@CanXClV Mastodon is a microblogging platform, and large videos aren't really in its scope. But QOTO also has a Peertube instance at video.qoto.org which is designed around handling this type of content. The best part is that it's on the Fediverse too, so you can follow your Peertube account from your Mastodon one and boost your videos to your followers here, and they can reply just like a normal Mastodon post.
