FLUX 3 Video API Limits, Inputs and Production Checks on APIMART

The public APIMART description states: Use the FLUX 3 Video API for text-to-video, ordered image keyframes, video continuation, synchronized audio, and 5–20 second HD or FHD clips.

Source-backed production checks

What is FLUX 3 Video? FLUX 3 Video is Black Forest Labs' video model for text-to-video, ordered image keyframes, video continuation, and draft enhancement with optional synchronized native audio.
What can FLUX 3 Video generate? It supports text-to-video, image-to-video with ordered keyframes, video continuation, and enhancement of a completed draft task.
Does FLUX 3 Video generate audio? Yes. Synchronized native audio is enabled by default. Set audio to false when you need a silent video; disabling audio does not change the price.

Validate every request field against the linked API reference. Persist task identifiers for asynchronous routes, use bounded polling and backoff, and do not count submission as completed output.
