  • Frame Rate Problems with Quicktimes- and now a newbie!

    Posted by Joe Carusoe on February 22, 2009 at 11:38 pm

    i’ve been using AE for almost 15 years, and this has got me stumped:

    for some reason when i bring quicktimes into AE CS3 and then nest them into a composition, the frame rate is off. every 4 frames AE is repeating a frame. looks like a field issue, but AE’s doing this to every quicktime i bring in, and damn if there’s NO interlacing / field issues going on otherwise.

    the QT is 23.98 fps, the comp is 23.98, but i’m getting repeating frames.
    and i can’t figure out why.
    anyone know?
    thanks in advance!
    cheers

    Sounds like a pulldown issue. Check the QT’s Interpret Footage dialog for more info.

    i’ve poured over the ‘interpret footage’ settings…
    everything’s set to 23.98 fps- how the footage is interpreted, the actual framerate of the imported quicktime, and the comp itself.
    it all matches up… but still i have repeating frames.

    Just a thought: the frame rate should be 23.976 fps, not 23.98…

    … in spite of what Apple says. AE is very picky about it.

    If that doesn’t work, give us the exact process from shooting to AE. What frame rate was it shot on, how it was captured, was it telecine’d, is it stock, was there pulldown, is it 24p video, all that stuff.

    What’s up Brent! It was a surprise to see your name on here today. I’d have to agree with the others, it should be 23.976 . I had that problem a while back and it drove me crazy too.

    Seeing that you’ve been doing this for so long, I wonder if there isn’t something else going on though. I’m sure you’ve worked with this type of footage shot in this particular way at some point. Let us know if setting the fps to 23.976 doesn’t work for ya.

    What they are saying should definitely solve your problem. I have found that if I create a new comp using the the preset for 23.98 (24), I have to manually change the frame rate to 23.976
    If I drag 23.98 footage to the make new comp button (my usual M.O.) it creates a new comp at the right frame rate (23.976)

    hey everyone-
    thanks for all the responses (good to see you ’round here too, jeremy!)

    so this is one of those Fork-in-the-Eye things…
    i drag in a quicktime, and it plays with these extra frames i’m seeing.
    if i open it in Quicktime, copy all, paste into a new quicktime, then drag THAT one into AE it plays fine.

    is this a codec problem? the quicktimes it’s having trouble with are all 23.98 fps Apple Animation quicktimes (thanks, apple!).

    changing the frame rate from 24 or 23.98 to 23.976 in both the ‘interpret footage’ settings and in the ‘comp settings’ does absolutely nothing!

    at least i get five dollars out of this mess… : )

    Hi everyone!

    I’m encountering the same problem as well!

    When you say “if i open it in Quicktime, copy all, paste into a new quicktime”, do you mean to open up the video in the Quicktime player, then exporting it out as a new Quicktime file? If so, I tried it and it’s still the same!

    However, when I first tried it, I was using Quicktime Photo Jpeg. But when I exported the video out as Quicktime Blackmagic, then re-import back into AE, IT WORKS! I have no idea why though.

    Does anyone have any ideas or solutions? Though this method works for now, it increase my working time by a lot. not very productive… 🙁
