For maximum results record using two phones and perhaps it may work with the cup game?
I'm not sure what you're referring to by this statement. Are you suggesting that the guy's trick on IG you mentioned before will be useless if you can compare the video results from multiple devices? I'm not sure if social media/video generation has advanced to the point where they can publish a single video and show two different results. I guess that's true if we're talking about tech like HDR, FSR, etc.
