I have a low cost Kodak ZX5 Playsport waterproof pocket video camera that comes in handy on vacations (hiking, rafting, swimming, etc). This camera has the ability to record in either 720p 30fps or 60fps modes.
I notice when there is any motion recorded, the 60fps provides a significantly smoother look to the recording. In comparison, the 30fps appears jittery and sometimes like a strobe effect. For example, I recorded a test of my son jumping on the trampoline today. 60fps is relatively smooth and looks natural. But 30fps looks jittery and unnatural, like someone moving in front of a strobe light, as if the movement is too large between frames. I don't understand why 30fps looks so bad. Aren't many films recorded with an even lower 25fps? And television is 30fps (although interlaced)? I realize film makers use techniques to lessen jitter, and I have attempted to emulate these in some other recordings, but still it seems there is more to this situation than simply camera technique. I have seen plenty of films and DVDs of the action genre, where there is lots of character/vehicle movement recorded - and these do not look like what I am getting with the 30fps Playsport. Not to mention, by old DV tape camcorder did not have this jitter either - and I think it recorded at 30fps (I will verify this). Is there something else having to do with interlacing, or some kind of blurring, that makes recording devices that share 24 or 30 fps appear different in terms of how smooth motion looks? If so, can I emulate this with some settings in Premiere or maybe After Effects?
I plan to edit the footage in CS5 Premiere, and am inclined to use the 60fps setting for recording because it looks so much better for any type of motion. But if I need to reduce 60fps down to 30fps to cut a standard definition DVD, maybe 60fps is not the way to go? Is anyone editing footage from these type of smaller camcorders, and if so what fps settings are you using, and how are you dealing with motion jitter? I don't want to come back from vacation with a whole bunch of 60fps material and find out it was a mistake. Thanks for any advice.
