What is FPS?
| Frames Per Second |
|
FPS stands for frames per second in which the measurement of a video clip contains number of image frames within one second. In general, if you want to store all video at 30 frames per second (30 FPS) as opposed to 1 FPS, then that requires 30 times the amount of storage. A unit of measurement used when dealing with video. Each frame is a picture. The frames per second indicate how many times the picture will be changed per second. When using a web-camera, the transmission rate is usually 15 frames per second. TVs use 25-30 frames per second, providing a very good quality picture. Flash Player: FPS, or frames per second, is the setting in Flash that dictates to the Flash player how fast to play back a movie. The default setting is 12, meaning that each frame is displayed on-screen for one twelfth of a second. FPS can be set from 0.01 to 120, causing frames to be displayed at the rate of as little as 1 frame every hundred seconds to as many as 120 frames in a single second. in theory, anyway. In reality, most experienced Flash developers will at some point have created a movie on their sweet developer box and then cringed as they watched it trickle along on a p90 or a 604 132. the problem is that their own machine plays the movie back at a different frame rate than the slower machine. Why? because in Flash the FPS setting doesn't actually stay the same between different machines. FPS is like a speed limit: you can tell a movie not to play faster than the specified FPS, and all machines will obey, but you can't tell a movie to stay above a certain frame rate. If a machine doesn't have the processing power to render the frames at the specified FPS, the movie will simply run more slowly. so, the question for developers has always been *how much slower*? |
