FLUX 3 Video — the verdict: Developers and agencies who need video with synced audio and dialogue in one generation call FLUX 3 Video's real pitch is skipping a step other pipelines force on you: generating a talking, scored clip in one call instead of rendering silent video and bolting on a voice model afterward.

Overview
FLUX 3 Video is Black Forest Labs' text-to-video and image-to-video model, generating cinematic clips up to 20 seconds in HD or Full HD with native audio, dialogue, and lip-syncing baked into the same generation pass, so you're not stitching a silent clip together with a separate voice tool afterward. It reached general availability on August 4, 2026 via the BFL API and select partner integrations. Multi-shot generation produces several scenes or camera angles from one prompt, Video Continuation extends an existing clip by up to 4 more seconds, and a cheap Draft Mode renders fast low-cost previews so you're not paying full price to find out a prompt didn't work.
Dialogue and lip-sync run in 15+ languages. Pricing is pay-as-you-go with no subscription: Draft HD runs $0.06 per second, Standard HD $0.17 per second, and Standard Full HD $0.29 per second, with volume discounts for enterprise usage. There's no dedicated consumer app yet, access is API-only, which puts it squarely in developer and agency territory rather than a drop-in replacement for a point-and-click video generator.
Our Take
FLUX 3 Video's real pitch is skipping a step other pipelines force on you: generating a talking, scored clip in one call instead of rendering silent video and bolting on a voice model afterward. Draft Mode is the detail that matters for anyone paying per second, it makes iterating on a prompt cheap before you commit to a full-quality render. The catch is that this ships API-only at launch, so it's built for developers and agencies wiring it into a pipeline, not someone who wants a consumer app to click around in. If that's your setup, it's worth evaluating against Runway and Luma on cost per finished second, not just quality.
