Catalog preview for FLUX.3 Video. Review your own result before publishing.
A starting point.
Select the operation for your source, upload any required media, and describe the result you want.
Before you publish.
Watch the entire clip and compare motion, identity, transitions and audio with your inputs.
Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.
Inputs and settings
Choose 5–20 seconds, or auto where offered. Auto reserves for up to 20 seconds; final settlement uses provider-reported billing.
Draft modes generate a 720p clip. Full generation offers 720p or 1080p. For keyframes, use unique frame_index values within duration × 24; up to ten keyframes are supported.
Upload an MP4 source smaller than 50 MB and shorter than 15 seconds.

Check the current model schema for supported inputs and options. Other tasks may use different model IDs.
From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
