v3.5.0
d5b29f4

Added

  • Audio mixer: a channel strip for every sound category, docked at the timeline's right edge (Window ▸ Audio mixer). Meters turn red when a sound gets too loud, a clip light catches peaks, and while stopped each meter shows how loud the moment under the playhead is. Faders, mute and solo per category.
  • Sound categories: Dialogue, Music, Effects and Ambience, plus your own. Route any layer (or a whole nested scene) into one; each category has its own level, effect chain, loudness target and ducking. Open a category from any layer's Sound tab to see and edit everyone in it.
  • Smart leveler: keeps every sound where its kind should sit and nothing too loud, measuring each sound once in the background. Levels by category or all together, with strength, tame-loud, lift-quiet and a speech leveler. A limiter guards the master. Turn it on or off per export.
  • Ducking rules: music gets out of the way of the voice, starting just before the first word. Any clip or category can duck under a category, a layer or a whole scene.
  • A frame's Sound tab: the comp's leveler, master, limiter and categories in one place.
  • Every comp keeps its own playhead, saved with the project. Scrubbing one scene no longer moves the others.

Changed

  • Softer typing sounds: the default keyboard click is a real click now, not a piercing tone, and export sounds exactly like playback.
  • Agents keep timelines tidy: new layers reuse free lanes, moves and trims say when a neighbour blocks, and there are page and category commands.

Fixed

  • Nested clips show the right moment at every depth: a trimmed nested clip no longer shows a later part of itself than the playhead says.
  • Editing one keyframe's scale no longer changes another. X and Y are keyed together.
  • At a cut, the selected clip's last frame shows, so you see the keyframe you're editing.
  • Shine runs edge to edge with no pause, leaves nothing parked after a single pass, and its position can be keyframed.
  • Filled paths no longer get a surprise outline; keyframed fonts load; groups can be animated by agents.
  • No click when a sound is cut off by the end of its scene in exports.
  • Frame titles, guides and handles stay sharp at 1/2, 1/4 and 1/8 preview resolution — only the artwork softens.
  • Shadows, blur, glow and boil stay crisp when you zoom in, including on nested scenes. Grain, halftone and pixelate still match the exported pixels.
  • A video's own sound goes through the mixer while playing — its category, the leveler, ducking and the meters.
  • Motion blur strength and shutter can be animated, and agents can set them.
  • Styled text after a counting number stays put: "+" styled after "0" is still the "+" after "40".

Installing

macOS

AtomCut is not yet notarized, so on first launch Gatekeeper will say the app
"is damaged and can't be opened" or "cannot be opened because the developer
cannot be verified." This is expected for unsigned builds. After dragging
AtomCut into Applications, clear the quarantine flag once:

xattr -cr /Applications/AtomCut.app

Then open it normally. (Alternatively: right-click the app → Open → Open.)

Windows

SmartScreen may warn on first run. Choose More info → Run anyway.

Linux

  • AppImage: chmod +x AtomCut-*.AppImage && ./AtomCut-*.AppImage
  • Debian/Ubuntu: sudo dpkg -i AtomCut-*.deb

Once installed, AtomCut keeps itself up to date automatically — new versions are
offered in-app and install on relaunch.
