  • More than one nested timeline causes HUGE lag.

    Posted by Ryan Cathey on April 22, 2008 at 2:59 pm

    When I pull more than one MultiCam timeline into another timeline (nested), PP CS3 lags on updating the main preview window when:

    (1) moving the cursor manually and
    (2) on playback.

    The lag can range anywhere from 10 to 60 seconds before it updates the preview and another 15 to 30 seconds before playback starts.

    The weird thing is it doesn’t lag when performing a rolling edit, slide edit, etc.,. Those customized previews update fine, just as they always have.

    It might be due to the fact that I have keyframes (opacity) either in the MC timeline (individual edits) or on the MC timeline (globally).

    I will do further investigating and report back.

    Nope.

    It has nothing to do with keyframes, either in, or on the MC timelines. I deleted them all and still lags when 2 MC timelines are nested in the same parent timeline. As soon as the second MC timeline is removed, it’s back to normal and all is good, except for the fact that I need 2 MC timelines in the same Parent Timeline.

    I guess I’ll have to “render and replace” one, or both of them.

    If anyone has some insight on this, it would be helpful.

    OK, so I guess PP just doesn’t like 2 MC sequences in the same project at all.

    I deleted the the second MC sequence from the project and everything was fine, but then recreated it from scratch, and we’re back to slowsville.

    Could this be a corrupted video clip?

    I’ll be back.
