    60 fps to 30?

    No matter what time effects I apply to the clip, I cannot extend the clip. I.e. if I apply timewarp to a 60 fps clip, it slows it down, but the clips duration stays the same.

    I’ve read about Twixtor, just don’t have the dough!

    Using AE 7.

    Had a similar problem before.
    I know a good tutorial dealing with this sort of thing.
    check out the tutorial…

    Silly question: is the clip the same length as the comp? If so, should the comp be lengthened?

    I think you need to precompose the clip, open that comp, make it twice as long duration-wise as the clip, so the clip has room to expand wen you apply time warp in the main comp. It’s been awhile since i demoed an AE version with time warp, but it was something along those lines.

    No Steve. The clip is like 00:02:27 and the comp is 00:30:00.

    Okay. I’ll try that Mike. Would precomping do anything to a clip that has no effects applied to it? Wouldn’t that just be like dropping the clip into another comp?

    In the mean time, I went back to Avid ,created a 30 fps clip, and then re-exported.

    Thanks man! Always appreciate the old school tips.

    It’s not interlaced, so that won’t be an issue.

    OK, I think I remember now.

    In the Project Window, select the footage being warped (in the comp below), Right Click, Interpret Footage>Main, and then change Other Options>Loops to 2 (near bottom of panel).

    Now, in the timeline, you can drag the right end of the footage out to the length needed.

    No?

    There’s framerate stuff in that anel too.

    I know I need to upgrade, myBad.

    personally i use dave’s method… i had figured it out a while ago, and i just stick with it…

    but maltaannon has a slow-mo tutorial that should work that sounded like you may not need to adjust the interpret footage settings, just apply a preset to get half-frame rate slow-mo. it was for interlaced footage, but i would think it would work for 60p to 30p just fine.
