Filmmaking Dictionary: Number 5 / 59.94 fps
Definition
59.94 fps is the conventional rounded label for 60,000/1,001 frames per second, approximately 59.94006 fps. It belongs to the fractional-rate family used in many video workflows alongside 29.97 and 23.976 fps.
A camera or monitor may shorten the label to ’60’ in some menus, so the technical recording mode matters more than the casual name. True 60 fps and 59.94 fps are close, but they are not identical timing standards.
Progressive Frames Versus Interlaced Fields
In 59.94p, the signal contains about 59.94 complete progressive frames each second. In a conventional signal described as 59.94i, that number commonly refers to fields, with approximately 29.97 frame periods each second. Documentation sometimes uses different interlaced naming conventions, making the full specification essential.
A fifty-nine-point-nine-four field rate does not mean the source contains the same complete pictures as 59.94p. Treating the formats as interchangeable can create motion, deinterlacing and export problems.
Camera reports should record the exact rate and scanning format. That information helps the editor distinguish intentional slow motion from a setting mismatch when several cameras or external recorders contribute footage.

Working with the Rate
- Match camera, recorder and project settings to the intended delivery specification.
- Confirm whether the signal is progressive or interlaced.
- Check whether audio remains synchronized when footage is conformed to a different playback rate.
- Use appropriate conversion when mixing true 60 fps with fractional-rate footage.
Slow-Motion Example
Playing a 59.94 fps recording at 29.97 fps produces half-speed motion because the rates have an exact two-to-one relationship. Conforming it to 23.976 fps produces 40% speed. This uses the captured frames at a slower playback rate rather than generating intermediate images.
For real-time coverage, simply interpreting 59.94 footage as true 60 changes its running time slightly. That difference becomes more noticeable over long recordings or when matching separately recorded audio. A deliberate conversion workflow prevents small timing assumptions from becoming synchronization problems.

Frequently Asked Questions
Does drop-frame timecode remove video frames?
No. Drop-frame timecode adjusts frame-number labels to keep timecode closer to clock time. It does not discard recorded pictures.
Is 59.94 fps only useful for slow motion?
No. It can also be the normal capture and delivery rate for smooth-motion coverage. The playback specification determines whether the footage is real time or slowed.
