To clarify:

Of the full distribution of possible video qualities one can take on a modern phone camera, the vast majority of video qualities will be fine for the AI to understand fine details. Obviously, if you somehow or for some reason, take a video with really bad quality, it will not give you what you want.

Same explanation goes for the walls. If you take a video of just a really dark wall with really bad holds, it is probably won't give you what you want either.
