i did remade and change some part of the difficulty and made the singing part much stronger now!
Mapset Verifier says that the video shouldn't use have audio channels. I don't know why but prolly for size.
i tried to do like every single way to remove the sound without the file size become larger but i couldn't, do you have any advice to remove the video sound without the file size becoming larger than before?
Did you cange the export settings to match the video quality? e.g. 480p video inputted, export to 480p or less.
It took me about a days to understand how but here i did it! i remove audio from the video and made the file smaller! if there is anything i need to do more you're able to tell me!
should probably "project sekai" and/or "colorful stage" to tags since the song is now in that game
