My band sometime this summer will be makin a diy music video. We've been brainstorming an would like to somewhat copy what Coldplay did in Yellow (slowmo but still in time with the music). How would we go about filming this. Film it with the song really fast, then slow the video back down in software. Or would we record really slow then speed up in software later ( or would that just make it look like were going really fast). My cousin who just graduated from college with cinematography as his major said they might have taken frames out to enlongate the whole video.

So any help is greatly appreciated

and heres the video if you havent seen it:
