Keynote no longer exports as Mp4

For two years, I created videos with Keynote, exporting recorded presentations as Mp4.

Not, no more.

I would love to get WARNING list of all the ridiculous changes made with updates.

This is massively inconvenient.

I used to be able to just drag that file into Audacity, which automatically stripped out audio, edit that, and then merge back with video in iMovie.

Now I must export as whatever now, import into iMovie (the video bloat machine), export, strip....

This is truly annoying. And RUDE.
