Rate and duration together decide how many frames the model actually has to produce. Ten seconds at 60fps is six hundred frames against two hundred and forty at 24fps, and every one of them has to agree with its neighbours. That is why higher frame rates cost more time and are not offered everywhere.
The choice reads on screen. 24fps carries the slight strobe audiences associate with cinema; 60fps looks immediate and hyper-real, which flatters sport and gameplay and makes drama look like a home video. Neither is a quality setting — they are different textures of motion.
Some models generate at a fixed internal rate and interpolate to whatever you asked for. That is not the same as generating those frames, and it is worth knowing which one you are getting when smoothness is the point.
In practice
- 24 or 30 is the safe default for social; 60 is worth it only when the motion is fast.
- Mixing rates in one edit causes judder at the joins — pick one for the whole piece.
- Slow motion needs a high capture rate, not a high playback rate.

The mistake to avoid
Assuming a higher number is a higher quality. At a fixed budget, more frames per second usually means fewer pixels or less time per frame.
Related terms
Frame interpolation
Frame interpolation invents new frames between existing ones, raising a clip's frame rate or slowing it down without it becoming choppy.
Duration
Duration meaning: how long a generated clip runs, chosen before generation from the lengths the model supports, not trimmed after.
Resolution
Resolution is how many pixels an output contains, usually named by its height — 720p, 1080p, 4K — and set before generation rather than after.
Temporal consistency
Temporal consistency means staying stable over time; in video, each frame agrees with the one before, so nothing flickers, shimmers or drifts as it plays.
Seed
Seed meaning: the number that sets the random starting noise so the same seed and settings can reproduce the same output.
