Right I've been trying to study this 25p and 60 fps for a while...
As I thought our eyes take 100 pictures per second I thought 60 frames per second would make it more real...If the T.V companies play at 25p then why are the T.V's at 100hertz like 100 pics per second to make your eyes ok...Now I'm a noob so please I really want to learn before I Possibly buy the HVX200 in July ?:)?
P.S I wanted to go to a shooting range to record a machine gun..So I thought 50p would be great so I can edit and then slow mo it as it will have captured 50 pics (frames) per second but I just read something that has confused me
PPS:
Why cant playback be whatever framerate the film was recorded on? Like see it at 60frames per sec that way I can pause and move frame by frame with more info when someone moves their hand really fast then it wont blur...
24 fps is Film. 30 fps is video. 50/60 fps is used for slow motion most of the time
Thanks...I've just been reading a bit more on frames and it said that's true but also theres a way to play back 60fps on a 60fps player or something to make it real time and sharper...I'll stick with 25p for the main movie.
Without getting too bogged down in the technical aspects of it, broadcast television isn't ACTUALLY 25/30 frames per second. Well... it sort of is. Each single frame is comprised of two half-frames combined (interlaced) together. So a PAL television signal is actually 50 interlaced frames per second (50i) rather than 25 progressive frames per second (25p), and an NTSC television signal is 60i rather than 30p. This frame rate is dictated by the technical limitations of TV screens. So while theoretically you could run a film projector at up to 100fps (not that there's any reason to do this), there is simply no way to make a television run at a frame rate other than the one associated with its signal standard. This means that films shot at 24p must go through a process known as pulldown in which certain frames are replicated in order to conform to the broadcast standard.
If you're shooting films, especially on the HVX, you'll probably be shooting progressive. Some people prefer the 24p look, some people prefer 25p or 30p (depending on what country you're in) to make editing and television broadcast easier. I personally think that although 24p film looks nice, 24p video tends to be very jittery compared to 30p. Part of that is probably that I grew up watching an NTSC signal on TV rather than a PAL signal and am not as accustomed to video playback at that lower frame rate. Though I've never actually tried it myself, the Panasonic literature claims that the HVX is capable of shooting at up to 60p for slow motion (although there is some controversy over whether this is actually a true frame rate or an interpolated one).
