Thanks for your reply, Bret.
Good questions. The most obvious being why Motion 4. The answer is that it requires OSX 10. My fairly new MacBook Pro had a problem upgrading, which forced me to restore the older system.
The other reason is that I rarely use Motion. It was just appropriate for a small job. And now that I started the project in Motion, I need to finish it.
Of course you are right about writing to a pro format but I’m sending many small updates to a client and it’s more convenient to send tiny files until the final output is rendered.
Mostly, I can’t upgrade the system until I get this project off and I became curious.
I’ve looked all over the place and I can’t see the problem. Doing a Spotlight search for H.264 returns nothing useful. A search for DVCPRO, however, returns scads of component looking doodads. Either I don’t know what I’m looking for or it’s not there.
I can work around it. Just thought somebody else might have bumped into this and knew what would cause Motion, QuickTime, Compressor or whatever to forget how to write only H.264.
Thanks!
