    AI video fast enough to iterate in one sitting

    Seedance 2.0 Fast is the speed-tuned tier of the 2.0 line. Short clips typically come back in roughly 30 to 60 seconds, so prompt tuning feels like a live conversation. Longer single takes belong on Seedance 2.5, and they take proportionally longer to render.

    • Tight turnaround keeps the idea-to-render loop under a minute for most clips
    • Same-session iteration means prompt tweaks while the reference stays in mind
    • Fast drafts at 480p, then promote winners to 720p without switching models

    Why Seedance 2.0 Fast feels fast

    Fast is tuned for short turnaround so creative teams can stay in flow. Exact times depend on queue load, duration and resolution: longer clips and 720p jobs take more wall time than 4-second 480p drafts. Length is the thing that costs you wall time, which is also why a 30-second Seedance 2.5 take is not a drafting tool.

    • 480p at 19 credits/sec for quick drafting passes
    • 720p at 31 credits/sec when the shot needs to be sharper
    • Durations 4 to 15 seconds in integer steps
    • First plus last frame keyframing for deterministic motion paths
    • Seedance 2.0 Mini is cheaper still at 12 cr/s if the draft does not need Fast

    How it works

    1. Prompt and hit generate

      Write a direct beat, subject and motion and lighting, then submit. Seedance 2.0 Fast starts working immediately.

    2. Iterate in the same tab

      Short render times let you tune the prompt, swap a reference image, or retry a seed without losing momentum.

    3. Promote the take that lands

      Save the best version as a reference and generate its neighbours, or step up to 720p for final delivery.

    Teams that benefit from speed

    • Social creators prototyping hooks against a live trend
    • Ad teams running rapid A/Bs before a Monday launch
    • Storyboard artists interpolating keyframes in tight review windows

    Speed isn't magic

    Fast means the Fast tier and short clips. 15-second 720p jobs still take longer than 4-second 480p drafts, and queue load varies. A 30-second Seedance 2.5 render is a different job entirely and should be planned as one. The point is that the drafting loop stays tight enough to keep iterating.

    FAQ

    • Short 480p clips typically come back in roughly 30 to 60 seconds. Exact wall time depends on duration, resolution and the current queue, and 720p and longer clips take more.

    • Yes. Fast is the speed-tuned tier at 19 credits/sec at 480p and 31 at 720p. Standard Seedance 2.0 costs more per second and is the only tier that renders 1080p and 4K. Mini sits below Fast at 12 cr/s. All three are 2.0; Seedance 2.5 is the newer release and is a separate card.

    • You choose the resolution. 480p is the speed and value option; 720p is sharper and costs more per second. Both are the same Seedance 2.0 Fast model. For a 1080p or 4K master, use standard Seedance 2.0 instead.
