Seedance 2.0 Fast Reference to Video

Seedance 2.0 Fast Reference to Video is ByteDance's most advanced reference-to-video model, delivered in a fast tier that emphasizes lower latency without sacrificing creative power. At its core, this model turns your written ideas into fully realized videos — but its standout feature is how richly it can be guided. You can feed it reference images, reference videos, and even reference audio, then describe in plain language how you want them woven together into a finished clip. This makes it a remarkably flexible tool for artists, designers, filmmakers, and content creators who want precise control over the look, motion, and sound of their generated videos.

The model accepts an unusually broad range of inputs. Alongside your text prompt, you can include up to 9 reference images (in JPEG, PNG, or WebP format, each up to 30 MB), up to 3 reference videos (MP4 or MOV, with a combined duration between 2 and 15 seconds and each clip between roughly 480p and 720p resolution), and up to 3 reference audio clips (MP3 or WAV, with a combined duration of no more than 15 seconds and each file up to 15 MB). Across all of these, you can supply a total of up to 12 files. The beauty of this system is in how you reference them: in your prompt, you simply call out @Image1, @Video2, @Audio3, and so on, telling the model exactly how each piece should contribute to the scene. This gives you a level of compositional direction that feels closer to directing a shoot than typing a single instruction.

When it comes to output, the model produces polished video files with optional synchronized audio. The audio generation is a true highlight: it can create sound effects, ambient sound, and even lip-synced speech that matches the action on screen, all generated in step with the visuals. You're free to turn audio generation on or off depending on your project, and you have full control over how long your video runs — anywhere from 4 to 15 seconds, or you can let the model automatically decide the ideal length based on your prompt. This flexibility makes it equally suited to short social clips and longer narrative beats.

Framing and format are entirely in your hands as well. You can choose landscape (16:9), vertical (9:16) for mobile-first platforms, square (1:1), classic (4:3), portrait (3:4), or sweeping ultrawide cinematic (21:9), or hand the decision to the model with an automatic setting. Resolution can be set to 720p for a balanced result or 480p when you want faster generation. For projects that demand the cleanest possible result, you can also request a higher-quality output that produces a larger, more detailed file, while a standard setting keeps things efficient.

The model is tagged for stylized work, transformation, and lip-sync — three areas where it genuinely shines. Because it can blend reference imagery and footage with your text direction, it's ideal for transforming existing material into new styles, building stylized scenes from scratch, or driving believable lip-synced performances when you provide audio. Note that audio references come with one rule: if you supply audio, you must also include at least one reference image or video, giving the model a visual anchor for the sound.

Who benefits most? Filmmakers and motion designers can previsualize scenes, generate stylized inserts, or create animated sequences guided by mood boards and reference clips. Social content creators can produce vertical, audio-rich videos with synchronized speech and effects. Designers and digital artists can transform their illustrations or photographs into moving, sounding pieces. Anyone working on character-driven content can take advantage of the lip-sync capabilities to bring spoken lines to life. The reference-driven workflow also makes the model a strong fit for maintaining consistency — by feeding in the same characters, objects, or environments as references, you can keep a coherent look across multiple generations.

In terms of creative workflow, the model rewards thoughtful prompting. Because you can reference specific images, videos, and audio by name within your description, you can choreograph complex scenes — describing cut scenes, action sequences, and transitions, much like the example of an octopus discovering a football and rallying its friends for an underwater game. This narrative-style prompting, combined with multi-reference input, lets you build sequences that feel directed rather than randomly generated.

A few practical considerations to keep in mind: reference videos must fall within the supported duration and resolution ranges, and the combined size and count limits across all your inputs need to be respected for the model to work properly. Choosing 480p will speed up generation when you're iterating, while 720p delivers a more balanced final result. The high-quality option is best reserved for finished pieces where file size is less of a concern. Whether audio is generated or not does not change how the model treats your project, so you can experiment freely with sound on or off.

Overall, Seedance 2.0 Fast Reference to Video stands out for its combination of speed, multi-reference control, and built-in synchronized audio. It's a versatile creative engine that lets you direct video generation with images, footage, sound, and words all working together — making it a powerful addition to the toolkit of any creator who wants more than a single-line prompt can offer.
