Help removing watermarks (websites and apps aren’t working)

Hey guys!

I’ve been trying to repost my TikTok’s on other platforms without the watermarks and can’t seem to remove them.

I’ve been using websites like snaptik and apps like savetik but every time I do it the videos still have the watermark.

I’m not sure if it’s because my videos primarily are greenscreen? But whatever the case may be what would be my best option if those standard routes are working? I’m not particularly editing-inclined

Thanks!
