Usage Methodology

Step 1: Upload Your Video

Begin by uploading the video file you want to enhance with sound. MMAudio supports common video formats. The model will analyze the visual content to generate context-aware audio.

Step 2: Set Your Audio Preferences

Customize the audio generation with the following parameters for optimal results:

Model Tips:

• Describe the type of sound or atmosphere you want for your video (e.g., "waves and seagulls on a beach" or "intense sci-fi battle")
• Leave blank for automatic matching based on video content

Negative Prompt:

• Specify what you do NOT want in the generated audio (e.g., "no music" or "no human voices")
• This helps refine the output quality

Seed:

• Set a numerical value for reproducible results
• Use -1 for random generation each time

Num Steps:

• Controls the number of inference steps for audio generation
• Higher values typically produce better quality but require more processing time
