How the *** do you post a video?

What format is acceptable? I’ve tried .MOV and MP4, but neither are acceptable. Please help. Thanks

Hello and welcome! Sorry for the confusion. Best way is to post a YouTube link on its own line (blank line before and after) and it’ll automatically show the nice playable embedded video.

If you don’t want it to be publicly viewable on directly, set to “unlisted” when you upload.

See here for more detail / example of what this looks like when you’re writing a post. (For technique critique, but works the same for sharing any video):
