}'8 fields in input, required first.
promptRequiredText prompt for video generation
prompt_expansion_modeRequiredHow much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'balanced' returns in about a second. 'quality' spends up to ~30s on a richer prompt.
seedOptionalRandom seed. A random seed is selected when omitted.
durationOptionalVideo length in seconds. The output can run up to about 0.7 s longer than requested. Use at least 2 s with target_audio_url.
image_urlOptional
$0.34/sFLUX 3 Image-to-Video animates a required reference image into a 5-20 second video, preserving subject appearance while using prompt control to guide motion, camera movement, visual style, and optional synchronized audio at 720P / 1080P output.
$0.06/sGemini Omni 1.1 Flash Image-to-Video animates a start image into short AI videos, optionally targeting an end frame and generating synchronized audio at resolutions from 360P to 4K for social content, creative storytelling, marketing videos, and production workflows.
$0.06/sGemini Omni 1.1 Flash Reference-to-Video creates short AI videos with synchronized audio from a text prompt plus optional image and video references, supporting resolutions from 360P to 4K for character-consistent clips, visual reference guidance, social content, marketing videos, and production workflows.
from $2.80Kandinsky 6.0 Pro turns a start frame into a high-resolution, cinematic video clip with controllable motion and strong visual fidelity.

Optional URL of the image to use as the first frame. When provided, the output canvas follows this image. If only end_image_url is provided, the canvas follows that last frame instead. If both images are omitted, the request is handled as text-to-video (16:9 by default).
resolutionOptionalThe native generation resolution, or 1080P latent refinement from a native 768P source.
end_image_urlOptionalOptional URL of the image to use as the last frame. It may be provided alone for end-only keyframe generation; in that case the output canvas follows this image.
target_audio_urlOptionalOptional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the generated video's length, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data URI.
