Filmizing is a process that makes video productions seem to have been shot on film. The process is usually electronic, although filmizing can sometimes occur as an un-intentional by-product of some optical techniques, such as telerecording.
Today, most digital cinematography video cameras in use feature 24p format (24 progressive frames per second).
When shooting with old cameras, 50 Hz interlaced video (usually used with most forms of PAL and SECAM) can be relatively easily processed to give 25 progressive frames]] per second, which is the framerate that the PAL/SECAM telecine process also uses. Every two video fields can be "blended" together, every other field can be decimated and the remaining fields can be shown for double the length (this noticeably reduces vertical resolution), or a motion estimation process can be applied to achieve one frame out of every two fields. This technique is sometimes called Field-removed video or FRV. Some modern PAL video cameras do offer the ability to produce 25 frame-per-second progressive video, negating the requirement of post-processing the video to get a temporal similarity to film.
