https://api.segmind.com/v1/flux-3-max-image-to-videoParameters
imagerequiredstring (uri)First frame of the video (PNG, JPEG or WebP).
promptrequiredstringDescribe how the video unfolds from the image: motion, camera and sound.
"The camera pushes in slowly as the subject turns toward the light; gentle wind moves through the scene and soft ambient sound rises."aspect_ratiooptionalstring'auto' follows the image's aspect ratio.
"auto""auto""21:9""2:1""16:9""4:3""1:1""3:4""9:16"durationoptionalintegerLength of the video, 5 to 20 seconds. Billed per second of output.
5Range: 5 - 20generate_audiooptionalbooleanNative synchronized audio. Off for a silent clip.
truelast_frame_imageoptionalstring (uri)Optional last frame; the model interpolates from the first image to this one.
reasoning_leveloptionalstringHow much the model reasons about the prompt before rendering. 'low' is faster.
"high""low""high"resolutionoptionalstringOutput resolution. 1080p costs more per second than 720p.
"720p""720p""1080p"seedoptionalintegerSeed for reproducible generation. -1 for random.
-1Range: -1 - 999999999999999Response Type
Returns: Video
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/flux-3-max-image-to-videoSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
Common Error Codes
The API returns standard HTTP status codes. Detailed error messages are provided in the response body.
