Can AI make your own footage look smoother in slow motion?
I tested Runway’s new Enhance Frame Rate feature on three different types of motion: walking, a skateboard trick, and a passing tram.
Left: manually slowed down Right: enhanced to 120fps, then slowed down
After putting them side by side, the difference is subtle but the slow motion does look smoother, especially with faster movements.
I did notice some distortion in the last scene, though, so it’s not perfect yet.
Still, it’s a useful tool when you want to slow down footage and emphasize the movement.
Can you tell the difference?

High slow motion is better in high frames nice animation I like how clothes are flying by the air ❤️❤️

keeping the distorted clip in is the honest move

Great breakdown of the frame rate comparison. It’s interesting how AI handles fast movements versus subtle ones, though minor distortions are expected at this stage.

Thank you! Agreed, hopefully it'll improve over time!

Testing it across walking, a skate trick, and a tram is a smart way to expose where interpolation breaks, fast motion is always the tell. Enhancing to 120fps then slowing is a clever pipeline, the smoothness on the everyday footage is genuinely impressive. Great side-by-side.

Thank you Aditya! Glad you like it! Yes it's perfect for emphasizing the movement!

that second one with the skateboard is stellar!

The skateboard clip shows the difference best. Faster motion is where 120fps really earns it, the walking one is pretty close either way.
