Hopefully desktop PC hardware will become powerful enough to gain the ability to skip around in 30 second videos someday. I think I read that they expect them to be at parity with smartphone hardware in the next decade or two.
I simply prefer TikTok for short form videos due to unique community and reasonably entertaining algorithm.
I enjoy YouTube to the point of paying for Premium but I hate that my YouTube subscriptions feed on TV is littered with shorts that I have no way of disabling other than hiding them one by one (which I do to make a point).
Suits at Google will try to shove it into everyone's throats until they get bored and someone adds it to killedbygoogle.com so why would anyone even bother with it.
You can scrub around in them. Look for the red bar on the bottom after the short starts. You can tap and drag on it and a little red circle will appear that will show briefly after you release.
This is a problem with all of these Tik Tok clones (and even Tik Tok let’s you do it for some videos). It’d so annoying to be watching a 45 second reel but if I miss something, I have to watch the whole thing again
