Question

How to eliminate lag when scrubbing through clips on the source monitor after switching to a different window?

Throughout the work day, there are always emails and messages to respond to along with my heavy use in Premiere. Whenever I need to respond to those types of communication, I’ll navigate away from the Premiere window, craft my message, send it off and then return to Premiere.

Every single time, without fail, the clip I have selected, and was scrubbing through in the source monitor before sending the aforementioned message, becomes unresponsive for 4-5 seconds, the program monitor freezes or goes black and the timeline suffers a similar lag as I click the keybind to go to the next edit point. I’m just stuck there twiddling my thumbs waiting for premiere to respond.

As long as I never navigate away from the Premiere window, this does not happen. I can switch between program and source scrubbing easily. I can queue up different files in the source monitor no problem. There is no lag whatsoever. This happens exclusively when I leave the premiere window to go to any other open application on my machine. Whether that be firefox, chrome, outlook, teams, etc. it always, always happens.

This happens dozens of times a day and I’ve exhausted so many suggested fixes like lowering the playback resolution, clearing the media cache or enabling GPU acceleration.

The machine I’m using has a 14900k, RTX 4090 and 96 GBs of RAM.

    How big is your Premiere project file and where is your media stored?

    The Premiere Project file is 2.36 MB and all my media is stored on an internal 4TB WD_BLACK SN850X.

    It doesn’t sound like either of those factors are causing the issue based on your reply.

     

    It sounds more like Premiere might be struggling to re-establish access to cached media when the application regains focus after you switch to another program.

     

    This can sometimes be related to where the Media Cache is stored.

     

    If your Media Cache is located on an external drive or a custom location, try setting it back to the default location and see if the behavior improves.

     

    If the cache is already in the default location, try rebuilding the cache files:

    1. Close your project.

    2. Go to Preferences > General.

    3. Click Reset.

    4. Enable Reset App Preferences and Clear Media Cache Files.

    5. Click OK.

     

    Premiere will restart. When you reopen the project, the cache files will rebuild in the background.

     

    If the issue is related to a corrupted or inconsistent cache, rebuilding it can sometimes resolve this kind of lag when returning to the application.
