  • 720 29.97fps issue with BM hardware

    Have a simple job to do that unusually isn’t in out native 1080 50i format.
    It’s for laptop playback so we are opting for 720P 29.97fps

    I have a PC set up with a BlackMagic Ultra bridge I/O and that works well on my Media composer V6.5.2 I can create 25P 50i 29.97 projects fine and get output on the HD-SDI output to my HD-SDI monitor and test gear.

    Firing up PPro CS6 If I create a 720P 29.97fps sequence and create some 720 29.97 bars and tone I can’t get an output on the monitor. I can get the second computer screen to play full screen but not the monitor and test gear.

    I did get 720P 25fps to work (and then it didn’t) and 1080 50i works like a charm.

    Does the BM hardware have issues with PPro? Odd as Media Composer works with the same setup perfectly at all the frame rates?

    You’ll need to use the proper specced 720p video signal framerates if you want to use an I/O box. And those are 720p60 and 720p50. Although you can create a project for whatever resolution/framerate you want those are the actual officially specced formats.

    Avid might do some conversion out to the I/O and I’ve heard that some AJA cards do too.

    But wont this give me a 50 or 60 fps output file at then end?
    Which I don’t want as the source is 29.97.
    I don’t really care what the IO does to make that output playable but I need the sewuence to be 29.97

    [Pat Horridge] “But wont this give me a 50 or 60 fps output file at then end?”

    Those are the specced framerates that Premiere and the I/O supports. You can however make a 1080 29.97 sequence (because you can monitor that), edit in that, copypaste the final edit to a 720 29.97 sequence and render out.
