The width value of the uploaded video was noticeably edited to hard force a wider dimension with empty fill (recognizable in black) to reach up to 640 pixels of width in total: the truly and effective width of this video is exactly 262 pixels. This type of video post-handling should be avoided. Due to its edited resolution/quality, the uploaded video definitely breaks the rule of guideline # 4: "The video quality should be at least 360p". Because clearly, 262 pixels is lower than 360p. The orderliness of this platform means the good for all its users.
