LosslessCut 3.65.0

LosslessCut

LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.

Features

Quickly cut a file by its MP4/MKV chapters
Quickly cut a YouTube video by its chapters (or music times from a comment)
Change the language of a file's audio/subtitle tracks
Attach cover art to videos

Fix rotation of a video that has the wrong orientation flag set
Great for rotating phone videos that come out the wrong way without actually re-encoding the video.

LosslessCut 3.65.0 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
Split timeline by byte size #1219
Modify segments by JavaScript expression #2128 #2305
Black/scene/silence detect
Remember dialog parameters (for current LosslessCut launch) #371 #2257
Allow selecting which audio/video track to use (current preview track) #2354
Streaming segment detection #2325
New shortcuts #2289
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
improve segment list buttons
log more ffmpeg commands to cli
make playback rate indicator pop (when changing) - customer thought it was hard to see currently
implement CMX3600 EDL import #1340
import PBF as markers #993
fix webp on mac #1671
fix broken loop selected segments
Also: Removed old csv project auto import
Allow extracting markers as images
improve loader
fix time input placeholder #2346
