Versie 3.70 van LosslessCut is uitgekomen met meteen een kleine bugfix erachteraan. LosslessCut is een crossplatform- en opensourceprogramma waarmee stukken uit video's kunnen worden geknipt. Dit doet het zonder dat de video's worden gedecodeerd en weer gecodeerd, dus het werkt snel en zonder verlies van kwaliteit. Het is ideaal om minder interessante delen uit geschoten beelden van actioncamera's of drones te verwijderen. Ook is het mogelijk om jpg-afbeeldingen van scenes van de video te maken. De changelog voor deze uitgave ziet er als volgt uit:
Changes in LosslessCut 3.70.1Changes in LosslessCut 3.70.0
- (Windows) Fix FFmpeg missing from the x64 build #3147
Bug fixes:
- Upgrade bundled FFmpeg to 8.1 (fixes CVE-2026-8461) #2943 #3139
- New "Theme" setting (System default / Dark / Light) - LosslessCut can now follow the OS dark/light theme #3113
- Metadata editor improvements #3135 #3136 #3140 #3141
- Copy track or file metadata from another track or another loaded file with the new "Copy from" menu
- Apply a track metadata value (e.g.
language) to all other tracks of the same type with one click- Edited tracks and files are now highlighted in the tracks dialog, and changes can be reset per track, per file or all at once
- Suggestions for common codec tags (e.g.
hvc1for Apple compatibility), language codes and metadata keys (title,language,handler_name), with warnings for invalid values- "Now" button for
creation_time, multi-line editing forcomment/description, Esc to cancel an edit, and a notice when MP4/MOV may drop custom keys- Export dialog warns when an HEVC track will lack the
hvc1tag needed for Apple devices- New setting "Video preview scaling" (advanced), e.g. to not upscale small videos #3125 #3134 (based on #3132)
- The Change FPS dialog now accepts fractions like
30000/1001#2492- Register
.llcproject files, so they can be double-clicked to open in LosslessCut (Windows, macOS) #3070- (Linux) LosslessCut can now be chosen as "Open with" app for video and audio files (AppImage, snap) #288
- (Linux) AppImage no longer requires libfuse2 #3022
- Press Escape to leave an input field (or Enter to commit a cut time), so that keyboard shortcuts work again #2942
- Inserting a variable or resetting the output file name template can now be undone #3017
- Ctrl+Q now quits LosslessCut on Windows and Linux #2136
- Trackpad pinch zooms the timeline faster, and Shift now works as the mouse wheel zoom modifier #3118
- Show a subtle timeline progress indicator in fullscreen
- Bring back the time display when hovering the timeline
- Track import, subtitle and project import dialogs now open in the folder of the current video #3088 #3019 (#3096)
- Show sample rate (kHz) instead of frame rate for audio tracks in the tracks dialog #3099
- Improve contrast of the timeline cursor and keyframes on top of segments #1199
- Add GitHub link in the Help menu #2950
- Pull latest translations
Other notable changes:
- Compensate for FFmpeg seeking too early in MKV/WebM files with B-frames, which made keyframe cuts start from the previous keyframe (tested on synthetic files, feedback welcome) #1216 #2804 #3131 (thanks to #1984 for the investigation)
- Fix audio-only (e.g. M4A) cuts starting several seconds early/late for files that only flag some audio packets as keyframes #3087
- Fix wrong duration of exported segments when cutting a file with cover art (e.g. split M4A audiobooks) #3009
- Fix playback and "convert to supported format" of audio with unknown/non-standard channel layouts (e.g. DV/DVCPRO
.mov) #3038- Fix black/silent scene detection finding nothing with FFmpeg 8.1
- Fix audio continuing to play after closing a file #2907
- Fix file modification time of smart cut output (it was up to one keyframe interval off) #3116, and of fully re-encoded segments (lossy mode) #3067 (thanks @mklaber #3068)
- Fix export failing when a segment label contains characters that are invalid in file names (e.g.
:) and "Sanitize file names" is off #2986 #3121, or control characters on Windows #3123- Fix file name sanitizer not replacing
/and some punctuation #2982 (#2983)- Long output file names no longer lose their file extension when truncated, exporting segments from files with very long names no longer produces duplicate names, and long non-Latin names are truncated correctly #2171 #3114 #3115
- Fix chapters having zero length, or missing when an input chapter has no title, when merging files that already have chapters #3124
- The merge compatibility check no longer warns about small differences in average frame rate #2759
- When the custom merge output file name template is invalid, the fallback name no longer says "cut-merged" #3115
- Fix typed cut times being lost when using frame or seconds timecode formats #2969 #3129; cut time inputs now keep the typed time when clicking elsewhere (Escape still cancels) #3133
- Fix importing Final Cut Pro / DaVinci Resolve XML files with only one clip or whole second times #3127
- Fix mouse wheel zoom direction (wheel up / pinch out zooms in again) #2962, and mouse wheel seeking sometimes stepping backwards #3118
- OS media keys no longer interfere with playback, and no empty media control is shown in the OS #3028
- The "hevc_mp4toannexb" track option toggle now correctly shows whether it is enabled #3135
- (Linux snap) Fix crash on startup #3002 #3026
- (Windows) Show a proper "FFmpeg executable not found" error instead of an error report when the (custom) FFmpeg executable is missing #2993
- Show a clear error when the source file was moved/deleted before extracting frames or tracks #3023
- Fix digits being laid out vertically instead of horizontally (regression in 3.69.0) #2911
- Simple mode: improvements, and no longer overwrite the merged files name template #2927
Dev:
- "Create segments from keyframes" moved from the Tools menu to the Segments menu #3074 (#3092)
- "Remove selected segments" moved to the bottom of the segments context menu, to avoid accidental clicks
- HTTP API: requests coming from a web browser (with an
Originheader or a non-localhostHostheader) are now rejected, to prevent websites from controlling LosslessCut. See API docs- CLI: relative file paths are now resolved correctly when LosslessCut is already running #1571 #3104 (based on a patch by Bell)
- CLI:
--keyboard-actionarguments now accept JSON5 and are validated, and no longer try to open their arguments as files when no instance is running #3108;--settings-jsonis now validated and invalid input is ignored instead of being written to the config #3106- Security hardening: disable the RunAsNode and other unneeded Electron fuses #3059
- Upgrade Electron to 42.11.15 (security fixes), and fix the tar decompression DoS vulnerability in build dependencies
- Many other improvements and fixes
