can anyone tell me the editor he used? (can't open the youtube link)
the website used to remove the background in the link embedded in the OP: remove.bg
I often use this to support my work as a social media admin. It's fast, effective, and detailed, we can also choose the size, whether it's HD (1080x1080) or regular (500x500). Haha, this isn't a promotion, I'm just sharing experiences.
This website really helps my job when the computer device does not support graphic design. It is also very helpful for beginners who are not familiar with Photoshop and the like.
For me, any application we using for creating articles or video background are good to go, as long as our content is genuine.
Many hunters plagiarize other's content to create theirs which is not fair for genuine content owners.

Of course, as creators we have to maintain an attitude about authorship. imitating other people's work is a violation, plagiarism, please report it immediately if you find something like that in the bounty campaign.
