Seedance V1 is the first-generation ByteDance video model that put the family on the map, and it remains a smart pick when cost efficiency matters more than cutting-edge specs. Rather than one do-everything endpoint, V1 splits into purpose-built variants — Pro and Lite quality tiers, each with dedicated text-to-video and image-to-video versions, plus a Pro Fast option that speeds up image animation.
Five variants are live on Flux 3 AI: V1 Pro T2V, V1 Pro I2V, V1 Pro Fast I2V, V1 Lite T2V, and V1 Lite I2V. Pro tiers chase fidelity; Lite tiers minimize spend. All of them include the fixed-lens camera lock, the image-to-video variants accept a reference image for subject fidelity, and every variant selects among 480p, 720p, and 1080p output.
Clips run 5 or 10 seconds. Text-to-video variants frame up to 21:9 ultrawide, while image-to-video variants add a 9:21 tall format suited to full-screen phone stories. A sensible ladder: prove the concept on V1 Lite, then move winning prompts up to V1 Pro — or on to Seedance 1.5 Pro or 2.0 when a project earns a bigger budget.

Which Seedance V1 version should you use?
Every version below is selectable in the Create studio on the same credits.
Seedance V1 Pro (T2V)
The prompt-only Pro endpoint. It generates 5- or 10-second clips at 480p, 720p, or 1080p across six ratios including 21:9 ultrawide, with the fixed-lens camera lock and style presets. Pick it when you have no source image and want the highest V1 fidelity from text alone.
Seedance V1 Pro (I2V)
Pro-quality animation for an uploaded still. Same 5- or 10-second durations and three resolutions, but the ratio menu swaps 21:9 for an extra-tall 9:21 story format, and one reference image can reinforce the subject. Choose it when a photo or render needs to move with maximum polish.
Seedance V1 Pro Fast (I2V)
An accelerated twin of the Pro image endpoint — identical durations, resolutions, 9:21 support, single reference image, and fixed-lens control, tuned to return results sooner. Reach for it when you are animating a stack of stills against a deadline and turnaround matters more than squeezing out the last detail.
Seedance V1 Lite (T2V)
The cheapest way to generate V1 video from words. Specs mirror the Pro text variant — 5 or 10 seconds, up to 1080p, six ratios with 21:9, fixed lens — at a lower credit price with lighter fidelity. Use it to validate prompts in volume before promoting winners to a Pro tier.
Seedance V1 Lite (I2V)
Budget image animation. It accepts an uploaded still plus one reference image, renders 5- or 10-second clips at 480p to 1080p, and includes the 9:21 tall format and camera lock. The right pick for bulk photo animation, tests, and social content where cost per clip is the deciding spec.
Seedance V1 prompt examples
Copy one as a starting point, or send it straight to the Create studio.
“A cartoon fox chef flipping pancakes in a cozy kitchen, bouncy exaggerated motion, bright flat colors, static wide shot, playful Saturday-morning cartoon energy.”
Stylized scene that stays charming even on the budget Lite tier.
“Time-lapse clouds racing over a desert mesa while shadows sweep across red rock, locked-off wide angle, deep blue sky, vast and serene.”
Fixed-lens landscape testing smooth time-lapse motion.
“Animate the uploaded sneaker photo: it rotates on a glowing pedestal, camera orbiting slowly opposite the spin, dust motes catching studio light, sleek commercial feel.”
Image-to-video product spin suited to the I2V variants.

Seedance V1 questions, answered
What is Seedance V1?
Seedance V1 is ByteDance’s first-generation video model, offered on Flux 3 AI as five variants: Pro and Lite tiers, each with text-to-video and image-to-video versions, plus a faster Pro image-to-video option. It produces 5- or 10-second clips at up to 1080p.
What separates Seedance V1 Pro from V1 Lite?
Pro renders with higher fidelity and detail; Lite costs fewer credits and suits volume work where perfect polish is optional. Both tiers share identical durations, resolutions, and the fixed-lens control, so prompts move between them freely.
Does Seedance V1 do image-to-video?
Yes — three of the five variants are image-to-video: V1 Pro, V1 Pro Fast, and V1 Lite. Each animates an uploaded still and accepts a reference image to help preserve the subject through the motion.
What durations and resolutions does Seedance V1 support?
Every variant generates 5- or 10-second clips and outputs at 480p, 720p, or 1080p. Aspect ratios include 21:9 ultrawide on the text variants and a 9:21 vertical format on the image variants.
Is Seedance V1 still worth using over newer Seedance models?
For many jobs, yes. V1 Lite is the cheapest route into the Seedance look, and V1 Pro remains solid for everyday content. Step up to Seedance 1.5 Pro for 12-second clips or Seedance 2.0 for 4K and heavy reference work.
What is the Pro Fast variant for?
V1 Pro Fast is an accelerated image-to-video endpoint: it keeps the Pro tier’s output quality while returning results sooner, which makes it the right pick when you are animating a batch of stills against a deadline.
Can I use Seedance V1 clips in commercial projects?
Yes. Content generated through Flux 3 AI may be used commercially under the platform’s terms, and every download arrives without a watermark — the same policy that applies across all models on the site.
Seedance V1 vs Hailuo 02 — when should I pick which?
Reach for Seedance V1 when you want the fixed-lens camera lock, 480p budget drafts, or 21:9 and 9:21 framing. Hailuo 02 is the stronger choice for lifelike physics and weighty motion. Both bill from the same Flux 3 AI credit pool, so testing one prompt on each is cheap.
How much does a Seedance V1 video cost to generate?
Each variant has its own credit price, shown in the studio before you generate — Lite tiers sit at the bottom of the range, Pro tiers cost more. Credits come from free sign-up bonuses or the plans and packs available on the pricing page.
