Fresco exports Time Lapse videos, but not to Photos and not recognized by Keynote

Hello. I'm working on a new iPad Pro and I create illustrations. This is the first time I've tried to export a Fresco Timelapse video...  but it will not export to Photos (Save video). I can export to files. But it is not recognized to drop into Keynote or iMovie... Anybody know what's going on? 

I've saved to Files... (and exported to social media from there)... but not recognized by Mac software... hmmm...   I've already restarted apps... restarted the iPad... re-exported... adjusted settings to smaller files. 

I have PLENTY of storage on my iPad...  Anybody know what it could be?
