Prerequisites

To get started with Text2video Zero, you'll need a Cognitive Actions API key and a basic understanding of how to make API calls.

Generate Video from Text Zero-Shot

This action utilizes the Picsart Text2Video-Zero model to generate videos based on textual prompts. It effectively solves the challenge of video content creation by eliminating the need for large-scale video datasets and heavy computational resources, making it accessible for developers at any level.

Input Requirements

The action accepts a CompositeRequest object containing the following parameters:

  • Prompt: A descriptive text that guides the video content (e.g., "a beautiful sunset, clouds").
  • Seed: Optional parameter for deterministic results.
  • Chunk Size: Number of frames processed at once (range: 1-10; default: 8).
  • Resolution: Output video resolution (default: 512 pixels).
  • End Timestep: Ending timestep for DDPM steps (default: 47).
  • Video Length: Total number of frames in the video (default: 8).
  • Merging Ratio: Compression ratio for merged tokens (range: 0-0.9; default: 0).
  • Start Timestep: Starting timestep for DDPM steps (default: 44).
  • Negative Prompt: Elements to avoid in the video.
  • Frames Per Second: Frame rate for the video (range: 5-60; default: 15).
  • Motion Field Strength X: Motion field strength along the X-axis (default: 12).
  • Motion Field Strength Y: Motion field strength along the Y-axis (default: 12).

Expected Output

The expected output is a link to the generated video, which can be accessed directly. For example, a successful invocation may return a URL like: https://assets.cognitiveactions.com/invocations/14cf9e92-8284-4209-9e31-5794c4f6e24e/6e7c0041-8864-4a55-97cd-15a5410c3ffd.mp4.
