M A V I C, you’re old enough now to know better than to waste time tilting at windmills. I guarantee it would have taken your kid less time to figure out how to use VLC than you’ve spent chasing down a solution to this “problem.”

We’re supposed to get wiser as we get older, pal.

And I probably shouldn't have assumed you all know what Twitch is He likes to make recordings while he plays video games, then edit them and upload to his YT channel. It's a continual thing. He's been bugging me for weeks to fix it. If he uses VLC to transcode, the drive will fill up. Plus when he's not on it, his sister or mom are on it so it can't be dog slow while they're using it.
I know what Twitch is. :RollingEyesSmiley5:

The scenario you described in your last post is ENTIRELY DIFFERENT than that described in your original post — now we’re talking about recording, editing and uploading, not just downloading and viewing.

Given all the other considerations and concerns you’ve cited, I think your best move is to upgrade the family MBA to an M1 model with some external storage added.
Yes, I wasn't fully explaining it. Sorry.
