Seedance 2 Image to Video

Seedance 2 Image to Video is ByteDance's most advanced image-to-video model, built to turn a single still image into a fully animated, cinematic video complete with synchronized audio. Instead of just adding subtle movement to a photo, this model brings scenes to life with directed motion, camera dynamics, and even sound effects, ambient audio, and lip-synced speech — all generated together so the finished clip feels like a real piece of footage rather than a moving snapshot.

At its core, the workflow is simple: you provide a starting image and a text prompt describing the motion and action you want, and the model animates that image into a coherent video sequence. The prompt is where you direct the scene — you can describe not just how things should move but also narrative beats, like a subject discovering an object and reacting to it, or a cut to a completely new moment within the same clip. This makes it well suited to storytelling, where you want a shot to evolve rather than simply loop.

One of the standout features is native synchronized audio. When audio generation is turned on, the model produces sound that matches the on-screen action: ambient environmental sounds, sound effects tied to what's happening, and lip-synced speech for characters. Because the audio is generated alongside the visuals, the timing lines up naturally, which removes the need to source and manually sync sound in a separate editing pass. If you prefer a silent clip to score yourself, you can simply turn audio off.

Seedance 2 also gives you precise control over the beginning and end of your shot. Beyond the required starting frame, you can optionally supply an ending image, and the model will generate a smooth transition that travels from your first image to your last. This start-and-end frame control is especially useful for morph effects, before-and-after reveals, transformations, and any sequence where you need the clip to land on a specific final composition. Combined with motion prompts, it lets you choreograph exactly where a shot begins and ends while letting the model fill in the movement between.

The model supports a wide range of output resolutions to match your project and delivery needs. You can choose 480p for faster generation when you're iterating or roughing out ideas, 720p for a balanced result, 1080p for high-quality final output, and 4k for the highest fidelity. Duration is flexible too: you can generate clips anywhere from 4 to 15 seconds, or let the model automatically decide the best length based on your prompt. That range makes it practical for short social clips, product moments, animated vignettes, and longer narrative beats alike.

Aspect ratio control rounds out the framing options. You can render in 16:9 for landscape, 9:16 for portrait and vertical formats made for phones and social feeds, 1:1 for square, 21:9 for ultrawide cinematic looks, or 4:3 and 3:4 for other framing needs. There's also an automatic mode that infers the aspect ratio directly from your input image, so your animation keeps the composition you started with. For creators who need cleaner, higher-fidelity results, there's an option to request a higher-quality output when you want the sharpest possible final file.

The model works with common image formats including JPEG, PNG, and WebP, and accepts source images up to 30 MB, so you can bring in high-resolution artwork, photographs, renders, or design compositions as your starting point. Its strengths lie in stylized and illustrative imagery, dramatic transformations between frames, and character speech with synced mouth movements.

Who benefits most? Filmmakers and motion designers can use it to previsualize shots or produce finished cinematic sequences from concept frames. Social content creators can quickly turn a single image into a vertical, sound-complete clip ready for feeds. Illustrators and digital artists can see their static pieces move and speak, opening the door to animated storytelling without a full animation pipeline. Marketers and product teams can animate hero images and craft transformation reveals using the start-and-end frame feature. Because the audio, motion, and framing all come from one generation pass, small teams and solo creators can achieve results that would normally require several separate tools and steps.

A few things to keep in mind. Every generation is driven by your prompt and starting image, so clear, descriptive prompts that specify both the action and the mood tend to produce the strongest results — describing camera moves, reactions, and scene changes gives the model more to work with. If you want a guaranteed final composition, providing an end image is the most reliable way to control where the shot lands. Higher resolutions like 1080p and 4k deliver more detail but take longer to generate, while 480p is the fastest choice for quick tests and iteration. Since audio is generated by default, remember to disable it if your project calls for a silent clip. Each generation also returns a seed value, which is helpful if you want to revisit or reproduce a particular result. With its combination of directed motion, synchronized sound, lip-syncing, flexible durations up to 15 seconds, and resolutions up to 4k, Seedance 2 Image to Video gives creators a single, capable tool for turning stills into finished, cinematic motion.
