I have an odd issue and I'm not sure if it is Premiere's problem or Keynote's, but when I export a Keynote presentation as a movie file using ProRes 4444 with transparency selected, and then import into Premiere, I get this error: "We were unable to open file on disk".
I can workaround it by ONLY exporting the slides in Keynote that have transparency (no fill) and exporting the others separately as ProRes 422. But when I try exporting multiple slides, some having a "no fill" background and some having a fill, then it gives this error in Premiere.
Any idea what could be causing the issue and how to fix? It might be a weird Keynote bug.
Hmm...strange. I would think that ProRes 444 should work perfectly in Premiere Pro. Could you include a screenshot of your export settings from Keynote? I assume there's some kind of export options that Keynote asks you when you export you presentation.
