I know it may sound like a weird question, but I'd like to ask about that thing. Since I've noticed that a screen recording for at 5 minutes on iPad takes 1 GB, I've been thinking about editing the video so that the uploaded video features just an actual run. But is one allowed to actually allowed to edit videos with a run? If yes, then to what extent so that the run isn't rejected for a suspicion of splicing? The case is that the original recording features the run along with failed attempts and the edited video to be uploaded is meant to only feature the submitted run. Would I be allowed to edit the video in such a way?

Yes, trimming a recording of a session to show just the actual run is allowed, and is actually generally expected.

Thanks for a reply. I used to upload the recordings in their full form and as much as it wouldn't be much of an issue on a phone (20 minutes = 1 GB), it is on iPad. And the Internet usage is a thing as well. Once again thanks for reassuring.
