Input Requirements

This action requires the following inputs:

  • Video URI: The link to the video file from which you want to generate audio.
  • Prompt: A text description that guides the audio generation process.
  • Duration: The length of the generated audio in seconds (minimum 1 second).
  • Number of Steps: The number of inference steps for audio generation, which can improve quality.
  • Negative Prompt: Specifies sounds to avoid in the generated audio.
  • Guidance Strength: The influence strength of the provided prompts during audio generation.
  • Seed (optional): A random seed for generation (leave blank to randomize).
  • Image URI (optional): For experimental use, an image that can affect audio generation.

Expected Output

The output will be a generated audio file that complements your video content, enhancing the overall viewing experience. You will receive a URI link to the generated audio.

Use Cases for this specific action

  • Content Creators: Quickly add soundtracks to video content for social media, YouTube, or presentations without extensive audio editing.
  • Game Developers: Generate ambient sounds or background music that aligns with gameplay visuals, enriching player immersion.
  • Advertisers: Create tailored audio for promotional videos that resonate with the targeted audience and elevate brand messaging.
