Video URL for retiming or frame interpolation.

model default Apollo

Frame-interpolation model selection based on motion: use Aion for extreme or complex motion, Chronos for real-world motion, or Apollo for general purposes.

default 60

Frame rate, in frames per second, of the interpolated result.

default 1

Slow-motion multiplier, capped at 8x: output duration scales by this factor while using the target FPS. A value of 2 gives 2x slow motion; use 1 for unchanged playback speed.

About Topaz Interpolate Video

Retimes an existing video by generating in-between frames. Pick the `model`: Apollo for general use, Chronos for real-world motion, Aion for extreme or complex motion. `target_fps` ranges from 16 to 120, and `slowdown_factor` from 1 to 8 stretches the clip into slow motion. Output is H265 by default, with an H264 switch.

Parameters

Send either the canonical name or the native name, not both. Canonical names
