I know I can get this as an MPEG-2, but can we get an H.264 Transport Stream out of Compressor? What am I missing?

Figured out a solution. Reading Wikipedia, I saw that Blu-Ray H.264 is actually supposed to be a Transport Stream. Yes, I found conflicting information it being a Program versus a Transport type stream encode. But in Compressor it is labeled as a Program Stream.

So I encode it as Blu-Ray H.264 with some tweaks for broadcast: Data Rate to 8000, audio Sample Rate to 24kHz, and set aspect ratio, frame size and frame rate to what this specific network requires us to broadcast in.

Then my control room engineer got the idea to change the extension from .mp4 to .trp. Viola! It works just fine! This is a RushWorks layout server, BTW.

So I'm going to try creating a folder, make it the default Destination for my newly customized preset, and with AppleScript made it a Hot Folder that will automatically change the extension to .trp for any file put in it. We don't need to do this often, but the couple times a month we do, it'll save us headaches once that the workflow is set up.

In case anyone runs into this.

Final note, the standard MPEG-2 Transport Stream was rejected by the server for this specific over-air SD channel. But it is accepted by our HD over-air and Cable channels. Go figure...

Very interesting Ben, I am trying to reproduce for the pleasure but the audio is not available...and default extension is 264.
On the other hand i have being able to modify the extension of the file created to trp by editing the setting xml via text wrangler. Can you give more info on your modification process.
Thanks

When I'm back in the studio tomorrow, I'll verify exactly what preset I used, and post here.
