50p or 60p

Is there a noticeable difference between the two when doing slow motion?

Re: 50p or 60p

There should be a difference as 60p has more frames to work with, if you slow down 50% you get 5 frames/sec more in 30p which should give a smoother motion but I doubt if you would notice it unless you pixel peep.

Re: 50p or 60p

Thanks, I think i'll just stick to 50p PAL.

Reason I mentioned it is because I saw a video on youtube on how to get butter smooth slow motion if your camera can film in 60p and it looked very good.

Re: 50p or 60p

They were probably referring to 60P as opposed to 60i rather than 60P vs 50P so your 50P material will make for great slow motion, especially if you use some frame interpolation software like 'twixtor' or 'slomovideo'.

Full progressive frames have a higher resolution than interlaced but on consumer and pro-sumer cameras like ours, there is a tradeoff called 'temporal aliasing'. High end cameras perform a very short 'dissolve' between frames to smooth out movement. The VG20/30/50 do not offer this feature (costs money and battery life) so a smooth tripod pan for example can exhibit a very noticeable 'stepping' between frames on 25P images and a minor 'stepping' between frames on 50P images. (60P less noticeable, 100P not noticeable, etc)

The solution is to either shoot 50i where each frame is broken into two interlaced fields or 50P (for archive) and render to 50i before post production commences. This is assuming your final release is PAL DVD, BluRay or broadcast Television. If your final release is web based, delivering full progressive is OK.
