Currently as of the time of writing, the Ranking Criteria only specifies the required format (H.264) and maximum resolution (with a width of 1280 and height of 720 pixels) for video content, but with recent developments such as HDR (High Dynamic Range) that requires specific additional standards/formats (HLG, HDR10, Dolby Vision) and higher bit depths such as 10 or 12 bits as opposed to the usual 8 bits, limits should be placed on the use of such formats as osu! does not officially supports HDR.
Also, with frame rate not being limited, in theory anyone can submit a beatmap with high frame rate video above 30fps or 60fps. Whether it causes problems for most users is to be seen though.
I propose that, in addition to the current format and resolution requirements, bit-depth must be limited to 8 bits and HDR formats must not be used (until osu! supports HDR sometime in the future) and frame rate be limited to a certain limit but I suggest 30fps or 60fps.
This is to make sure videos are limited to a criteria already known to work for most users and that such new features should be tested extensively before being allowed for ranked beatmap use.
