What is Seedance 2.5 Flash?

Seedance 2.5 Flash is the fast version of ByteDance's Seedance 2.5 video model, announced on November 12, 2026. It takes the same kinds of input, from a text prompt to images, frames, video and audio, and makes clips of up to 30 seconds with sound at 480p or 720p. ByteDance puts its quality close to the full model. Flash isn't in ChatCut yet: we're adding it after ByteDance opens its API on November 15. Until then, every clip on this page was made with Seedance 2.5 in ChatCut.

What Flashdoes better

ByteDance's own claims for Seedance 2.5 Flash. Until Flash is in ChatCut, each is shown with a Seedance 2.5 clip made for this page.

Close to the full model,in abouthalf the time

ByteDance built Flash to render about twice as fast as Seedance 2.5 while keeping its look close to the full model. This is the full model: spray, backlight and a whole herd in motion. A Flash take close to this is good enough to judge the shot.

Sound comes inthe same pass

Like Seedance 2.5, Flash generates the audio with the picture. The rain, the steel and the drum hit in this clip all came from the prompt, so you judge the picture and the sound together.

A third cheaper,so every lookgets a take

At about 34% less than Seedance 2.5 at 720p, four styles of the same shot will cost less than three full-model takes. Same fox, same jump; only the style line in the prompt changed.

Several shotsin one take

Flash takes the same prompts as Seedance 2.5, including several shots written in order. Here one clip cuts from first person through the canyon to a side tracking shot, then the aerial reveal, with the rider and the bike kept the same.

Every input Flash takes

Flash takes a text prompt, a first and last frame, or up to 10 images, 5 videos and 5 audio clips as references. These were made with Seedance 2.5, which takes the same kinds of input: here is what went in, and what came out.

One image, brought to life

Start from a still. The clip opens on your exact frame, then the coats, the dogs and the camera start to move.

  1. First frame: Image First frame Image
Seedance 2.5 · 16:9 · 6s
See the prompt

Fashion film. Start exactly on the first frame. The two women in long cobalt coats walk their two white greyhounds across the pink sand toward the right; the wind lifts their coats and the dogs' ears; the camera tracks alongside at their pace; their shadows stretch across the sand. Sound: wind, footsteps on sand, dog tags jingling. No subtitles.

Start and end on frames you choose

Give Flash the first and the last frame and describe what happens between them. Here a room is redecorated in one move.

  1. First frame: 0s First frame 0s
  2. Last frame: 8s Last frame 8s

Interior makeover in one shot. The camera stays still with a slow push in. Start exactly on the first frame and end exactly on the last frame. 0-3s: the sunny pink room is calm; the red armchair spins once and turns green. 3-6s: a black and white checkerboard rug unrolls across the wooden floor from the left, and a potted fig tree grows up beside the bookcase. 6-8s: the light settles as the room becomes the last frame. Sound: a soft whoosh, a fabric flutter, a gentle chime. No subtitles.

A person, a product and a song

Two reference images keep her face and the headphones consistent, and a music track sets the beat the cuts land on.

  2. @Image2: Product @Image2 Product
  3. @Audio1 Music · 8s

See the prompt

Social music clip. References: @Image1 is the woman (curly dark hair, round glasses, red knit sweater); @Image2 is the exact headphones (cream and tan, over-ear); @Audio1 is the music track and sets the beat. Look: 9:16, warm golden wall, late afternoon sun. 0-3s: she lifts the headphones from @Image2 and puts them on, smiling. 3-8s: she closes her eyes and dances to the beat of @Audio1, nodding and swaying, her curls bouncing; the cuts land on the beat. Keep her face and the headphones consistent. No subtitles.

Borrow a camera move from any clip

Pass a video as a reference and the model copies its camera path and speed onto a new scene. The hoverbike's flight became a paper plane's.

  1. @Video1: Camera move @Video1 Camera move
Seedance 2.5 · 16:9 · 10s
See the prompt

References: @Video1 supplies the camera movement only: a fast, low first-person flight weaving through a narrow canyon of buildings. New scene: a paper airplane folded from an old train ticket flies through a narrow cobblestone street in an old European town at sunrise, following the same path and speed as @Video1, skimming past flower boxes, laundry lines and a cafe awning, then soaring up over the rooftops. Look: 16:9, warm sunrise light, motion blur. Sound: wind rush, paper flutter, church bells. No subtitles.

Seedance 2.5 Flash FAQ

What is Seedance 2.5 Flash?

A faster, cheaper version of Seedance 2.5 that ByteDance announced on November 12, 2026. ByteDance says it renders about twice as fast and costs about 34% less at 720p, with quality close to the full model.

Is Seedance 2.5 Flash available in ChatCut?

Not yet. Flash is coming to ChatCut soon, after ByteDance opens its API on November 15, 2026. Until then, use a short Seedance 2.5 clip at 480p for quick, cheap takes.

What can I use until Flash arrives?

Seedance 2.5 at 480p. In Video Gen, pick Seedance 2.5 and set 480p: the clip is a draft, priced like any 480p clip, and you can turn the one you like into a 1080p or 4K final of the same shot.

What resolution and length does Flash support?

480p or 720p, up to 30 seconds per clip. For 1080p or 4K, use Seedance 2.5.

Can Seedance 2.5 Flash turn an image into a video?

Yes. Give it one image as the first frame, or a first and a last frame, and describe the motion. You can also pass up to 10 images as references for characters, products or places.

Does Seedance 2.5 Flash make sound?

Yes. Flash generates dialogue, effects and music with the picture. You can also pass audio clips as references for a voice or a beat.

Is Flash the same as a Seedance 2.5 draft?

No. A draft is a 480p clip from the full model that you can turn into a 1080p or 4K final of the same shot. Flash is a separate model: for a higher-resolution version you generate the shot again on Seedance 2.5 or in 4K, so the new take will differ.

How many references can Flash use?

Up to 10 images, 5 videos and 5 audio clips in one request. Seedance 2.5 takes up to 50 in all: 30 images, 10 videos and 10 audio clips.

How much will Seedance 2.5 Flash cost?

ByteDance prices Flash about 34% below Seedance 2.5 at 720p. ChatCut will set its credit price when Flash arrives; as with every model, the editor shows the exact estimate before you send.

Do I need a paid plan?

Yes. Video generation in ChatCut needs a paid plan, and each clip uses credits. The editor shows the estimate before you send.

When should I use Seedance 2.5 instead?

When you need 1080p, more than 20 references, or the take you are going to deliver. Flash is for finding the shot; Seedance 2.5, at 1080p or 4K, is for finishing it.
