Neurotic-ism makes for good videos. The more pedantic you are, the better the end result.
I think as long as its not presented in a way that implies that “RecRev presents” or that you are sponsored by them, then its ok.
I wouldn’t put it at the very beginning of the video, (unless it’s perhaps after your name, but even then using the name of the exact yoyo rather than the company as a whole would be more appropriate) nor would I put it at the very end as doing so puts too much emphasis on the company. That’s what the big companies tend to do; CLYW either put their logo before all their official videos, or at the very end, and I think it would be inappropriate for someone to do the same if it wasn’t an official CLYW video.
Same goes for the video title. If it’s “CLYW presents: Ivor Sawfingah” then its not on. Whereas “Ivor Sawfingah featuring CLYW Puffin” wouldn’t be as bad. If the initial focus of the video is on you instead of the company, then you should be ok.
Of course I have to ask why you need to company name/logo in there to begin with? Surely if it’s your first major video you would want the focus to be on you, not on the company or yoyo that you are using…?
All just my opinion though. Everyone is different.
