Ok guys, this is the story. I have an idea for a music video. It involves the singer standing in the foreground singing into the camera, and the band were going to be playing behind him but in slow motion. To achieve this I tried to shoot two subjects separately and overlay them afterwards before adjusting the timecode for the background subject. I tried to crop and feather the subject in the foreground but as I feared this didn't really work. I am thinking now that Green Screen is the only way forward in order to achieve the effect I'm after. Any ideas?
If Green Screen is the only answer then where do I start?
