Purpose and Positioning
Seedance 2.0 AI Video Generator uses text and images as a starting point to help users produce ads, Shorts, product videos, and cinematic content more quickly. Its positioning is to accelerate validation in the early stages of video production: traditional video production takes a long time in planning, shooting, editing, and revisions, while this tool can quickly generate an initial frame based on text and images, and gradually converge the creative direction around the results, making it especially suitable for advertising material testing and short video production that require comparing multiple versions. At the same time, it lowers the production barrier, requiring no professional shooting equipment or extensive editing experience; a single Korean description is enough to get started, making it quite practical for small teams and solo creators.
It should be noted that seedance-2-ai.org is an independent third-party AI video generation platform for Seedance 2.0, and is not a website operated or officially endorsed by ByteDance. It provides a Korean interface and Korean prompt guide.
Main Capabilities
- Multi-reference feature: You can upload first-frame and last-frame images to specify the beginning and end of the video; you can also additionally input reference images, reference videos, and reference audio to determine the video's style and composition.
- Audio direction control: The description mentions that it has an audio direction control feature.
- Input material formats and quantities: Images support PNG, JPG, JPEG, and WEBP, and up to 5 more can be added; videos support MP4, MOV, and MKV, up to 3, with a maximum of 50MB per file; audio supports MP3, WAV, AAC, and FLAC, up to 3, with a maximum of 15MB per file.
- Output specifications: Native support for 480p and 720p, with a 1080p output option also available; aspect ratios can be selected from 16:9, 4:3, 1:1, 3:4, 9:16, and 21:9; video length ranges from 4 seconds to 13 seconds.
- Modes: The default mode is suitable for high-quality needs such as multi-reference, audio direction, native 480p/720p generation, and 1080p output; Fast mode is a lightweight mode suitable for quick testing, supporting 480p and 720p, and 4/8/12-second lengths.
- Result handling: Generated videos can be downloaded directly or regenerated.
How to Use
- Input and references: Enter content in the text prompt, or upload images; for greater precision, you can upload first-frame and last-frame images, and add reference images, reference videos, and reference audio. All reference materials will be used to determine the video's style and composition.
- Write the prompt: Describe the scene, style, and camera move in Korean.Motion, complex shot expressions can be paired with English. For example, "a woman walking on a city street at night, close-up shot, cinematic lighting"—the more specific, the more accurate the generation. The page provides a "View Prompt Examples" button to refer to various examples.
- Select parameters: set resolution (480p/720p/1080p), aspect ratio (16:9/4:3/1:1/3:4/9:16/21:9) and video length (4 seconds to 13 seconds); choosing Fast mode lets you see results more quickly.
- Generate and iterate: click the "AI Video Production" button to start generating; results can be downloaded directly or regenerated. The official recommendation is not to change too many things at once, but to gradually fine-tune the prompt based on the generated results, for example keeping the camera movement and only changing the lighting, or keeping the product and only changing the background atmosphere.
Prompts should ideally include the subject, action, location, camera movement, lighting and atmosphere, more like a small shooting brief than a short instruction. Ad videos can describe the product's position and how the camera approaches; Shorts can describe the first-screen hook and fast motion; when using an image to generate a video, you should also specify which elements in the image need to be preserved.
Use Cases
- Ads and brand assets: turn products and brand concepts into short ads, quickly compare different message and scene directions, and test which opening is more attractive, under what background the product stands out more, and which camera movement fits the ad material better.
- Shorts and social content: quickly generate vertical video ideas, reusable content formats, and product-centered short content shots based on text or images.
- Product and e-commerce videos: use product images or detail page images to add motion around the product's form, color and usage scenarios, for exploring video directions for e-commerce, launch pages and ad testing.
- Cinematic content: specifically describe camera movement, lighting, scene atmosphere and lens texture to generate content with a more cinematic style.
- Creative validation: without shooting footage, use the text-to-video process to produce first-version samples of ad concepts, Shorts ideas and product introduction shots.
Cost and Limitations
- Cost: the official description says free credits are provided by default, and newly registered users can generate a certain number of videos for free; if you need to make more videos, you can use a paid plan, and detailed pricing and included features need to be checked on the pricing page (specific prices are not provided in the materials).
- Language: Korean prompts are supported, and complex professional camera terminology paired with English can yield more accurate results.
- Output limitations: video duration is up to 13 seconds; Fast mode only supports 480p, 720p and 4/8/12-second lengths.
- Relationship note: this site is an independent third-party platform, not a ByteDance-operated or officially endorsed website.
