Up until now I have been using  seperate still and video cameras but I no longer take the amount of video that I used to and would like to combine both in one camera. I have been thinking along the lines of a Sony A55 or similar.I would like to shoot in HD 1920 x 1080 but am a bit confused with the frame rates available on various makes and models of cameras.Listed are five examples of various camera specs.

1920 x 1080  30 FPS
        "           60 FPS
        "           24 and 60 FPS
        "           30 and 60 FPS
        "           24, 25 and 30 FPS

Would I be correct in assuming that the higher capture rate would result in smoother action on the screen,say panning to follow the action in a sports game etc ?

Does anyone have experience in video with a reflex camera that could give advice on what spec to look for.

Any comments would be appreciated.Thankyou.

If you want to share your videos with other people you need to stick with the frame rate in use in your country and for New Zealand that's 25 frames per second(fps) or 50 fields per second, although now with progressive scan you don't always get the option of 50 interlaced fields to produce 25 frames per sec video and the result can look a bit film like, some people like the effect, now a days with modern high refresh rates on most TV's it's not that noticeable.

If how ever you get a camera that does 50 progressive frames per sec then you have the best of both worlds as there is no need for interlacing to produce smooth motion. don't now how you go on with editing,  25fps 1920x1080i takes a fast computer to edit.

if you view it digitally the frame rates don't matter, the higher the better.

but if you want to burn into PAL or NTSC DVD format then it matters.

ONE THING: can someone explain the relevance of progressive vs interlaced in the modern digital TV (i thought it had implications in the electron shooting tubes of cavemen times?)

also i had the idea that ALL modern video cams capture in progressive ... correct?

It's the editing programs that limit your use of progressive, I think you are right about the cameras capturing progressive, I think that's to keep the file to a manageable size and not eat up to much storage, so  they stick with the old interlaced system as do the editing programs, if you want to edit  PAL 50P or NTSC 60P you are limited to a maximum of 1280x720P,

I believe some consumer video cameras  do give you 50P or 60P but they do it by doubling each frame from a 25P or 30P video stream. I read some reviews last year on the subject, by now it's probably out of date but worth checking before you buy.
