Cock hero maker - beat meter, rounds and beat-synced cuts in one app

Cock heroes are rhythm-based videos where the viewer follows a visual pace synced to music. Creating one requires precise audio-visual sync, carefully timed clip transitions that escalate with the song's energy, and a lot of patience in a traditional editor. Onset Engine's beat detection automates the hardest part.

What is a Cock Hero?

A cock hero combines video clips edited to music with pacing that builds through the song - slow sections during verses, intense rapid cuts during drops. Viewers follow the visual rhythm. The challenge escalates with the song's intensity. Cock heroes often run well past a single song and use songs with dramatic energy variation.

Why Onset Engine for Cock Hero?

Onset Engine now builds the whole cock hero, not just the cuts. It detects every beat and bar of your songs, cuts your clips on them, and draws a rhythm bar into the video: cues slide to a target and land on it exactly as each beat sounds (Lane, Falling or Pulse style, every beat, half-time, double-time or downbeats only). Rounds turn each song into a round with its own pace and beat pattern, a silent break with a 3-2-1 countdown, and a title card; a label warns just before the beat pattern changes. Add a click track if you like, and set the total running time with Length. The hardest parts - hundreds of beat-perfect cuts and a meter that matches them - are automatic.

Tips for Cock Hero content

• Choose songs with clear tempo escalation - the AI maps energy curves automatically, giving you natural difficulty progression.
• Use longer source clips so the AI has more material to work with for the extended duration cock heroes need.
• Turn on the rhythm bar under More options and preview the draft: the bar is drawn into drafts too, so you can try Lane, Falling and Pulse before the full render.
• The Re-Roll curator tool is great for swapping out clips that don't match the intensity you want in specific sections.
• Cock heroes run long, which means hundreds of manual beat placements in a traditional editor - this is the part worth automating.

Music recommendations

EDM with clear buildups and drops works best. Dubstep gives you obvious intensity changes. Tracks with tempo variation (slow verse, fast chorus) create natural difficulty curves. Avoid songs with flat energy - you need contrast.

Common mistakes to avoid

• Using one short song for a long session - add several songs as rounds, or set Length (e.g. 15 min) and your songs repeat until it is that long.
• Changing the beat pattern without warning - when a round switches to double-time or half-time, Onset Engine shows a label just before it; keep breaks between big changes.
• Flat energy songs with no variation - the whole point of a cock hero is escalating difficulty, which requires songs with quiet sections AND intense drops.
• Too few clips for long-duration videos - a long cock hero needs plenty of source clips to avoid visible repetition.
• Skipping the preview step on long renders - a 12-minute export takes time. Preview first to catch issues before committing to the full render.

What you'll still do manually

The rhythm bar comes in three styles and five colors rather than a meter you draw yourself, and its beat patterns are every beat, half-time, double-time, downbeats only or rest (no custom stroke patterns). On-screen text is limited to round titles, countdowns and the bar's own labels; free text instructions anywhere on the timeline still need an editor. Rounds, Length and the energy arc need Core ($29.99); the rhythm bar and click track work on every plan, including the free demo.

Compared to other Cock Hero tools

• Manual in Premiere or Resolve — Full control, but many hours per video placing hundreds of beats by hand.
• Onset Engine + a free editor — Cuts, beat meter, rounds and countdowns in one app; render and you are done.
