  • Export with alpha to Animation codec-wrong frame rate?

    Posted by Tom Matthies on July 31, 2015 at 1:42 pm

    Looks like this problem has been around for a while but I still haven’t been able to find the answer.
    I have a short “Snipe” assembled in FCP7. I want to export it as an Animation file with alpha to run on air. When I export from the FCP7 timeline (1920×1080 59.94fps) the resulting file Animation codec file runs at about 6 frames per second. It seems to play normally in Quicktime player, but will run at 6fps when loaded into the on-air playback system. The inro tab in Quicktime player also shows an incorrect frame rate. This problem appears to have been known for a while. Is there a solution to get the resulting Animation file to be the correct frame rate?

    The animation codec is an old and inefficient codec requires lots of throughput for seamless playback, are you simply dropping frames during playback because your hard drives don’t have the necessary throughout?

    Also…1080 59.94fps? I hope you mean 1080i59.94…29.97fps. 1080 60fps…ANIMATION…is a HUGE data rate to try to play back. And of course on air is only 29.97.

    I’m sure you knew that…but the 59.94 is confusing unless you say 1080i59.94

    I can’t use ProRes 4444. The device that plays the Snipes back on the air requires either an Animation/alpha file or a numbered Targa or PNG sequence. It takes the file or the image folder and renders it out to it’s propitiatory file format for playback. The numbered TGA method works but it’s understandably a much larger file to deal with and they are having problems positioning it correctly on the screen (OP Error?). The animation file plays in the correct position but it’s playing back about 4 times faster than real time. It’s supposed to be a 10 second snipe. I exported it out of Motion instead and it seems to work OK. Wouldn’t Motion utilize the same Quicktime conversion engine as FCP7?

    59.94 fields per second. I always thought that was just wrong to lost as a frame rate. Actually 29.94 in real life.

    i’ve had weird frames rates from exports in the past,
    a solution has been to open the files in Cinema Tools and conform them to the correct frame rate.

    Excellent idea! I’ll give it a try.
