● Questions
Frequently asked questions
FLUX 3 is free to try. A new account gets ⚡50 on signup with no card. Video renders draw from that wallet, and a FLUX 3 take costs more than the grant, so top up when the deliverable matters. Packs start at $10/800⚡. Image models stretch the grant furthest.
Yes. Speech, effects and ambience render in the same pass as the picture, and the audio arrives on the timeline ready for the editor. It is on by default. You can switch it off, and the render costs the same either way.
Any whole second from 5 to 20. It is a range, not a ladder, so 13 seconds is as dispatchable as 5. The composer opens on 5. On HD a 5-second take is ⚡174 (from $1.08) and a 20-second one is ⚡693 (from $4.30).
Yes, and the stills are frames rather than style references. One image is the opening frame. Two are the open and the close. Three to ten space out evenly across the take, or you place each one on the timeline yourself. Up to ten per render.
Two tiers: HD and FHD. The composer opens on HD. FHD costs more at every length, so draft on HD and buy the tier for the deliverable. A 20-second FHD take is ⚡1182 (from $7.34), against ⚡693 (from $4.30) on HD.
No. FLUX 3 is a video model on OpenClips, and the vendor's image family stays on FLUX.2, which OpenClips does not serve. Image work goes to the live image roster. Seedream 5.0 Pro covers typography and key art, Nano Banana Pro covers photo edits, GPT Image 2 covers precision work.
Seedance 2.5 for one unbroken take up to 30 seconds at ⚡41 (from $0.25). FLUX 3 for a mixed take under 20 seconds with sound already on it, at ⚡174 (from $1.08). Both share the composer, the wallet and the library.

What does FLUX 3 do on OpenClips?
Black Forest Labs announced FLUX 3 on 23 July 2026. One model, trained jointly across image and video, in early access at the vendor. OpenClips exposes the video half as flux-3-video. Text goes in, or up to ten stills, and a take comes back with its sound already on the timeline.
Why does the audio matter?
Speech, effects and ambience render in the same pass as the picture. There is no foley session and no dub. You can switch the audio off, and it costs the same either way.
Where do the stills go?
Attached images are frames, not style references. One still is the opening frame. Two are the open and the close. Three to ten space out across the take, or land where you place them.
What about FLUX for images?
The vendor's image family stays on FLUX.2, and OpenClips does not serve it. Typography-heavy key art goes to Seedream 5.0 Pro, photo edits to Nano Banana Pro, precision work to GPT Image 2.
