Topaz Apollo

VIDEOtopaz-apollo-interpolate-video

Apollo is Topaz Labs’ general-purpose frame interpolation model. It generates intermediate frames to retime footage up to 120fps, or to stretch it into slow motion, leaving resolution untouched. Start here unless the motion is unusually fast or complex.

object
target_fps
Target frame rate

Frames generated in between the source’s own. Resolution is unchanged.

integer
default: 30 >= 16 <= 120 multiple of 1
slowdown_factor
Slow motion

Stretch the clip to this many times its length. Cost scales with it.

integer
default: 1 >= 1 <= 8 multiple of 1
video_codec
Codec

Advanced field.

string
default: H265
Allowed values: H265 H264
guidance_file_init_video
Source video

The video to modify

Array<object>
InferenceFormFileRef

A single guidance/reference file supplied to a reference_image_list field.

The slot’s guidance type is fixed by the field it’s attached to; the caller supplies the file URL and, where the model supports per-file weighting, a weight.
