更新日志

Improve dialogs #2622
Fix capture frame timestamp transfer #2620

Use Shift + mouse click/drag to move/resize segments (configurable modifier key) #517 #2595 #483
Use native web keyboard events (KeyboardEvent.code): This makes keybindings consistently independent of keyboard layout. Also don't trigger hotkeys when some UI element or dialog is focused.
New action play-selected-segments (once) #2557
Implement file name template also for merge files #2403 #2489 #2054 #2400

Many more bugfixes and improvements
Dialog buttons are now OS-dependent
Add "What's new" #669
New features 🔥
🆕 Markers: Segments that don't have any end time are now considered "markers". They are rendered differently, and are excluded from exports. Markers can be useful for bookmarking locations on the timeline and all markers can be batch exported as screenshots. More ideas for marker features are welcome!
🔈 Play multiple audio tracks simultaneously (with FFmpeg-assisted playback) #256 #936
✅ Remember segment selected/deselected state inside .llc file #1329 #885 #371

shift+alt+up Jump & seek to previous segment
shift+alt+down Jump & seek to next segment
shift+alt+pageup Jump & seek to first segment
shift+alt+pagedown Jump & seek to last segment
New action selectSegmentsAtCursor #1284 #254 (comment)
Improve waveform rendering #260
Make it faster and render around current time
Allow loading full waveform overview
Allow customising bottom waveform height
New file name template variables FILE_EXPORT_COUNT and EXPORT_COUNT #2296
Upgrade to electron v35 (drops support for macOS 10)
Upgrade to ffmpeg v7.1
More changes
Show loading indicator for mini waveform #260
change SEG_NUM and SEG_NUM_INT variables: they will now correspond to the original index of the segment as shown in the number on the segment list. new variables SELECTED_SEG_NUM and SELECTED_SEG_NUM_INT can be used for previous behavior (where the numbering is based on the segment's number in the list of selected segments).
All segments will now have a start time defined - llc project file version bumped to v2 (to migrate missing start times). Missing end time now means that the segment is a marker (previously it meant extend to end of timeline).
minor change: most operations will no longer take place if no segments selected #2335
Make "combine overlapping segments" also combine adjecent segments #2340
export confirm: allow adjusting all end frames too #2256
allow disabling remember window position closes #2240
don't create detected segments twice in mode 2, fixes #2236
