The following guide offers a solution on how to change Frame Rate of video MP4, AVI, MOV, WMV, MKV, FLV, ASF, etc with a powerful Frame Rate Converter. Some 3D video use double fps to alternately display two images for two eyes. Video surveillance and video conference usually use lower fps. Higher frame rate consumes more disk space, but looks more smooth. Lower frame rate consumes less disk space, but looks jerky. When playing movies on NTSC television, it needs a process named telecine or pulldown to convert 24 fps movie to 29.97.įor computer video files, any frame rate will be OK. The standard film cameras projection speed is 24 fps. PAL, used primarily in Europe, uses 25 fps based on 50 Hz electrical mains. NTSC in North America uses 30 fps (now adjusted to 29.97 fps for color NTSC) based on 60 Hz electrical power. The more frames recorded per second, the more accurately motion is documented onto the recording medium.Įarly television systems selected frame rates based on local electrical standards to avoid electrical interference with the picture.

Frame rate is measured in frames per second (fps). In motion pictures, television, and in computer video displays, the frame rate is the number of unique consecutive frames or images that are projected or displayed per second. Feb 23, 2015, Posted by Shirley White What Is Frame Rate?
