I'm using Premiere Pro CS6 with a Creative Cloud subscription. I've set up a project to match the MPG settings of my NEX5N camera, IE MPEG I-Frame at 1440x1080, 25P. If I set up an export by "matching sequence settings", those same settings show up in the export, though they're grayed out and can't be modified. This gives me great speed for exporting, since everything stays native.
I'd like to set up a similar export, but at 720P settings for the web. However, I can't find MPEG Preview as one of the export settings, even though it pops up when I match the sequence settings. How can I find this export setting? I'm on a Macbook Air with Mountain Lion, by the way. Thanks!
