Lightroom Classic 9.2.1 Mac Doesn't Play Videos

For no known reason, Videos that were imported into Lightroom Classic for Mac and that USED TO play now longer do so.

Here's an example:

I double-click on one , and I get a blank player window

Sometimes I'll see just a flash of the video.

When I try and purge the Video cache, Lightroom just hangs, and I have to Force Quit.
I moved the Video cache, with the hope that this would help, but there is no change.

If I open the file in the Finder, and double-click, QuickTime Player will play the video.

Any idea why Lightroom Classic isn't playing these videos anymore?

Thanks.

The command to use is...

ffmpeg -i $your-file-name-here

Open in new window

Also be sure to mention what's changed on your system.

Rarely do systems just start behaving differently. Usually some change precipitates behavioral changes.

My guess is the rotation metadata in combination with the .mov container is causing Lightroom to lose it's mind.

Try this.

Run ffmpeg, doing whatever rotation you require, exporting to a rotated video inside a .mp4 container.

This will drop the rotation metadata.

https://www.ostechnix.com/how-to-rotate-videos-using-ffmpeg-from-commandline/ provides a good overview of various video rotation approaches.
