Seedance 2.0 Fast Reference to Video

Seedance 2.0 Fast Reference to Video is ByteDance's most advanced reference-driven video model, delivered in a fast tier tuned for quicker results without sacrificing creative range. Instead of generating a video from a text prompt alone, it lets you feed the model your own reference material and then choreograph how those elements come together on screen. You can combine up to nine reference images, up to three reference videos, and up to three audio clips in a single generation, mixing and matching visual and sonic sources to steer the look, motion, and sound of the finished clip.

What sets this model apart is how directly you can point to your references inside your prompt. Every image, video, and audio file you upload gets a simple handle, so you write things like @Image1, @Video2, or @Audio1 right in your description to tell the model exactly which source should influence which moment or subject. That means you are not just hoping the model picks up on a mood, you are naming the character from one image, the motion style from a clip, and the voice or ambience from an audio track, then describing how they interact. It is a workflow built for transforming and stylizing existing material, carrying characters and looks across shots, and lip-syncing performances to supplied audio.

The model outputs finished video with synchronized audio. When audio generation is turned on, it produces sound effects, ambient noise, and lip-synced speech that match the action on screen, so a talking subject moves its mouth in time with the words. If you would rather supply your own soundtrack or voice, you can provide reference audio clips and refer to them in your prompt. Note that whenever you include reference audio, you also need at least one reference image or video so the model has something visual to anchor the sound to.

You have flexible control over framing. Choose from a full set of aspect ratios including widescreen 16:9 for landscape, 9:16 for vertical and mobile-first content, 1:1 square for social feeds, ultrawide 21:9 for cinematic sequences, plus 4:3 and 3:4 options, or let the model decide automatically based on your prompt. Duration is equally adaptable: generate clips anywhere from 4 to 15 seconds, or set it to automatic so the length fits the story you have described. This range makes it easy to produce everything from a quick looping social clip to a longer narrative beat.

For output quality, you can pick between 480p for faster generation and 720p for a balanced result. There is also a quality control that lets you request a higher-quality, larger-file version when you want the cleanest possible footage, or stick with the standard version for smaller files. These settings let you trade speed and file size against fidelity depending on whether you are quickly iterating on ideas or exporting a final piece.

The supported inputs are broad and practical. Reference images can be JPEG, PNG, or WebP. Reference videos can be MP4 or MOV, and each one should sit roughly between 480p and 720p in resolution, with the combined length of your clips falling between 2 and 15 seconds. Reference audio can be MP3 or WAV, with the total audio running no longer than 15 seconds across all clips. Across every type of file combined, you can include up to twelve reference items in a single generation, giving you a rich palette to draw from while keeping things manageable for the model.

This model is a strong fit for a wide set of creative professionals. Filmmakers and video editors can use it to stylize and transform footage, extend a scene, or blend multiple takes into a single cohesive shot. Content creators and social media producers benefit from the vertical and square framing options and short, punchy durations built for feeds. Character designers and animators can lean on the reference system to keep a subject recognizable across a clip and to drive lip-sync from a supplied voice. Musicians and audio storytellers can pair a track with visuals and let the model align motion to sound. Because you can reference specific sources by name in the prompt, the model rewards deliberate, descriptive direction: the more clearly you spell out which reference does what and how the scene should unfold, the more control you get over the result.

A few practical considerations are worth keeping in mind. Reference audio always needs at least one reference image or video alongside it. Your reference videos need to fall inside the supported resolution and length windows, and your total combined audio must stay within fifteen seconds. The overall reference count across images, videos, and audio tops out at twelve files, so plan which sources matter most to your shot. Higher resolution and higher quality produce better-looking, larger files but take more time to render, while 480p and the standard version are ideal for fast iteration. As with any reference-based generation, results improve when your source material is clean, well-lit, and clearly framed, and when your prompt names each reference explicitly and describes the motion, mood, and sound you want. Used this way, Seedance 2.0 Fast Reference to Video becomes a flexible tool for turning your own images, clips, and audio into short, sound-synced videos with a look you direct.
