What do you like to see in yo-yo videos?
yoyoing xD
Brent Stoles always catch peoples attention the most imo.
True but I wanna know what YOU wanna see 
Smooth transitions and clean tricks with good angles transitions hight quality filming and good music.
Agreed. 
As well as consistency with the angles. I’ve seen videos where the change the angles so it’s like, in one angle the half facing us is A color, and then the second angle has B color facing us. Obviously angles aren’t one clip and filmed, but the technique is supposed to portray it as if it is.
Edit: Also smile and put fun/funny things in the video. Yoyoing is extremely fun, so accurately present it as such.
Slo-Mo.
I like videos that get straight into the yoyoing. Intros are fine, but those incredibly long intros with a bunch of shots of random trees, buildings, rivers, etc. are just too much.
I like videos with high-ish quality. I mean, it doesn’t have to be professional quality, but being able to see the string is nice.
I also like to see new concepts! Creativity! Interesting new ideas! All that good stuff.
Simplicity, and consistency.
like what samad say.
Smooth throwing, and string visibility.
i want to see less brain twister combos
