Premiere Pro Lagging

[everyinchaqueen]

     Hello!

     I've been having this problem for the past 48hrs where all of the clips I am editing are choppy, lagging, etc, despite the fact that they have already been rendered. The audio quality is just fine, but the video playback is horrendous.

     I have the latest version of Premiere Pro, that is 12.1.1, and I edit on an iMac (21.5-inch, Late 2009) that has OS X El Capitan, Version 10.11.5. The issue occurring came out of nowhere, and I updated Premiere Pro as soon as the new version was released.

     Please help!

Where is your media located? Local drive? External?

Where is your render cache located?

1. My media is located locally.

2. How would I find the location of my render cache?

Hi everyinchaqueen,

Sorry for this. I have a few questions.

1. Is this a new project or one you updated to 12.1.1?
2. If this is one you updated, can you create a new project and import that legacy project into it?
   • What happens after doing so?
3. If this is one you updated, try a new project with the same footage.
   • Does the same thing happen?
4. As a test, what happens if you export a FCP XML of the 12.1.1 project and open it in 12.0.x (reinstall it if necessary)?
5. Is it possible to update to macOS 10.12? Then try a new project?
   • 10.11 can create a lot of unexpected behavior with newer versions.

Hope we can help.

Thanks,

Kevin

     Hi, no problem.

1. This is a new project that I created with 12.1.1

3. Yes, the same thing happens with a new project and same footage.

4. I receive an error message when attempting to export a FCP XML of the 12.1.1 project. It looks like this:

5. I've just updated to macOS High Sierra 10.13.5 in hopes that it would help, but no dice.

That's not an error message, it's just a notice.

All right, mate, I'm a bit of an amateur, so that's a technicality to me. Any advice?
Thanks.

You wouldn't like it.

This is a help forum, not a chatroom, thank you.

So, thanks to an online chat and some friends in IT, I managed to get ahold of an older version of Sierra, and install it on my iMac after resetting the entire system. I reinstalled Premiere Pro and everything seems to be in working order.
