FLUX 3 Video - Oxen.ai

Try FLUX 3 Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: flux-3-video FLUX 3 Video generates video from a text prompt, from keyframes, or by continuing an existing clip, served directly by Black Forest Labs. Clips run 5 to 20 seconds at 720p or 1080p, with synchronized audio generated by default. Supply keyframes to animate stills, or a source clip to continue it; with neither, it generates from the prompt alone. Draft mode trades quality for a lower per-second rate and is useful for iterating before a full generation.

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.

Request parameters

Required parameters

Field	Type	Default	Description
`prompt`	`string`	—	Free-form prompt describing the video.

Optional parameters

Field	Type	Default	Description
`input_images`	`array<string>`	—	Images that become frames of the generated video, 1 to 10 in order: one image starts the video, two start and end it, and beyond that the first starts it, the last ends it, and the rest fall evenly in between. They are frames, not references, so the prompt cannot cite them. Leave empty to generate from the prompt alone. Cannot be combined with Continue From Video.
`input_video`	`string`	—	Clip to extend; the generated video carries on from its final frames. MP4. Cannot be combined with Keyframes. Billed at a higher per-second rate than generating from a prompt or keyframes. Format: uri.
`resolution`	`string`	`"720p"`	Output resolution. 1080p costs more per second. One of: 720p, 1080p.
`aspect_ratio`	`string`	`"auto"`	Aspect ratio of the generated video. Auto lets the model choose. One of: auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, 9:16.
`duration`	`integer`	`5`	Duration in seconds. One of: 5, 6, 7, 8, 9, 10, 12, 15, 18, 20.
`generate_audio`	`boolean`	`true`	Generate synchronized audio for the video.
`draft`	`boolean`	`false`	Draft mode: rapid, cost-effective exploration at a lower per-second rate. HD only.
`safety_tolerance`	`integer`	`2`	Safety filter strictness, 0 is strictest. One of: 0, 1, 2, 3, 4.
