24p

In video technology, 24p refers to a video format that operates at a 24 frames per second frame rate with progressive scanning (not interlaced). Originally, 24p was used in the non-linear editing of film-originated material. Today, 24p formats are being increasingly used for aesthetic reasons in digital image acquisition, delivering film-like motion characteristics. Some vendors advertise 24p products as a cheaper alternative to film acquisition. When working entirely within the digital non-linear domain, 24p material is more easily handled than material of higher frame rates. 24p material requires care when it is processed using equipment designed for standard video frame rates. There are two common workflows for processing 24p material using video equipment, one using PAL frame rates, and the other using NTSC frame rates. Of these two, the PAL route is the simpler, but each has its own complications.

Disadvantages

In general, 24 frames-per-second video has more trouble with fast camera motion than other, higher frame rates, sometimes showing a "strobe" or "choppy" motion, just like film will if shot as if it is video, without slower camera panning and zooming motion. It is therefore not well-suited for programming requiring spontaneous camera action or "reality" camerawork. Nevertheless, effective "smoothing" high frame rate upscalers were created; the latest generation of those on AI do not introduce artifacts in frames.

Future

Digital cinema equipment is now capable of handling much higher frame rates, such as 48p, 60p and 120p frame rates even in 3D, along with the traditional 24p. 3D in Blu-ray is still only 24p max. 48p has twice the motion resolution of 24p, but also requires more bandwidth, data storage, and potentially illumination level. Peter Jackson's three part film The Hobbit is a production that makes use of the 48p frame rate, but 48p was never used on Blu-ray or streaming platforms, only in cinemas. Other movies, however, have been released at higher framerates on Blu-ray (such as Billy Lynn's Long Halftime Walk). Some current, best-of-breed professional video cameras provide progressive capture, which is 5 times 24p and can be converted to 24p, 30p, 50i, and 60i/p with editing options and precision in motion shots.
