Generate and Edit Videos with VideoCrafter2

The Generate and Edit Videos with VideoCrafter2 action empowers developers to create high-quality videos by leveraging textual prompts and images. This action addresses the challenge of video content creation by allowing users to generate videos that adhere closely to their specified themes and styles.

Input Requirements

The action requires a structured input object that includes:

  • Prompt: A textual description guiding the video generation process. For example, "With the style of van Gogh, A young couple dances under the moonlight by the lake."
  • Guidance Scale: A numerical value that determines how closely the output adheres to the prompt. Higher values yield more accurate representations of the desired content.
  • Denoising Steps: This integer defines the number of steps in the denoising process, which directly affects the quality of the output video.
  • Frame Rate: Specifies how many frames per second will be saved in the final video.

Example input:

{
  "prompt": "With the style of van Gogh, A young couple dances under the moonlight by the lake.",
  "guidanceScale": 12,
  "denoisingSteps": 50,
  "saveFramesPerSecond": 10
}

Expected Output

Upon successful execution, the action returns a link to the generated video. For example: https://assets.cognitiveactions.com/invocations/a79cab40-37f4-42e6-a542-86fcaa304851/590180d2-1360-47dd-a99a-eda264c945bf.mp4

  • Artistic Projects: Produce unique artistic videos inspired by famous painters or styles, allowing for creative expression in a digital format.
