Apple also pushes privacy and on-device processing;

But as for the feature itself: why on earth would you want a video uploaded somewhere else before you've even had a chance to watch it back at least once?

Because you’re showing a colleague how to use a simple inventory tracker that you’ve created in Google Sheets. Or how the new multilingual Figma templates work. Or how to batch rename a folder full of files using the command line. Or whatever, really. You already know what’s in the video because you literally just recorded it. And it doesn’t need to be polished because it’s probably just going to one coworker, who will only view it once.

You can also watch the video before sending the link…

It may not have upload, but in any worthwhile collaboration solution you can literally just drag your screen recording into the rich text area of a comment and have it show up, maybe after converting it to a neutral codec. I did this in my last job with Jira, GitHub, and Slack, ez

Of course you can do this. Loom does the conversion and compression for you automatically so you have an instantly sharable video. Saves me time. That’s the point.

Yep, that's obviously where the value would be, but the basics have been default for quite some time unless you're using a linux or windows workstation

the system video capture on macOS outputs a .mov not an mp4.
