  • Frame Rates Won’t Sync – C4D to AE

    Posted by Ned Didry on May 20, 2009 at 12:30 am

    Please bear with me; this is a somewhat complex AE>C4D>AE issue that takes some explaining.

    I’m creating a concert scene in C4D, project set to 24 frames per second, that has a Jumbotron-ish screen that plays an animation, synced to music, that I created in AE (at 24 fps) and exported as a QT movie (24 fps), then loaded into the luminance channel of the material for the screen in C4D. I did “Calculate” in the Animation tab.

    So now as a test I’ve rendered from C4D an 8-second section of the one-minute scene, with a camera pointed at the Jumbotron playing the animation. I rendered as a Quicktime move set to—you guessed it—24 fps.

    Now: I’ve loaded the C4D-rendered movie back into AE, in a project that’s 24 fps, and that has the original music that I synced the original Jumbotron animation to, but when I preview it in AE, the C4D rendered Jumbotron animation isn’t in sync. When the first downbeat comes, the beat-synced motion starts after it, and the animated movements are noticeably slower than the beat of the music. I don’t know by how much.

    I’ve kept every step of it at 24 fps, and I zero idea why they don’t sync up. Does anybody have any ideas about why or suggestions for fixing it? (Bonus question: Is there a high rate of nervous breakdowns in this field?)

    Thanks for your time.

    I solved it by selecting “Exact Frame” instead of “Exact Second” in the material’s Animation tab—in case anyone else wanders this way who has run into the same problem.
