A little more info on slo-mo:
This statement was made above: "Some consumer prices cameras, like the FZ200, have the option of shooting faster frame rates of 120 or 240 fps, but the picture quality has to be reduced somewhat. 120 or 240 will do a pretty good job of slowing down a golf swing, but the speeding golf ball itself will be blurred."
This statement is a little misleading at the end (only). Blur and frame rate have nothing to do with each other. Like in conventional photography, blur depends on shutter speed, period. Think of frame rate as the number of pictures per second. Each picture will not be blurred if 1. nothing is moving or 2. something is moving but the shutter speed is relatively fast. Blur has nothing to do with how many pictures you take or how fast you take them (except you cannot use too slow a shutter speed if the frame rate is slowed). If you want less blur, shoot at a faster shutter speed. With me so far? Well, for regular video, you actually want blur; we see fast motion blurred with our eyes, so in video having moving objects slightly blurred makes for smooth looking video. But for slow mo, you want less blur. So, for regular-speed video you shoot at 1/60th of a second (60 fps frame rate); for slo-mo, a shutter speed faster than that, maybe 1/125th or faster. The camera will choose a faster shutter speed for you, if it is an FZ200.
Now, let's say you have the FZ200, as I do. It makes life really easy.
Shoot regular video at 108060p (that is 60 fps) to get the highest quality (1/60th of s second shutter for smooth motion) HD video. And, as Bill, said, you can slow that 60 fps video down to a less rapid frame rate (say, 30 fps) to get slo-mo, but that takes work in an editor. Forget that, given you are in kindergarten.
The camera provides an alternative to regular speed (it also has other options for regular speed, of 30 fps). You can have it shoot video at 1280x720 resolution at a frame rate of 120 fps and then *in the camera* it automatically creates a 1280x720 video at 30 fps. - a 1/4-speed video, real slo-mo. It is HD, it looks ok. Nothing to do with blur.
In an editor, you can combine the regular video, shot at 108060p, with the slo-mo video 72030p and output all of it at 72030p and you will have both regular motion and then slow motion all at 1280x720 resolution (HD). Converting a 108060p video to a 72030p video does not create slo-mo. To get slo mo from regular mo video, you have to do more than convert the frame rate, you have to stretch the video in time too. As I said, too much work. Use the camera to take and make slo-mo and regular mo. [what is confusing is that the slo-mo modes are called high-speed!] But just pay attention to what I said: 60 fps for regular speed, 120 fps for slo mo (yes there is also 240 fps, but that is at a very low resolution that does not mix well with HD regular-speed video).
If this is confusing, read a book on video, take a course, watch an instructional video (in regular mo). Or, better, just get the camera and try out the modes and watch and learn from what you shot. And then when you like what you got, post it here. We talk too much, and take and see too little video.
