Changing video information for reposting

Hi everyone,

i have one account which performs really well and started another one on another phone.
I really want to repost some videos on this account, which I’ve recorded on the TikTok account before.

Is there any way to manipulate a video code to make it appear as a new one? I tried InShot, they get flagged right away. I tried screen recording and the same happens.

Does anyone have a solution?

thanks a lot
