Video it's not 100% clear what you're showing... it's not too bad and ok if you know what to look for but it looks like 1 person scrolling Mastodon users... so if you don't the first part then you don't see a new bar - again not too bad but I think if you want to show more 100% then have side by side scroll as comparison rather than 2 separate videos (if that is possible and not too much effort for you).

Actually the picture was x10 better than the video for showing this feature!
(but doesn't mean video was bad)

If you had video showing that whole picture or just right side of it, then it would be good or without any doubts why there is a video of someone scrolling lol

Picture could be at the beginning or end... but yeah the picture definitely solved that question
This comment is if you want it nearer 100% in my evaluation and if it's important people don't just go to next video and see "ah that's clever"
Watching the video was like 'spot the difference' games!
