What It Does
AudioAmpToVideoSpeed links video playback speed directly to audio amplitude. When the audio gets louder, the video speeds up. When it drops, the video slows down. A slider on the audio layer controls how much the audio affects playback speed.
This creates a tight sync between audio rhythm and visual pacing without manual keyframing. The plugin analyzes the audio waveform and applies time remapping automatically.
Key Features
Amplitude-driven time remapping. The plugin reads audio amplitude values and converts them into speed changes. You control the intensity of the effect with a single slider.
Direct audio layer control. The acceleration slider lives on the audio layer itself, keeping your composition organized. Adjust the relationship between audio levels and speed without digging through effects panels.
Wide version compatibility. Works in After Effects versions from CS6 through 2025, covering over a decade of software releases.
Who It’s For
Useful for music videos, lyric animations, or any project where you want visual rhythm to match audio intensity. Saves time on projects that need tight audio-visual sync, like podcast waveforms or reactive title sequences.
Also fits workflows where you’re experimenting with different audio tracks, since the speed changes update automatically when you swap audio layers.
