Embedded videos in Keynote no longer playing on export to movie

I have this problem when trying to display my Keynotes presentation on the external display. This is an Intel based Mac 2018 vintage. Only started happening with Keynotes 13.2 or Sonoma 14.1.1. Same presentations works fine using iPhone and same external display

1 - Make a duplicate of your original Keynote

2 - Right Click on the Duplicate of your Keynote and view the package contents.

3- Open the folder called “Data” and remove your embedded videos contained within it by moving them to another location or folder like your desktop.

4 - Re-encode your videos using “Handbreak.app” with similar format settings but outputting them with “Fast 1080p30” with video encoder set to “MPEG-4”

5 - Open the duplicate keynote file in keynote app. It should say the movies embedded are corrupt.

6 - Replace the media now in the document with your new re-encoded videos.

7 - Now export from keynote again and your new movie will look a lot better.

Same here, Keynote 13.2 creates very jumpy video on export, in Keynote 13.1 everything is fine.

You can let Apple know about this issue here: Feedback - Keynote - Apple

I have this issue as well, but only on my Intel 27" iMac ... when I export from my Mac Studio M1 the problem isn't there.
