I thought this was a rule or at least a guideline until I checked the Wiki and it's not anywhere on it.
Strict Version: Does not consider any useful purpose for keeping a video's audio track
If a beatmap contains a video, that video's audio must be removed to reduce filesize. Muting the audio does not count as removing the audio track.
Less Strict version:
If a beatmap contains a video, that video's audio track should be removed to reduce filesize unless insert x reason here. A muted audio track serves no purpose and must be removed.
I suggest the Strict version if there is no good reason to have a video with sound, and the less strict version if there is any reason for it. A side note on the less strict version: It would be nice to point out specifically what leaving the audio with the video is used for and make all other reasons unrankable.
Edit: Cleaned up the phrasing of both.
