Create a Lifelike Sound using HunyuanVideo Foley

49

Overview

HunyuanVideo-Foley is Tencent’s state-of-the-art, open-source AI system for generating Foley sound lifelike audio effects that are synchronized precisely to video content. Leveraging multimodal diffusion transformers, large-scale data curation, and advanced latent alignment, this tool automatically creates high-fidelity, context-aware Foley audio for everything from silent AI-generated clips to complex film, gaming, or advertising projects.

Key Features

  • End-to-End Foley Synthesis: From silent or original videos, HunyuanVideo-Foley automatically generates professional-grade synchronized audio effects such as footsteps, doors, ambient noises, and action sounds removing the need for manual SFX editing or laborious sound library searches.​​

  • Multi-Scenario Adaptability: Ideal for short videos, feature films, advertisements, and game content, thanks to robust support for diverse visual scenes and cues.​​

  • Scalable Multimodal Pipeline: Trained on over 100,000 hours of video, audio, and text pairings, the model uses automated scene detection, audio annotation, and semantic captioning to ensure broad coverage and balance across content types.​

  • Semantic-Temporal Precision: Dual-stream transformer architecture interprets both visual and textual instructions, fusing them via cross-attention with tight event-level temporal synchronization—resulting in sound effects that match not just the timing, but also the intent and emotion of each scene.​

  • High-Fidelity Output: Employs a 48kHz audio variational autoencoder for professional quality; audio output is suitable for production-grade use in film, broadcast, or interactive media.​

  • Open-Source & Efficient: Designed for ease of use, rapid synthesis, and seamless integration into automated video workflows; democratizes high-level sound design for all creators, not just studios.

Who Benefits

  • Video Content Creators: Elevate short clips, vlogs, documentaries, or feature films with instantly tailored sound design.

  • Filmmakers & Game Developers: Replace manual SFX workflows with scalable, context-aware sound generation.

  • Advertisers & Marketers: Synchronize product or event videos with immersive, professionally-matched audio cues.

  • AI Developers & Researchers: Integrate advanced auditory intelligence into creative and research pipelines with open-source flexibility.
