I am still thinking about this problem.
I can record videos with mam camcorde in resolution :
720p (1280x720 @ 50p fps)
1080i (1920x1080 @ 25 fps?)
To this moment I recorded only in 720p, because I think it has smoother screen and better quality. And also I think it will be better to slow motion (and it is, or no? )
Just need to know your opinion. Is 1080i better for normal non-slow motion clips if 25fps is smooth too?
