The last image is actually a GIF, not a video. For a proper video upload 3Speak is the way to go. You can create GIFs online easily through various websites, then upload them to Hive, but Hive recommends they are less than 25MB each.
In my experience, I've never been able to successfully upload a GIF to Hive any larger than 15MB. I make my GIFs in the Shotcut, but it's overkill if you're just trying to make GIFs only. Perhaps Giphy might be helpful for you.
Thank you so much!
