FLUX 3 Video: native audio, keyframes and Draft mode

Use current availability, not only the launch post

BFL introduced FLUX 3 on July 23, 2026 with a staged rollout. Its product page checked on September 20 describes Video access through the dashboard and API, including text, image and video inputs, editing, continuation and keyframes.

The page lists single generations up to 20 seconds and resolution bands from HD through UHD/4K, defined by pixels per frame. Image, Action and Dev weights are separate parts of the rollout; Video availability does not establish universal access to them.

Validate direction in Draft mode

BFL describes a faster, lower-cost HD Draft path and enhancement to full-quality FHD. Use it to inspect movement and framing before committing to a final render. Check current official pricing rather than treating an article as a permanent quote.

Specify sound independently

A fixed camera watches a ceramic cup in a quiet cafe. A server gently places it on a wooden table, producing a short contact sound. Light rain is audible outside. No dialogue or music. Natural finger contact and no scene cuts.

Make keyframes physically compatible

Align subject identity, perspective and plausible motion between reference frames. Large unexplained differences in clothing, product structure or camera position make transitions harder. Inspect the whole clip and audio track, not only its best still frame.
