Hi, I was wondering if there was a way to use exiftool to horizontally flip a video upon playing?  I know there is the -Rotation tag to rotate an MP4, but wasn't sure if there was something to flip a video?  I saw there is a "VideoOrientation" tag, but that doesn't seem to be writable.

No. I haven't heard of any way to edit the metadata to mirror a video. If there was, there would almost certainly be something online. Any search done will show that you have to process and re-encode the video.
"It didn't work" isn't helpful. What was the exact command used and the output.
Read FAQ #3 and use that cmd
Please use the Code button for exiftool output

Please include your OS/Exiftool version/filetype

You should be able to write the QuickTime MatrixStructure to achieve any transform you want, but your mileage may vary when trying to get players to apply this setting.

Good to know. But that also requires that the MatrixStructure exists in the first place, correct?
