Any suggestions? It doesnât have to be the greatest HD video i just want a simple video that i can carry with me throughout the day that would hopefully last at least 6-8 hours. The ones that ive found all generally have 2.5 hour capabilities. Since im traveling A LOT throughout the day and using my bike i would like a little extra protection, especially going through some rough areas of the city to get to class with my laptop, and phone in my book bag. So id preferably like for this camera to be as discreet as possible, i donât mind having a wire connecting to the battery pack or something like that, i can easily hide that in my helmet or bag. I found the POV.HD systems a while ago but theyâve been out of stock for about a year so Iâm not too optimistic theyâll have what i need any time soon. So any advice of a fairly small camera with a large charge for long time video recording?

Is there a difference between shutter speed and frames per second?

I am thinking of buying a Sony DCR VX2100. This is my first good video camera I have ever purchased. It has a10,000th of a second shutter speed. Does that mean 10,000 frames per second? If its not, how can I find out the FPS on the camera. I'll be using it for extreme sports so I need to be able to have a very smooth slow motion. Thanks to anyone who can help.
Answer
The frame rate is the number of frames the camera takes in a second.
The shutter speed is the amount of time it takes for the camera to take each frame.
Television frame rates are standardized, and will remain the same if you change the shutter speed. NTSC-format video runs at 29.97 fps, and PAL and SECAM-format video run at 25 fps. It depends on what part of the world you're working in. There are also HD formats at different frame rates. The DCR-VX2100 only shoots standard-definition video, so it will shoot at one of those two frame rates, depending on where you are.
Again, frames per second is the number of pictures the camera takes in a second. Shutter speed is how quickly the camera takes each picture. So, let's say you're in an NTSC-format country. You decide to shoot with a 1/100 shutter speed. The camera will shoot 29.97 frames every second, and every frame will be shot in 1/100th of a second. In other words, the "shutter" will "open" for 1/100th of a second to shoot each frame. It will do this 29.97 times every second.
At faster shutter speeds (1/250, 1/500, etc.), the camera still shoots 29.97 frames every second, but it opens the shutter for 1/250th or 1/500th of a second for every frame it shoots.
Faster shutter speeds are good for action shots, such as sports. You get less motion blur at faster shutter speeds, but you need more light because of the short amounts of time the shutter opens to let light in.
In short, frame rates won't change unless you're willing to invest thousands more for specialty super-slow-mo cameras that are sometimes used at professional sporting events or on shows like "MythBusters" that are taping things like bullets and explosions. Still, you should be able to get smooth slow-motion at standard frame rates if you use good editing software.
