The evolution of IP video has placed a lot of attention on the resolution of video, as measured in the growing number of pixels in a frame.
But another variable, receiving less attention, is the number of frames captured per minute (fps). We inherited the idea of “full-frame-rate” video from the analogue world, but increasing numbers of pixels (and more data!) have sometimes led to use of slower frame rates. We asked our Expert Panel: What is the value of “full-frame-rate” video? Absent specific compliance requirements, what might suffice as an acceptable frame rate (i.e., less than 30 frames per second [NTSC] or 25 frames per second [PAL])?
