Why use Hunyuan Video Foley for video?
Automatic sound effect generation synced to on screen motion
Hunyuan Video Foley analyzes movement in the video and generates matching sound cues ( footsteps, impacts, object interactions ). This creates more immersive clips without manual audio design.
Material and environment aware foley that fits the scene
The model adapts sound based on the visual context, producing more believable effects that match surfaces, lighting, and action. It is ideal for polishing gameplay style ads, feature demos, or cinematic loops.
Fast, iteration friendly audio passes for UA and LiveOps videos
Hunyuan Foley produces complete audio layers quickly, which helps teams test multiple creative approaches. It reduces the time spent on sound design for short form content and allows rapid experimentation with different moods or pacing.
Adding dynamic sound effects to UA videos and promotional clips
Enhance motion driven ads with synced sound cues that make actions feel more impactful. Hunyuan Foley is ideal for short loopable videos where sound clarity improves engagement.
Quick audio passes for character or cosmetic showcase videos
Automatically generate subtle foley details ( cloth movement, footsteps, weapon handling ) that make character clips feel more polished. Great for LiveOps skin reveals or shop animations.
Ambient sound generation for environment and mood videos
Produce environmental audio ( wind, soft ambience, light interactions ) to support biome reveals or thematic event teasers. Hunyuan Foley helps create atmosphere without manual sound layering.
FAQ

How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
