Black Forest Labs releases FLUX 3 Video generally available — 20-second HD clips with native audio and lip sync in 14+ languages. What HK creators need to know.
Black Forest Labs (BFL), the team behind the popular FLUX image models, just made FLUX 3 Video generally available. It's a major video generation model that produces up to 20-second HD and Full HD clips with built-in audio — dialogue, sound effects, and ambient noise all generated in one pass. For Hong Kong video creators, this is the kind of leap that changes production workflows overnight.
What FLUX 3 Video Can Do
FLUX 3 Video supports text-to-video, image-to-video, and video-to-video generation with keyframe control and video continuation. It handles multiple scenes and camera angles within a single clip, renders typography directly in scenes, and follows complex multi-part prompts with surprising accuracy. But the standout feature is native audio generation — including lip-synced dialogue in over 14 languages. That means Cantonese, Mandarin, and English are all on the table.
BFL's internal benchmarks put FLUX 3 Video at the top of the Elo rankings: 1,135 for text-to-video and 1,051 for image-to-video, ahead of Gemini Omni Flash, MiniMax H3, and Seedance 2.0.
Pricing That Makes Sense for Production
FLUX 3 Video pricing is per-second with four quality tiers. Draft HD costs $0.06 per second for text-to-video or image-to-video, and $0.12 for video-to-video. Full quality HD costs $0.17 per second for text-to-video or image-to-video, and $0.41 for video-to-video. Full HD costs $0.29 and $0.53 per second respectively. Audio is included at all tiers.
At full quality, a 10-second HD clip costs $1.70 — competitive with other top-tier video models, especially considering you get native audio and lip sync in the same output.
What This Means for Hong Kong Creators
FLUX 3 Video solves two chronic problems for HK video production teams. First, native audio eliminates the post-production step of syncing voiceovers or sound design to AI video — everything comes out of the model already matched. Second, the 14+ language lip sync support is a game-changer for the bilingual ad campaigns common in Hong Kong, where brands often produce the same spot in Cantonese, Mandarin, and English simultaneously.
Agencies serving clients like HSBC or the Hong Kong Tourism Board can generate a 15-second adspot with proper lip sync in three languages in the time it used to take to render a single silent clip. That's not just faster — it's a fundamentally different production capability.
How Cooly Studio Fits In
Cooly Studio already supports multiple leading video models, and FLUX 3 Video slots naturally into an AI-first production pipeline. Whether you are generating storyboards, client pitch decks, or finished ad content, having access to a model that outputs audio-synced video in one pass cuts iteration time significantly.
