  • FINAL CUT PRO 29 to 24 frame conversion problem!!!

    Posted by Christopher Frierson on February 25, 2010 at 1:02 am

    Hello,

    We are in the process of onlining a feature film and are running into some major issues. The problem we are experiencing is in the process of placing a 29.97 timeline/sequence into a 23.98 editing timebase. When we do this, footage appears in the 23.98 sequence but on almost every cut and edit both audio and video slip one or two frames OR gaps appear between cuts. The film itself is over an hour and half long with over 8 tracks of audio so we are looking for a solution that does not involve us spending days fine tuning everything back to sync. Has anyone encountered this issue? have any idea what is causing it? or have a possible solution. ANY advice is welcomed, we have to deliver the film in a matter of days.

    Thanks for your help,
    Chris

    Why on earth are you doing this? This is the absolute WRONG thing to do. For so many reasons. What are you hoping to accomplish?

    What was the source frame rate of the footage? The only time I’ve seen these types of problems is when people edit footage at 23.98 in a 29.97 timeline. This is because when a 24P file is put in a 29.97 timeline imaginary (duplicate) frames are created. If you change the sequence back to a 23.98 sequence, then it will remove those imaginary (or duplicate). This will cause gaps to be formed. If you were syncing audio, it might mean that it was synced on a duplicate frame.

    Anyways, if this is the case, you really need to go through and manually adjust the timeline. This is an editing mistake and it’s going to take some boring editing hours to get it fixed.

    If the film was really shot at 29.97, you should really consider a different way of making it 23.98 and really figure out if you really need to even go to that frame rate.

    Chris,

    I’m not sure how you got from one to the other, but it isn’t uncommon to offline edit a feature film at SD 29.97 and then matchback to HD 23.98 sources for the online. There are various ways to get from 29.97 to 23.98, but in all cases, you will be left with mismatches due to frame ambiguities. There is no way around checking each clip for correct sync and each edit for gaps or duplicated frames. Yes, it will take a couple of days if you are fast.

    Was your film actually shot on some sort of 24P media (like film)? Or did you shoot 29.97? If you shot 29.97, keep it that way. You will gain nothing by going to 23.98. If you’re transferring it to film or to a DCP, then let the transfer house convert it.

    [christopher frierson] “ANY advice is welcomed, we have to deliver the film in a matter of days.”

    If you shot on 24P and you really cut in a 29.97 timeline that you now need to convert back, then I would strongly recommend that you find an online editor to do this for you. Don’t waste time trying to figure this out, get someone who does this every day to do it, and find them now.

    Good luck!
