what is the line that shows across such videos on Tiktok?

Maybe it somehow counters copy right

It’s to protect copyrights

What line?

It changes the video just enough that the AI doesn't see it as already posted or copyrighted content so dodgy channels can post the videos and monetise it and not get caught for a little while (at least till they get caught trying to countermand the copyright protection and get get all their accounts banned or the copyright owners file a DCMA claim and come after them directly).

It's not that hard to work out tbh.

Same reason why some videos are inverted.

And the reason why they all use the same stupid soundtracks is for the recommendation algorithms. It'll know you watch certain videos with certain music more often and recommend more of those videos to you.

Cut line

I see the argument that it's being done to try avoid auto copyright detection, and I'm sure some people posting are doing it for that reason, but I've seen quite a few channels that sometimes upload split screen clips with subway surfers on the top or bottom, and when they post clips without subway surfers then it has this line, and so I think those channels just have an editing template they're using that splits the screen, and so what when they post only one video, you're seeing the template that would usually divide the two seperate videos. Especially since you usually see this on the smaller profiles and see whole movie clips not being taken down without the line
