On my upcoming feature I'll be using a Gh1 to get some slow motion shots of my lead actor walking. I was going to shoot in 720p 60 at a high shutter and slow it down in post. Most of the hacks I've scene have been for 1080p 24p. Is there any significant quality gain to hacking the gh1 when shooting in 720p? or perhaps now there is a better way to do slow mo?
