My view is: if you want to demand something, you have to pay for it.
If I want to see a professional-quality video, I’d have to pay someone; I wouldn't demand that level of quality from someone who is making a review purely for the love of it.
If someone wants to review my game, I’m happy about it; the quality of their video would never bother me.
Would a potential player stop playing because of the video quality? I highly doubt it—but if that were to happen, honestly, it wouldn't bother me. I make games for people to have fun, not for the sake of appearances.
