Poster Frames/Thumbnail Generation

. . . exported multiple files only to find that this method also does not seem to create a thumbnail preview of my videos so that I can publish them to social media channels without presenting a blank, black screen.

Check the ingest procedure at the site(s) you are uploading to.

To change the thumbnail on YouTube, for example, see:

Vimeo, also allows you to set the display thumbnail after uploading the file. Not sure about the other social media sites as I don't upload to them.

Editing custom movie poster frames or thumbnails works for me in Compressor and ffmpeg and Finder (Finder uses a different metadata for this, though).

But sharing or exporting such movies to other platforms and social media sites currently does not seem to always/never respect those poster frames and they usually grab the very 1st frame (that might be black) or some other frame from the start or middle of the movie as a poster frame.

Still, stunning that this seemingly simple technological issue has not been adequately resolved.

Yes, sadly movie metadata is still a nonstandard mess. It is no wonder that little things like poster frames do not work when even dates and locations, and also descriptions, keywords etc are still a wild west with various companies pushing their own ideas. Image metadata is not perfect but much better.
