Activity Forums Apple Final Cut Pro Legacy Nesting Sequences Problem

  • Nesting Sequences Problem

    Hi,

    I am working with Final Cut Studio 2 on a Macbook Pro (2.5GHz, 2MB Ram). For the first time I have been working on a project with nested sequences (as a regular AE user this comes pretty handy to me).

    Basically I set up one composition with the basic cut, color corrections, transitions and Alpha overlay clips.
    Before nesting this one in another sequence all effects were rendered.
    Now when working with the nested sequence I just added a mask overlay and added some subtitles plus cut some parts and added music.
    Also in this sequence all effects are rendered.

    Now here comes the problem… I get some pretty messed up playback, obviously at times where I got 2-3 layers with alpha stacked in my first sequence, so only when there is about 6 tracks in one frame (adding the tracks of both sequences). Here at times my playback stutters back and forth, drops frames and throws in frames that have already passed so I have to work kind of blind in these parts of my cut hoping that everything is alright.

    This only happens on playback. When exporting the sequence to a QT-Clip everything is fine. Is this a wellknown issue with nested sequences or did I just run into the limits of what FCP can handle on a Macbook Pro with my specifications above??

    Thanks for any replies in advance,

    Karim

    I’ve had hiccups like this too on occasion with nested sequences – sometimes playback is bad, but output ends up fine…

    Sometimes if you break the render and re-render and it ends up back to normal.

    Hi Jason,

    are you also working on a Macbook??
    And what do you mean by “break the render”?? Just trash the render files and re-render??

    I’m working on a Mac Pro. Trashing the render files would break the render, yes (and/or any change to the nested sequence would also).

    Nesting in FCP is, to use a technical term, wonky. IMO a better, although less flexible route, would be to export a self-contained QT movie of the sequence(s) instead of nesting them. Obviously any changes made would require a new QT movie to be exported, but it would keep things running smoother.
