What is Seedance 2.5, and how do you use it?

Seedance 2.5 is the AI video model Agent Social films with by default. You never set it up or open a separate account: you describe a story in the studio chat, and every shot comes back as a clip with the voices and the sound of the scene already in it.

What is Seedance 2.5?

Seedance 2.5 is the AI video model that Agent Social uses to film every clip of your story. The studio writes each shot, hands it to the model, and gets back a video of 4 to 30 seconds with the characters speaking and the scene’s sound in place. One clip can cut between several shots, like a scene in a film. It is already selected when you open a film, so a new film needs no setup. All five episodes of OVERCLOCK, the photoreal kaiju series made in Agent Social, were filmed on it. If you were searching for Seedance 2.0, note that Seedance 2.5 is the only Seedance in the Agent Social menu, so you never have to choose between versions or work out which one a guide was written for.

What is Seedance 2.5 good at?

Seedance 2.5 is best at three things that a story needs. First, faces: the same person stays recognisable from one shot to the next, which is why a series can run on it. Second, sound made with the picture: a character who is written to shout comes back shouting, and the rain, the rotors or the radio in the scene arrive in the same clip, so you never record or match audio yourself. Third, length: clips run from 4 to 30 seconds, long enough for a whole beat of a scene. In OVERCLOCK Episode 5, the creature’s jaws coming out of the smoke are a single 30-second take, used whole on the first try. The model also accepts lifelike faces, including a photo of yourself, so you can play a character in your own film.

How do I use Seedance 2.5 in Agent Social?

You use Seedance 2.5 by describing your film in the studio chat and letting the studio do the filming. You never write a technical prompt. Type one line or paste a whole script, read the chapters and the screenplay of each clip, change anything in plain words, and only then film. The studio makes your cast and places once as pictures you check, so the model sees the same faces in every shot. Clips are filmed one after another in story order, and you watch each before the next. If one comes out wrong, you ask for that clip again. The Seedance 2.5 page shows the same path in short, and the guide to picking a video model goes deeper on the menu.

From one line to a filmed clip on Seedance 2.5
  1. Describe the film

    Write one line or paste a story. Seedance 2.5 is already selected.

  2. Read what the studio wrote

    Check each chapter and each clip’s screenplay, and ask for changes in plain words.

  3. Check the cast and places

    Fix any picture that looks wrong now, before it is used in a clip.

  4. Film chapter 1, clip 1

    Watch it with its voices and sound, then film the next clip.

How do I pick Seedance 2.5 in the model menu?

Open the Video tools menu in your film’s chat and pick Seedance 2.5 and a resolution together. Nothing changes until you close the menu, and the chat then shows one line saying what happened to your clips. You can also ask in the chat, for example “Move this film to Seedance 2.5”, and the studio makes the same switch. With no film open, the same menu sets the default for new films. To change only one clip, open it and use its Generation model setting. A new episode of a series starts on the model the previous episode used. Switching never deletes a clip you already made, and a clip only uses credits when you film it again.

How long can a Seedance 2.5 video be?

One Seedance 2.5 clip runs from 4 to 30 seconds, and a film can be as long as your story needs, because the studio joins as many clips as the story takes. A chapter is one scene, made of one or more clips. The finished length comes from the number of chapters, not from a limit on any one clip. The three latest OVERCLOCK episodes show how the shape bends to the story, from a little under five minutes to a little over ten. Each was written, filmed in order and joined in Agent Social, and every clip was filmed on Seedance 2.5.

Is Seedance 2.5 the right model for every clip?

Seedance 2.5 is the right choice for almost every film, and the other model in the Agent Social menu, MiniMax H3 Max, is for a short clip that stands on its own. The menu marks MiniMax H3 Max “Fastest”, and it films shorter clips. In my own test with my photo as the character, my face and outfit changed between shots on MiniMax H3 Max and held on Seedance 2.5, so anything with recurring characters or long takes should stay on the default. If a clip would still make sense posted alone, such as an ad or a teaser, you can try the other model on just that clip and compare.

Answer each question for your verdict.

What does Seedance 2.5 cost in Agent Social?

Agent Social is pay as you go and prices a film per finished minute: from $25, up to 1080p. There is no subscription, no free trial and no free credits, and unused credits never expire. Draft the film to judge every clip, because a draft is enough to check the story, the faces, the timing and the sound, then upscale the finished film to 1080p once at the end, as described in draft first, then upscale to 1080p. Retakes add to the total, so read each screenplay before you film it, and judge every clip in the draft before you decide what the finished film needs. The pricing page lists every charge.
