Fast Cinematic Text-to-Video with Seedance 2 Fast
ByteDance's Seedance 2 Fast is the quick, lower-cost tier of Seedance 2 — cinematic text-to-video with synchronized audio at a cheaper per-second rate. Pick any duration from 4 to 15 seconds at 480p or 720p, with audio included in the price, and iterate faster than on the full model.
What makes Seedance 2 Fast different
The iteration tier of Seedance 2
Seedance 2 Fast is the same cinematic Seedance 2.0 family tuned for speed and cost: roughly 20% cheaper per second than the full model at both 480p and 720p, with quicker turnaround. It's built for the exploratory phase — trying prompts, blocking shots, testing motion — where you generate ten clips to keep one.
Synchronized audio at no extra cost
Like its bigger sibling, Fast generates voice, sound effects, and background music together with the picture in a single pass — and the per-second price is identical with audio on or off. Leave the toggle on for sound-on drafts, or flip it off for silent footage; either way you pay the same rate.
4 to 15 seconds, priced per second
Choose any whole-second duration from 4 to 15 and pay only for what you generate: a 5-second 480p draft is about $0.45, a 10-second one about $0.90. Aspect ratios run from 21:9 cinematic wide to 9:16 vertical, or stay on Auto and let the prompt decide the frame.
Draft on Fast, finish on Seedance 2
Fast caps at 720p, while the full Seedance 2 adds a 1080p super-resolution tier. On a Scenetra board the two sit side by side: iterate your prompt on a Seedance 2 Fast node until the shot works, then paste the winning prompt into a Seedance 2 node for the full-quality 1080p final — same settings, same canvas.

What is Seedance 2 Fast?+
Seedance 2 Fast is the quick, lower-cost tier of ByteDance's Seedance 2.0 video model. It generates cinematic clips from text prompts — 4 to 15 seconds at 480p or 720p — with synchronized audio included, at a cheaper per-second rate and faster turnaround than the full Seedance 2. On Scenetra it comes in three modes: Text to Video, Image to Video, and Reference to Video.
How much does Seedance 2 Fast cost?+
On Scenetra, about $0.09 per second at 480p and $0.20 per second at 720p, audio included. A 5-second 480p clip is about $0.45; 10 seconds at 720p is about $1.94. Billing is pay-per-generation from your credit balance — every model is billed at provider cost with 0% markup, and there's no subscription gating the model.
What's the difference between Seedance 2 Fast and Seedance 2?+
Fast is the iteration tier: roughly 20% cheaper per second (about $0.09/s vs $0.11/s at 480p, $0.20/s vs $0.24/s at 720p) and quicker to generate, but it tops out at 720p, while the full Seedance 2 adds a 1080p super-resolution tier. Both are on Scenetra, so a common pattern is drafting on Fast and re-running the winning prompt on Seedance 2 for the 1080p final.
Does Seedance 2 Fast generate audio?+
Yes — audio is on by default. The model generates synchronized voice, sound effects, and background music together with the picture, and the per-second price is the same whether audio is on or off. Toggle it off if you need silent footage.
Can I try Seedance 2 Fast for free?+
Yes — new Scenetra accounts start with free welcome credits and a 7-day trial, which cover your first generations. At about $0.45 per 5-second 480p clip, the welcome credits go a long way on Fast. After that it's pure pay-per-generation with nothing recurring to cancel.
What durations and aspect ratios does Seedance 2 Fast support?+
Any whole-second duration from 4 to 15 seconds, billed per second. Aspect ratios span 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, plus an Auto mode that picks a frame based on your prompt.
When should I use Fast instead of Seedance 2 Mini?+
Both are cheaper Seedance tiers on Scenetra. Fast is a lower-cost, quicker cut of the full Seedance 2.0 generation, while Mini is its own compact model tuned for the lowest cost per second. If you want output closest to full Seedance 2 for drafting, use Fast; if minimum spend per clip matters most, compare it against Mini on the same board — running one prompt through both takes seconds.
