It should be sufficient assuming you can set it up well enough to show the game play in its entirety

As long as it watchable with decent audio, it should be fine. If it’s choppy, fuzzy or has chunks of audio missing, etc then that probably won’t be okay.

The general rule of thumb with video footage is that video integrity trumps video quality. By that I mean, as long as the framerate and resolution are CONSISTENT, that is generally viewed as being more important than the video quality itself.

Most moderators I know would much rather verify a webcam recording at 240p 30FPS as long as that was constant and still looked legible than a 1080p capture that drops a lot of frames and has footage missing.
