PRODUCE

A music bed that gets out of the way of the voice.

The Audio & Music panel has three boxes: a track under the whole video (from the library, or composed from your words), music composed for one part to its exact length, and a box that fixes the sound in one part — a sound effect, or a fade, duck or mute described in plain words. Beds loop, fade and duck under every narration clip and recorded voice, and on export the whole mix is normalised to a platform loudness target — YouTube by default.

What it does

The detail that makes it work.

Whole video or one part

A library or composed bed under everything, or a track composed for the clips or range you picked, placed right there.

Fix the sound in words

“A gentle whoosh”, “fade the music out here”, “quieter under this part” — the narration itself is never touched.

Ducking from one curve

The preview and the render share the same gain curve, so the mix you hear is the mix you ship.

Loudness normalised

Two-pass loudness on every export path, with a report stored alongside the render.

Video editorDescribe an edit in words, edit the video by editing its text, cut any range — on a real multi-track timeline.AI editChange the video in plain words — transitions, animations, zooms, filters, speed, titles and shapes.Ranges & selectionsIn and out points, ripple delete, keep-only, group moves, trims and a menu on every clip.RecordingMulti-source recording — screen, camera, or both, with advanced options.AI magicTurn a rough recorded take into a polished one: AI tidies the transcript, you review it, and it is spoken again in the voice you pick.Rendered from your sourceFormulas, code and diagrams are drawn from your source in code, so the same scene renders the same frames every time.Transitions, keyframes & speed rampsCut transitions, position/scale/rotation/opacity keyframes and variable speed — shared by the preview and the render.Chapters, markers & VTTTimeline markers become embedded MP4 chapters, a pasteable YouTube list, and VTT captions.Auto zoom & cursor from your clicksThe Cutaway extension logs pointer moves and clicks while you record; the editor turns them into zooms, click rings and a clean synthetic cursor.Masks, chroma key & filtersEllipse, rounded and inset masks with feathering; a green/blue-screen keyer; colour filters — all rendered identically in the MP4.Named versions & restoreWhole-timeline snapshots with a readable diff, taken by you or automatically before every export and re-prep.Edit one scene, re-voice one sceneRe-opening a changed lecture in Studio re-synthesises only the scenes whose narration changed and merges your timeline instead of clearing it.
