go.

One correction: I said before that video didn't work at all with Main. My goof... :-( It turns out that my CG/DSK unit was turned off while testing with that profile, so no video was getting through the pipeline. When I turned it on, I was getting some video, but only at about 1 frame/sec.

Anyway, it's as if the Cablecast IS able to decode files using Main, but nowhere near fast enough to do it in realtime. But Baseline@3.0 works fine, even to the upper end of the bitrates I tested.

Unless there's an upgrade to the Cablecast software that enables Main decoding, I think I answered my question about Profiles and Levels. But all the same, it would be great to have a confirmation from TRMS about which ones are officially supported. :-)

Thanks,
Curtis
