About FILM · Video

Takes a video through `video_url` and generates new frames between existing ones, using FILM, which is designed for large motion. `num_frames` sets how many frames are added (1 to 4). Scene detection can split the video to avoid smeared frames at cuts, and `loop` blends the end back to the start. Output frame rate is calculated automatically or set with `fps` (1 to 60), with `video_quality` and `video_write_mode` options.

Parameters

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

NameType DefaultAllowed Description
video_urlrequired video
Typeurl · video
URL pointing to the video used for interpolation.
num_framesoptional
Typeinteger
Default1
1 – 4
Count of new frames generated between frames of the input video.
use_scene_detectionoptional
Typeboolean
Defaultfalse
Scene-boundary handling for interpolation: False keeps the whole video together as one scene, whereas True detects scenes and splits them before interpolation. Splitting eliminates smeared transition frames, though inaccurate detection can introduce false positives.
use_calculated_fpsoptional
Typeboolean
Defaulttrue
Output frame-rate source: the supplied FPS applies with False, while True overrides it with the calculated input-video FPS multiplied by the frame count.
fpsoptional
Typeinteger
Default8
1 – 60
Frame rate setting used only with use_calculated_fps set to False, specifying how many frames the output video plays per second.
loopoptional
Typeboolean
Defaultfalse
Control whether playback forms a seamless loop by returning from the final frame to the first: True enables this return, and False leaves it disabled.
video_qualityoptional
Typeenum
Defaulthigh
lowmediumhighmaximum
Video quality selection used exclusively with 'video' as the output_type.
video_write_modeoptional
Typeenum
Defaultbalanced
fastbalancedsmall
Video writing mode used exclusively with 'video' as the output_type.
enable_safety_checkeroptional
Typeboolean
Defaulttrue
Screening can be relaxed by setting false, provided the caller is authorized.
required Canonical name, also accepted

File parameters take a public https:// URL, a data: URI up to 10 MB, or the file_url of an upload. Files
