  • playback choppy AFTER render

    Posted by Jeff Marr on October 22, 2010 at 2:01 pm

    so i’m editing 1080p24 prores footage from the panasonic 150 in final cut and doing some after effects work to it. I export a pro res file from final cut, bring it in to AE and do my stuff, then export a prores file from AE bring it into final cut and it plays fine on the timeline. Then I put a levels filter on it render it and it plays back with a lower frame rate. Even weirder is if i go frame by frame i can see duplicate frames that aren’t there before i render it.

    this has never happened to me before and after trying to figure it out for the better part pf the day yesterday I’m totally stumped.

    i made the frame rate on my comp in AE 23.976 and exported my prores file from AE with a frame rate of 23.976 and it fixed the problem.

    I didn’t realize how precise you had to be with the frame rates, but now i do.

    thanks

    Sorry to dig up an old topic but I am trying to solve my footage being choppy and I’m not sure if its the same issue.

    I have the panasonic HMC 150 and when I am working at 720P NTSC ProRes and it seems after working for a while the footage gets a bit stuttery and jumpy. I notice it most in mouth movement where it seems frames are being dropped. When I close FCP and restart the program it sometimes is better, when I restart the computer it is usually good for a while. I am running a 2.66 quad core mac pro with 8 GB or ram

    1) could you explain the 3:2 pulldown to me – I do not know what this is
    2) Do you think this is what my problem could be – final output seems fine
    3) any suggestions?

    Thanks,

    Mark

    Basic issues first. Does the sequence match the footage? Is everything rendered? Is your hard drive and connection method (FW, USB eSata etc) fast enough?

    Also what version of FCP are you on. Version 7 when first released had drop frame issues so is your software & OS up to date.
