Frame interpolation generates the frames between the ones you shot. Choppy footage plays smoothly, and a slowed clip becomes proper slow motion instead of a slideshow.
Synthesized in-betweens, not cross-fades
Cross-fading neighbouring frames produces ghosting. Interpolation instead tracks how pixels move between frames and renders new frames along that motion: one, two or four per gap, as you choose.
Choose 1, 2 or 4 new frames per gap
Motion-aware synthesis, not cross-fade ghosting
Great on AI generations, which often render at low frame rates
Slow motion that was never shot
Slow a 24 fps clip to quarter speed and you are watching six frames a second, which reads as a slideshow. Interpolate first and the stretch has frames to spend, so the motion stays continuous all the way down.
2×–4× slow motion from ordinary footage
No strobing, because the synthesized frames carry the motion through
The output is a normal clip: trim it, grade it, cut it
Questions
How many frames can interpolation add?
One, two or four synthesized frames per gap, which is enough to smooth a 16–24 fps source or to hold up a 2×–4× slow-motion stretch.
Is it as good as shooting high-speed?
High-frame-rate capture is still better when you can shoot it. Interpolation is for footage you already have, and very fast or erratic motion is where synthesized frames struggle.
Why do AI clips benefit so much?
Many video models render at 16–24 fps to keep generation fast. One interpolation pass makes those clips play like native footage.
How is frame interpolation priced?
By source duration and how many frames you add per gap, with the token price quoted before the run.
