Model overview

mmaudio-t4 provides cost-optimized video-to-audio synthesis using T4 GPU hardware to reduce computational expenses while maintaining high-quality audio generation. This model represents a budget-friendly implementation of the MMAudio V2 architecture, which uses multimodal joint training to generate synchronized audio from video content and text prompts. Unlike the standard mmaudio version, this T4-optimized variant prioritizes accessibility through lower hardware requirements. The model builds on research from taming-multimodal-joint-training-high-quality-video and competes with other audio generation tools like thinksound, which uses reasoning-based approaches. Created by zsxkib, this implementation makes professional video-to-audio synthesis more accessible for developers and content creators working with budget constraints.

Model inputs and outputs

The model accepts video files, text prompts, and optional images to generate contextually appropriate audio. Users can control the generation process through guidance strength parameters, inference steps, and duration settings while providing negative prompts to avoid unwanted sounds.

Inputs

video: Optional video file for video-to-audio generation
prompt: Text description for desired audio content
image: Optional image file for experimental image-to-audio generation
negative_prompt: Text describing sounds to avoid (defaults to "music")
duration: Output length in seconds (1-infinity range, defaults to 8 seconds)
num_steps: Number of inference steps for generation quality
cfg_strength: Guidance strength parameter (1-infinity range, defaults to 4.5)
seed: Random seed for reproducible results
