The frame rate is the number of images distributed in one second. A "50p" or "XXXXp50" video stream contains 50 images per second (frames per second, fps). With interlaced video the 50 frames are actually only half frames with every alternative number of lines.
One second equals 1000 msec, a video stream with a frame rate of 50 fps carries five images in 100 msec (a 1/10th of one second).
50 progressive frames per second (Europe) each frame containing a full image |
50 interlaced frames per second (Europe) each frame containing a half image with every second line |
60 progressive frames per second (US) each frame containing a full image |
60 interlaced frames per second (US) each frame containing a half image with every second line |
25 progressive frames per second (Europe) each frame containing a full image |
24 interlaced frames per second (Movie Format) each frame containing a full image |
25psF progressive segmented frames - 25 progressive frames, transported as 'interlaced' fields each frame with two fields from identical time slot |
24psF progressive segmented frames - 24 progressive frames, transported as 'interlaced' fields each frame with two fields from identical time slot |
24 movie frames with a double shutter to create 48 images per second | 24 movie frames with a triple shutter to create 72 images per second |
The generally used term for the video format with 25 frames (full images) containing each two fields (half images) was/is "i50" or "i60". For "i50" it meant 25 frames with 50 fields, the number "50" corresponded with the number of transmitted images (full images, frames, or half images, fields). A progressive format with 50 full images (frames) is "p50", the number "50" again corresponded with the number of transmitted images (full images, frames, or half images, fields)
In contrast to the format "i50" (with 25 frames and 50 fields) a progressive format with 25 frames that transports these 25 frames via 50 fields, the "psf" format (progressive segmented frames), is called "psf25". Actually both formats "i50" and "psf25" are 100% identical on the transport stream. The only difference is that the fields in the interlaced video (i50) are recorded at different times, one after the other, and in the psf format each two fields are generated from one progressive frame, recorded at the same time.
The number 50 and the number 25 in "i50" and "psf25" mean the same !
The EBU (European Broadcasting Union) defines:
a format with 25 frames and 50 fields (interlaced): | i/25 |
a format with 25 frames (progressive): | p/25 |
a format with 50 frames (progressive): | p/50 |
