The filesize of this map is too high. Sadly, I don't think you can use separate videos for each difficulty. Having dancers may be possible in the future, but doing it this way makes the file too large to download.
If you use a low-res, low-bitrate h264 encoding, and can get each file ~5MB, it might be accepted.
