BeatMarker Pro

AI Music Analysis

Four analysis tiers from local Web Audio onset detection through Google Gemini Flash 3 multimodal deep analysis. Picks the right tool for the cut.

Section-Aware Markers

8-colour section-aware markers (verse / chorus / drop / buildup / bridge / intro / outro), confidence-gated section boundaries, peak-emphasis markers at the true emotional climax of each section.

Stems & Loops

4-stem and 6-stem demix (vocals / drums / bass / other / guitar / piano), drum-stem backing track, auto and manual loop generation with snap-to-downbeat.

Premiere Native

Sample-accurate metronome, four click-track import modes, beat-snap clip cuts, sequence + clip markers, sidecar JSON for portable analysis. CEP 11 panel — installs and updates cleanly.

Music Video Editors

Cut to the beat, drop to the drop, hit every chorus. BeatMarker places the markers and distributes your b-roll one-per-marker — filter by marker type so clips land only on choruses, only on drops, or only on every-Nth beat. Bypasses Premiere's stock Automate to Sequence (which uses every marker uniformly) so you stay in control.

Trailer & Promo

Find the buildup, mark the drop, surface the peak-confidence emotional climax. Section-coloured markers make song structure visually obvious in the timeline ruler.

Lyric & Karaoke

Whisper-powered lyrics layer puts a Premiere marker per line or per word, section-coloured, optionally beat-snapped, with confidence filtering. Skip the manual transcription pass.
