The LAS Enhanced Video Generation/Basic Video Generation service is built around the Seedance 2.x series models, and enhances both the pre-processing and post-processing workflows for video generation. It integrates capabilities such as video format conversion, video segmentation, Video Inpaint, subtitle generation, Audio and Video Merge, Video Super Resolution, and more, expanding the boundaries of video generation models, improving the quality and duration of generated videos, reducing token consumption costs, and helping customers increase production efficiency.

Application scenarios #

As a general-purpose large video generation model, Seedance can be flexibly applied to a wide range of video generation scenarios. For example:

• Marketing and promotional videos: product promotion, brand advertising shorts, event or holiday marketing content. Supports direct generation from text or images, suitable for high-frequency, batch material production.
• Short video content production: Douyin/Video Account/Bilibili content, MCN batch production, rapid content creation for individual creators. Provides generation, editing, and extension capabilities, with an emphasis on style, camera movement, and character stability control.
• Image-to-video / photo animation: converting static posters to dynamic content, dynamic interpretation of product or character images, animating old photos or illustrations. Supports text-to-video and image-to-video; some versions support control of the first and last frames.
• Video editing and remixing: re-editing, video extension, stylization, multi-source merging. The 2.x series explicitly supports video editing and extension, not just generation from scratch.
• Education and knowledge expression: course explanation shorts, animated picture books or science popularization, teaching demonstration videos. Visualizes abstract knowledge or script content to improve communication efficiency.
• Digital human / character consistency content: virtual anchors, virtual idols, digital humans for enterprise training. Ensures stable character features, object detail, and style restoration capabilities.
• E-commerce and livestreaming materials: product display videos, virtual scene demonstrations, livestream room warm-up or clips. Enables large-scale, rapid, and low-cost material production, highly suited for e-commerce scenarios.

• Billing standards

  Breakdown items	Billing standards description
  Billing item	Duration of input/output video.
  Billing type	Usage-based billing, unit: CNY/second, billed hourly based on actual billing usage.
  Unit price	Depends on the algorithm version you select (Basic Edition, Enhanced Edition).

  warning

  • Total cost paid: In addition to the unit price, it also depends on the duration of the input/output video and the resolution of the input/output video.
  • Only tasks that successfully generate videos will incur charges. Scenarios where video generation fails due to review or other operational reasons will not be charged.

• Billing details
  Estimated billing: Total cost ≈ unit price * billing quantity = unit price * (input video duration + output video duration)

  warning

  The above formula is for cost estimation only. Actual billing is based on the bill.

• Billing example

  • Example scenario: Video generation using the enhanced version (Seedance 2.0), with input including a reference video (duration: 5 seconds), output video duration of 7 seconds, and resolution of 1080p.
  • Cost details:
    Total cost ≈ unit price * billing quantity = 3.014 CNY/second * (5 seconds + 7 seconds) = 36.168 CNY
