Premiere’s laggy timeline – a breakthrough!

After over 130 posts on the Adobe Forums and quite a few people getting involved here on my blog I think we’ve finally had a breakthrough regarding the lag that a lot of us have been seeing when using the timeline in Premiere Pro.

What’s been really confusing is why some mac users have been suffering more than others, was it CPU related, memory, graphics? Well as it turns out the reason it was effecting newer macs more was because they tended to have larger screens and as a result the workspace layout was different.

The thing that causes the timeline to be so unresponsive is the height of the timeline panel itself. The higher it is the more laggy the response of the clips. That’s true until almost filling the screen with the timeline when suddenly the effect reverses.

Thanks very much to everyone that got involved, it really did help as it’s highlighted the scale of the problem and now that Adobe know where to look hopefully they can resolve it.

  1. Since i done the update to Lion, it asked to install “Java Something”. Now my timeline is fluid as it should be! Even when in full screen on my second ACD in 1680×1050.

    Happy! Because i don’t have to work in a small sized timeline :)

    Hardware:
    Macpro 2011 12core 2.66Ghz
    32GB Memory
    Ati Radeon 5870 1GB
    2x OCZ Vertex 2 software raid
    2x 1TB WD Black

    Adobe CS5.5

  2. The Java install question was when i opened Premiere 5.5 for the first time after the Lion update!!

  3. Sorry MACPRO schould be MID 2010 :)

    Turning off duplicate frame detection resolved the issue immediately for me.
