Nice to know, some people still have this nasty "<enter anybodys name> did this already in <add anyother video> before" point of view here...
OK, at V there's a low number of released videos at this point, so that "copy thing" should not happen that fast... On the other hand, by the physics change the same runup will result now to a very different landing/stunt...
but all over, any day will someone reland a stunt for a different video again. As long as that person did it on his/her own and did not steal/copy/hack any replay data, it's fine.
I don't care about that "copy"point, may that's the reason why I made only some guest starrings in a few years of stunting back around 2005-2008 - just to avoid this silly nasty "mimimi did that already" part...
Stunting should be fun, if you got fun in editing too, make some videos - it's great as long as you got fun while doing it.
while not everyone releasing the "almost same video" (with equal stunts an stuff) it's fine if a few stunts may repeat. As long its nice to watch, it's fine.
Even if you create a video full of copystunts, it's also fine, if you make a clear point, it's purposed to be like that.
aabout your video:
It was nice, enjoyable, but got one negative thing:
don't 'repeat' a stunt, talking about that one around 1:00, actually it's kinda the same stunt with different landings. take the better/cooler/harder/luckier one and place it in the video OR if you want them both, don't put them that close together. Other option might be a splitscreen thing...
Bringing these almost equal ones directly after another makes it kinda boring, just my opinion about.
