Changelog

v1.1.2

August 24, 2026

Dramatically smoother playhead scrubbing — After Effects’ playhead now keeps pace with your mouse instead of lagging behind and drifting after you release.
Faster timeline and waveform rendering — large comps render more smoothly.

Alt-click an A/V clip to select just its audio or video component, then delete it without only muting or hiding that component.
Fixed the vertical scrollbar thumb so it scales correctly in timelines with more than about 25 tracks.
Shift-scrubbing with snapping now lands After Effects’ playhead on the snapped frame.
Alt-slip and Alt-slide on an A/V clip no longer move the untouched half to track 1.
Ripple trims now respect locked clips and cannot push downstream clips on top of them.
Arrow keys, Home, and End during RAM preview now stop playback and move the playhead without desynchronizing it.
Fixed a failed rolling edit on a J/L pair corrupting After Effects’ undo history for the rest of the session.
Fixed rare cases where Add Edit on the fly or dragging from the Project panel could undo an unrelated edit.
Failed operations now show an error and resync the timeline instead of failing silently.
If After Effects hiccups while Railcut reads a comp, the timeline stays visible instead of going blank.

On partially locked tracks, Select All + Delete now removes the selected components instead of only disabling their switches.
Keyframe edits made directly in After Effects refresh in Railcut when you return to the panel, rather than only on hover.

Linked Track Switching — optional Wrench menu toggle that mirrors vertical track moves onto linked A/V partners. Drag video up two tracks and its linked audio moves up two audio tracks when possible.
Configurable Play / Pause shortcut — Play / Pause is now a normal shortcut action. Space remains the default, but it can be reassigned, saved in custom presets, exported, and imported from compatible AE shortcut files.

Fixed a crash that could happen after duplicating a layer directly in the After Effects timeline and returning to Railcut.
Fixed an empty-track regression related to duplicated AE layers.
Fixed reversed clip behavior: waveforms now draw, slip editing no longer collapses clips to a single frame, and media-limit corner flags respect negative stretch timing.
Fixed the macOS license storage path from v1.1.0 and added automatic migration from the temporary doubled path.
Improved license recovery for stale activation instances and made Use a different key available in more non-active license states, including Grace Period.

Unlink and relink clips — use the clip right-click menu or Ctrl+L to unlink or link an A/V pair.
Single-side A/V editing — hold Alt with most edit tools to act on only the video or audio side of an A/V pair
Out-of-sync indicators — linked pairs that are offset from each other show a sync badge with the amount of drift
Clip groups — group selected clips so they select and move together
Close Gaps — remove gaps in a selection or timeline section from the wrench menu
Blending Modes — change a clip’s blending mode from the right-click context menu
Keyboard shortcut persistence — custom shortcuts now save to disk and survive Railcut updates
Shortcut import/export — export a custom shortcut preset to JSON or import one from another machine
After Effects shortcut pull — Railcut can transfer compatible shortcuts from After Effects

Better Add Edit precedence — Ctrl+K prioritizes selected clips when a selection exists, then falls back to targeted tracks
Empty-state improvements — the wrench and bell button now display even when a timeline isn’t open
Footage panel in/out marks — dragging from the Project Panel now respects footage panel’s in/out ranges

Fixed stale license instance recovery so Railcut can recover from outdated activation IDs
Fixed linked A/V overwrite, paste, duplicate, trim, slip, slide, ripple, rate stretch, and blade edge cases
Fixed track assignment stability across undo/redo, comp switching, paste operations, and linked-pair edits

Tool shortcuts — editing tools can have keyboard shortcuts, and the active tool shortcut displays in the toolbar
Middle mouse button panning — horizontal and vertical timeline panning
Select Clip at Playhead (D) — selects clips under the CTI on targeted tracks
Mark Selection (/) — sets the comp work area in/out points to span the selected clips, matching Premiere Pro’s behavior
Rename Selected Clip (Enter) — inline rename for the selected clip
Precompose Clips — right-click selected clips to precompose them directly from the timeline
Double-click to open source — double-click a footage clip to open it in AE’s Layer panel; double-click a precomp to open it in the viewer
Selection sync — toggle in the Wrench menu to automatically sync the Railcut selection to AE layers; or use the push command for on-demand sync (Shift + G)
Still image duration — set the default duration for still images dragged onto the timeline (Settings → Preferences)
Separate keyframe line toggles — opacity and audio keyframe lines have independent visibility toggles

Waveform performance — major performance improvement for timelines with many clips
Live waveform updates — waveforms, keyframes, and markers shift live during ripple, slide, slip, and move drags
Live rubber band updates — waveform amplitude updates live while dragging rubber band handles
Source-accurate thumbnails — clip thumbnails use the source file’s native aspect ratio; vertical and square clips display with letterbox/pillarbox instead of being stretched to fit the comp
CTI scrub auto-scroll — the timeline scrolls while dragging the playhead near the canvas edges

Fixed Unicode username path bug affecting Windows users with accented characters in their system username
Fixed CTI scrub auto-scroll triggering too early; it now scrolls at canvas edges
Fixed inconsistent minimum track height across different display scaling settings
Fixed double-click opening the AE Footage panel instead of the Layer panel
Improved license activation error messages for SSL/network failures so corporate firewall and timeout errors show plain-English guidance
