SEEDANCE 2 IMAGE TO VIDEO

Seedance 2 Image to Video is ByteDance's most advanced video generation model, purpose-built to transform your still images into cinematic, dynamic video clips with remarkable fidelity. Whether you're a filmmaker previewing a scene, a designer animating a concept, or a content creator bringing social media posts to life, Seedance 2 offers a powerful creative pipeline that starts with a single image and a text prompt describing the motion and action you envision.

At its core, the model takes two inputs: a starting image and a descriptive text prompt. You upload a still frame — a photograph, illustration, digital painting, or any visual — and then write a prompt that tells the model what should happen in the video. The prompt describes the desired motion, action, and narrative. For example, you might upload an image of an octopus on the ocean floor and prompt the model with a story about it finding a football and calling friends for an underwater game. The model interprets both the visual content of your image and the narrative direction of your text to generate a cohesive, fluid video.

One of Seedance 2's standout creative features is its native audio generation. By default, the model produces synchronized audio alongside your video, including sound effects, ambient sounds, and even lip-synced speech. This means you don't need to layer in audio separately — the model intelligently generates a soundscape that matches what's happening on screen. If a character is speaking, the audio will attempt to sync with their lip movements. If the scene is set in a forest, expect ambient nature sounds. You can also choose to turn audio generation off if you prefer to work with silent footage and add your own sound design later.

Another powerful capability is the start-and-end frame control. In addition to providing a starting image, you can optionally supply an ending image. When you do, the model generates a video that smoothly transitions from your first frame to your last frame, giving you precise control over the beginning and end states of your animation. This is invaluable for creating seamless morphs, transformation sequences, or ensuring a video lands exactly where you need it — perfect for storyboard-driven workflows or looping content.

Seedance 2 offers flexible aspect ratio options to suit virtually any project format. You can choose from landscape (16:9), portrait or vertical (9:16), square (1:1), ultrawide cinematic (21:9), standard (4:3 and 3:4), or let the model automatically infer the best aspect ratio from your input image. This makes it equally at home producing widescreen cinematic sequences, vertical social media reels, square posts, or ultra-panoramic visuals.

Video duration is highly customizable, ranging from 4 seconds up to 15 seconds. You can set a specific length or choose the automatic option, which lets the model decide the ideal duration based on the complexity and content of your prompt. This flexibility is great for everything from quick social media loops to longer narrative clips that need room to breathe.

Resolution options include 480p for faster generation when you're iterating on ideas or need quick previews, and 720p for a balanced combination of quality and speed suitable for polished output. The model supports JPEG, PNG, and WebP image formats as inputs, with a generous maximum file size of 30 MB per image, so you can work with high-quality source material.

The model is especially well-suited for stylized content, visual transformation, and lip-sync projects — making it a go-to choice for creative work that demands expressive, cinematic motion. Whether you're crafting stylized animations, transforming static artwork into living scenes, or generating talking-head content with synchronized audio, Seedance 2 is designed to deliver director-level results.

For reproducibility, you can set a seed value to generate similar results across multiple runs. While results may still vary slightly even with the same seed, this feature is helpful when you want to explore variations on a theme or maintain consistency across a series of related videos.

The model's real-world physics simulation and director-level camera control mean that generated videos exhibit natural, believable motion. Objects move with weight and momentum, environments respond realistically, and camera movements feel intentional and cinematic rather than random or artificial.

Seedance 2 Image to Video is ideal for a wide range of creative professionals. Filmmakers can use it to pre-visualize scenes and generate animated storyboards. Illustrators and concept artists can bring their static work to life for portfolio pieces or client presentations. Social media creators can quickly produce eye-catching vertical video content. Animators can use the start-and-end frame feature to control transitions with precision. And anyone working in content production can leverage the built-in audio generation to create complete, ready-to-share video assets from a single image and a few lines of descriptive text.

In summary, Seedance 2 Image to Video combines image-driven animation, natural language direction, native audio synthesis, flexible formatting, and physics-aware motion into a single, accessible creative tool — making it one of the most versatile and powerful image-to-video models available for creative professionals today.
