慢动作 / 补帧

Half the speed. Twice the frames.

Generated video comes out at 24 fps. Interpolation synthesises the frames between, so you can slow a moment to half speed or deliver buttery 60 fps — without the strobing of a plain speed change.

24 帧变 60 帧，或者干净的半速慢动作，没有拖影。

FAQ

Short answers.

Will it blur?

Interpolation models predict motion; they avoid the ghosting of a frame blend but very fast motion can still soften.

Can I combine with upscaling?

Yes — the same enhance pass can upscale and interpolate.

Is audio preserved?

For slow motion, audio is stretched or dropped depending on the model.
