This face-swapping tool is absolutely amazing! I'm definitely trying it out this weekend—going live with my idol's face on! 😆
The legal risks mentioned by the author are indeed something to be mindful of—I've seen news reports before about people getting sued for pranking others with similar tools. Still, it could be pretty fun to use for creative videos~
This tool is so awesome! Just tried replacing myself with a game character during a livestream—the comments exploded! 😂
I'm wondering if this has high system requirements. My old laptop might not be able to handle it...
Seeing that part about legal risks is a bit concerning—this technology really needs to be used with caution. But using it for funny videos should be fine, right?
