What Is 24p Video?
The term 24p refers to 24 fps, progressive scan video. For film, this is nothing unusual,
but for video, both progressive scanning and the 24 fps frame rate are still exciting new
territory. Instead of building 24 fps video cameras that would be incompatible with
established NTSC and PAL video equipment, some new camcorders make it possible to
shoot 24p video while maintaining backward compatibility with NTSC or PAL equipment.
One of the obvious reasons to shoot 24p video is to make it easy to transfer your video
to film without any frame rate conversions. Another reason is to achieve a “film look” on
video, even though film was never used. 24p video is also a convenient starting format
for moving between NTSC video, PAL video, and film.
