PTK - Studio shoot - 720p

We want to use the slow mo function on the cameras rather than slow it down in post as it will give a cleaner quality of slow mo than stretching out the frames in post, however, to do this on the sony camera we have to film in 720p. 

We have decided we are ok filming in 720 as the output of our film would be mainly on the web, as an advert on youtube rather than on film or television ( or any where else where there will be a large screen )  meaning the viewer wont really be able to notice the difference in quality that much. They are probably going to notice if we film the slow motion badly more than we didnt film in 1080
