XIII Some digital video formats actually support several frame rates within a single format, allowing variable frame rate video recording and film (24 fps) compatibility. Frame rate 24 23.98 (23.976) 25 29.97 30 50 59.94 60 Media Description Film; high definition video This is the universally accepted film frame rate. Movie theaters worldwide almost always use this frame rate. Many high definition formats can record and play back video at this rate, though 23.98 is usually chosen instead (see below). Film; high definition video with NTSC compatibility; NTSC This is 24 fps slowed down by 99.9% (1000/1001) to easily transfer film to NTSC video. Many high definition video formats (and some SD formats) can record at this speed, and it is usually preferred over true 24 fps because of NTSC compatibility. PAL; high definition video The European video standard. Film is sometimes shot at 25 fps when destined for editing or distribution on PAL video. NTSC; high definition video This has been the color NTSC video standard since 1953. This number is sometimes inaccurately referred to as 30 fps. High definition video; early black-and-white NTSC video Some high definition cameras can record at 30 fps, as opposed to 29.97 fps. Before color was added to NTSC video signals, the frame rate was truly 30 fps. However, this format is almost never used today. PAL; high definition video This refers to the interlaced field rate (double the frame rate) of PAL. Some 1080i high definition cameras can record at this frame rate. High definition video High definition cameras can record at this frame with NTSC compatibility rate, which is compatible with NTSC video. It is also the interlaced field rate of NTSC video. This number is sometimes referred to as 60 fps, but it is best to use 59.94 fps unless you really mean 60. High definition video High definition equipment can often play and record at this frame rate, but 59.94 fps is much more common because of NTSC compatibility. Important: Many people round 29.97 fps to 30 fps, but this can lead to confusion during post-production. Today, it is still very rare to use a frame rate of 30 fps, but very common to use 29.97 fps. When in doubt, ask people to clarify whether they really mean 30 fps, or if they are simply rounding 29.97 fps for convenience. Appendix B Frame Rate and Timecode 1051

Appendix B

Frame Rate and Timecode

1051

XIII

Some digital video formats actually support several frame rates within a single format,

allowing variable frame rate video recording and film (24 fps) compatibility.

Important:

Many people round 29.97 fps to 30 fps, but this can lead to confusion

during post-production. Today, it is still very rare to use a frame rate of 30 fps, but very

common to use 29.97 fps. When in doubt, ask people to clarify whether they really

mean 30 fps, or if they are simply rounding 29.97 fps for convenience.

Frame rate

Media

Description

Film; high definition

video

This is the universally accepted film frame rate.

Movie theaters worldwide almost always use this

frame rate. Many high definition formats can

record and play back video at this rate, though

23.98 is usually chosen instead (see below).

23.98

(23.976)

Film; high definition

video with NTSC

compatibility; NTSC

This is 24 fps slowed down by 99.9% (1000/1001)

to easily transfer film to NTSC video. Many high

definition video formats (and some SD formats)

can record at this speed, and it is usually

preferred over true 24 fps because of NTSC

compatibility.

PAL; high definition

video

The European video standard. Film is sometimes

shot at 25 fps when destined for editing or

distribution on PAL video.

29.97

NTSC; high definition

video

This has been the color NTSC video standard

since 1953. This number is sometimes inaccurately

referred to as 30 fps.

High definition video;

early black-and-white

NTSC video

Some high definition cameras can record at

30 fps, as opposed to 29.97 fps. Before color was

added to NTSC video signals, the frame rate was

truly 30 fps. However, this format is almost never

used today.

PAL; high definition

video

This refers to the interlaced field rate (double the

frame rate) of PAL. Some 1080i high definition

cameras can record at this frame rate.

59.94

High definition video

with NTSC compatibility

High definition cameras can record at this frame

rate, which is compatible with NTSC video. It is

also the interlaced field rate of NTSC video. This

number is sometimes referred to as 60 fps, but it

is best to use 59.94 fps unless you really mean 60.

High definition video

High definition equipment can often play and

record at this frame rate, but 59.94 fps is much

more common because of NTSC compatibility.
