Seedance 2.0 Fast Reference to Video From Images and Clips

Last verified: November 3, 2026

Seedance 2.0 Fast works best on short clips that need to follow material you already have. That could be a product photo, a character design, a storyboard sheet or a phone clip with a movement you want to reuse. It supports the same image references, video references and image-plus-video references as the full Seedance 2.0 model, so the faster tier keeps the whole reference workflow. That makes Seedance 2.0 Fast reference-to-video a practical way to put existing assets in motion: your files decide how things look, and your prompt decides what happens.

A reference shows more than its subject. Seedance 2.0 can take composition, motion, camera movement and visual effects from the files you give it. One well-chosen image can therefore replace a paragraph of description that would still leave proportions, layout or lighting to chance. The clearer each file is about the one thing you want from it, the less your prompt has to work against it.

On Vidofy everything happens in one form. Images go into Add Image, optional motion clips go into Add Video, and your instructions go into Prompt. Enhance Prompt can expand a rough idea for you. Video Duration, Resolution and Aspect Ratio shape the render, and Generate Audio and Web Search are switches you set before generating. Start with images only, check how closely the result follows them, and add a clip only when the motion itself has to match something.

Prompting Techniques for Reference Uploads

Naming Each Upload and the One Thing to Take From It

Seedance's own reference prompts refer to an upload by type and number, such as @Image 1. The model then takes composition, camera language, motion rhythm or other elements from that file as the prompt tells it to. Write one clause per file, for example '@Image 1 for the jacket and its stitching, @Image 2 for the warehouse lighting, @Image 3 for the color grade'. Then say what to ignore, so a reference's background or props stay out of the shot. Add the images in the order you plan to number them so the labels are easy to keep track of.

Writing Out Expressions, Movement and On-Screen Text

ByteDance reports that Seedance 2.0 follows instructions better on character behavior, facial expression, movement through space and on-screen text. Those details are worth writing out rather than leaving to the reference. Describe how an expression changes ('her frown softens into a grin') and where the subject moves in the frame ('crosses from left to right and stops at the window'). Put any sign, label or title card in quotation marks with the exact spelling. If Enhance Prompt expanded a rough line for you, check that the suggestion still names your uploads before you keep it.

Steps to Generate a Video From Your References

Six steps, from uploading references to downloading the finished clip.

1

Upload reference images in "Add Image"

Add at least one image, because the form needs one to run. Give each file a single job: the subject, the setting, a storyboard panel or a look you want matched. Crop away clutter around the subject and skip heavy filters, because anything in the frame is material the model may borrow.

2

Add optional motion clips in "Add Video"

Leave "Add Video" empty for an image-only run, which is the simplest place to start. Add a clip when a camera move, a routine or a rhythm has to match existing footage. Trim it to just that movement first, because the form limits the total length of all clips and every extra second is more footage for the model to interpret.

3

Write your instructions in "Prompt"

Describe the action, the shot and what each upload contributes, within the box's 2,048-character limit. If you only have a rough line, click "Enhance Prompt" under the box to get fuller suggestions. Your text only changes when you pick one, so you can compare versions without losing your original.

4

Set "Video Duration", "Resolution" and "Aspect Ratio"

"Video Duration" runs from 4 to 15 seconds in one-second steps and starts at 4. "Resolution" offers 480P or 720P and starts at 480P. "Aspect Ratio" offers 1:1, 3:4, 4:3, 9:16 and 16:9 and starts at 1:1. Draft at 480P with a short duration to check that your references are followed, then switch to 720P for the version you keep. Pick the ratio that fits where the clip will be posted, since the square default rarely suits widescreen or vertical feeds. Check the two switches too: "Generate Audio" starts on, and "Web Search", which uses online search, starts off.

5

Start the run with "Generate"

Each run returns one video. To try variations, change one thing between runs (a reference, a clause in the prompt or the duration) so you can tell which change made the difference.

6

Download the finished video

Watch the whole clip before downloading and check what you assigned to each upload: the subject's details, the setting and the movement. If one of them drifted, rewrite the clause that names that file and run it again instead of adding new instructions on top.

Choosing Between Reference Uploads and a Text-Only Prompt

When your files should drive the clip, and when a written prompt is the better starting point.

What you start from You start from your own reference images, with optional reference clips, plus a prompt that says how to use them. The Text To Video mode of the same model builds the whole scene from your written prompt. Pick reference-to-video when the files already exist and have to shape the result, and pick Text To Video when the idea still exists only in words.
Matching an existing look The model can borrow composition, motion, camera movement and visual effects from your uploads, following what the prompt tells it to take. Text To Video gets the look from how the prompt describes the subject, setting, light and style. Choose reference-to-video for a specific product, character design or location that must look like the same thing, and choose Text To Video when a close approximation is enough.
Getting a specific camera move A reference clip can pass its camera movement, choreography and pacing on to the new shot. Text To Video takes its camera move from the shot language in the prompt, such as a slow dolly-in or an orbit. Use a reference clip when a move is hard to put into words or has to match existing footage, and write it out in Text To Video when a standard named move does the job.
Stay with reference-to-video whenever an uploaded file has to decide how the clip looks or moves, and switch to Text To Video for ideas that exist only as words.

Fixes for Common Reference-to-Video Problems

What usually goes wrong with references and clips, and what to change before the next run.

My reference image of a real person gets rejected

Seedance 2.x models don't accept reference images or videos that directly show real human faces. A photo of yourself, an actor or a customer is refused because of what it contains, so sending the same file again won't help. Replace it with a reference that has no real face, such as an illustrated, 3D-rendered or stylized character, or a costume, product or location shot, and run it again. The same applies to clips in Add Video.

My image won't upload to Add Image

Usually the file is in a format the box doesn't accept, larger than the per-file size limit, or smaller than the minimum dimensions. Re-export it in one of the accepted image formats and compress or resize it so it fits under the size limit without dropping below the minimum dimensions. Then add it again. You don't need to start a run until the upload works.

My reference clip won't attach in Add Video

Check three things: the file type, the per-clip size limit and the total length of all your clips, since the length limit covers every clip together rather than each one. Trim each clip to the few seconds that show the movement you need, convert other formats to one the box accepts, and lower the bitrate if the file is still too large. Then attach it again.

My prompt is too long to fit in the box

The Prompt box has a character limit, and long prompts often use it up describing what the images already show. Cut descriptions of appearance that a reference already covers, keep the action, the camera and one clause per upload, and add another reference image for details you can't fit in words. Then generate again.

The video came back with sound I didn't want

Generate Audio decides whether the clip comes with sound, and it was on for this run. Switch Generate Audio off and run again if you plan to add music or voice in your editor. Leave it on when you want the clip to arrive with sound.

Frequently Asked Questions

Which files can I upload to Seedance 2.0 Fast, and what are the limits?

Add Image takes 1 to 9 images in JPG, JPEG, PNG or WEBP format. Each can be up to 10 MB and must be at least 300×300 pixels, and at least one image is required. Add Video is optional and takes up to 3 clips in MP4 or MOV, each up to 10 MB, with no more than 15 seconds of footage across all of them. You also need to fill in the Prompt box.

Do I need to upload a reference video, or are images enough?

Images are enough, because the video upload is optional. An image-only run is the simplest way to see how the model reads your references. Add a clip when a specific movement or pacing has to match existing footage, and say in the prompt what that clip should contribute so its subject or setting doesn't take over the shot.

What makes one generation cost more than another?

The credit cost of each run is calculated from the options you choose and appears above the Generate button once you're signed in. It changes with Video Duration, Resolution, whether you upload a video, and how long the uploaded videos are.

What resolution and frame rate does Seedance 2.0 Fast produce, and can it do 1080p?

Seedance 2.0 Fast renders MP4 video at 480p or 720p at 24 frames per second. 1080p isn't supported on the Fast model. For the sharpest result, choose 720P in Resolution for the run you plan to keep.
