Apologies if this is the wrong place to ask this question. Using the upload image button and selecting my mp4 brings up an error red box mentioning something isn't a valid json token. Mastodon communities already make it possible to upload short clips. Would I just link to a Mastodon post?

I would like to gather ideas for those that might want to post small video clips to start discussions. Trying to avoid bloated websites like YouTube for uploading a small 1 min clip.
