Lightroom (cloud) will barely process video. Extremely slow

Question

I use Lightroom, not Classic, daily to process photos. I am now trying to process video from my Canon R5 and it runs so slowly that it is unusable. I simply want to do some basic clip trimming and color adjustments. While I have been able to do those things, I have to wait a minute or more just to open a different clip to apply edits. I have done everything I find online to speed up LR, but nothing seems to work with video. What am I doing wrong?

Using Windows 11, a 8 GB graphics card, 32 gb RAM.

Thanks!

Hey, @Lane23499113pawo. Welcome to the Lightroom Community. I'll help you figure this out. Please share the system info from Lightroom from Help > System info > Copy and paste into a text document > Upload and attach here.

Does this happen with videos imported recently, or stored locally? What is the duration of the videos?

As primary steps, try this:

Unplug additional displays & use only one by default.

Go to Lightroom > Edit > Preferences > Performance > Use Graphics Processor > Set it off if it is on Custom or Auto.
On Windows, you can also set GPU Performance to High Performance.

Let me know how it goes. Thanks!
