Eight visualizations, full control over color and motion, and a deterministic MP4 out the other side. Runs entirely in your browser — your audio never leaves the tab.
Drop a track, pick the Lyric Card or Caption Strip preset, type your title — done. The classic YouTube/TikTok lyric video, without the After Effects.
Pull a 30-second pull-quote, render bars or a waveform, drop it on social. Same engine that powers HyperFrames' CLI handles longer renders if you outgrow the browser.
A square 1080×1080 vinyl loop with your title in the center. Looks like a label release. Renders in under a minute for short clips.
Every visualization reads from a pre-baked timeline — per-frame FFT magnitudes, loudness, and onset strength — computed once from your audio with OfflineAudioContext. That means the renderer never reads the audio clock or requestAnimationFrame. Frames are indexed by integer frame number, so two runs of the same configuration produce byte-identical MP4 output. This is the same principle behind the HyperFrames CLI — your in-browser export and a server-side render of the same composition look the same.
The in-browser tool maxes out around a few minutes. The HyperFrames CLI renders the same compositions, just bigger and faster — and pipes straight into your CI.
