Download LosslessCut 3.49.0 Download | TechSpot

LosslessCut is great for rough processing of large video files taken from a camcorder, GoPro, drone, etc.

Lets you quickly extract the good parts from your videos and discard GB of data without losing quality. It does no decoding/encoding and is therefore extremely fast. Also allows taking JPEG image of the video at the selected time. This app uses the awesome ffmpeg to do the grunt work. Also supports lossless cutting in the most common audio formats.

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. Its main function is lossless trimming and cutting of video and audio files, which is great for saving space by rough cutting large video files taken from a camcorder, GoPro, drone, etc. It allows you to quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encoding and thus losing quality. Or you can add a music or subtitle track to your video without coding. Everything is extremely fast because it does an almost direct data copy, powered by the amazing ffmpeg that does all the grunt work.

Properties

• Lossless cutting of most video and audio formats
• Cut out parts of video/audio losslessly (to cut out commercials, etc.)
• Lossless merging/concatenation of arbitrary files (with identical codec parameters, e.g. from the same camera)
• Lossless Stream Editing: Combine arbitrary tracks from multiple files (e.g. add music or subtitle tracks to a video file)
• Extract all tracks from a file losslessly (extract video, audio, subtitle and other tracks from one file to separate files)
• Remux to any compatible output format
• Take full resolution snapshots from videos in JPEG/PNG format
• Manual entry of cutting point times
• Use one timecode offset per file (and automatically load timecode from file)
• Change metadata for rotation/orientation in videos
• See technical data on all currents
• Timeline zoom and frame/keyframe skipping for precise cutting around keyframes
• Saves per project cut segments to project file
• Show ffmpeg recent command log so you can modify and rerun recent commands on the command line
• Undo redo
• Give labels to cut segments
• View segment details, export/import cut segments as CSV
• Import segments from: MP4/MKV chapters, text file, YouTube, CSV, CUE, XML (DaVinci, Final Cut Pro)
• Video thumbnails and audio waveform
• Edit movie metadata and per-stream metadata
• Cut with chapter marks

Examples of lossless use

• Cut commercials from a recorded TV program
• Remove audio tracks from a file
• Extract music tracks from a video and cut it to your needs
• Add music to a video (or replace existing soundtracks)
• Combine audio and video tracks from separate recordings
• Include a subtitle in a video
• Quickly convert an H264 MKV video to MOV or MP4 for playback on iPhone
• Import a list of cut times from other tools as an EDL (edit decision list, CSV) and run these cuts with LosslessCut
• Quickly cut a file by MP4/MKV chapters
• Change the language of a file’s audio/subtitle track
• Change the author, title, GPS location, recording time of a video
• Export a list of cut times as a CSV EDL and process these in another tool
  • Without having to code again. You can also change the format from TS to MP4 at the same time.
• 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.
• Loop a video/audio clip X times quickly without transcoding

Re-encode only the audio track, leaving the video track

First, export each track as individual files. Then use Handbrake or similar to transcode the audio file. Then use Tools->Merge in LosslessCut to merge the original video stream with the handbrake output (or drag it into the original LosslessCut video to include it as a new track.)

Advanced multi-step workflows

Tips: you can use LosslessCut in multiple passes to achieve separate trimming of individual tracks:

• Open a file and export all tracks
• Open the exported track files independently and cut them as desired
• Add the track back to the video and combine them into one output video

Supported formats:

Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported. The following formats/codecs should generally work: MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9 For more information on supported formats/codecs, see https://www.chromium. org/audio-video.

Typical flow:

• Drag and drop a video file into the player to load or use ⌘/CTRL+O.
• Press SPACEBAR to play/pause
• Select the start and end time for cuts
• Press the scissors button to export the slice
• Press the camera button to take a snapshot

The original video files will not be changed. Instead, it creates a lossless export in the same directory as the original file with from/to timestamps. Note that the cut is currently not precise around the cut points, so video before/after the nearest keyframe will be lost. EXIF data is preserved.

Keyboard Shortcuts:

• SPACE, k Play/Pause
• j Slow down the video
• l Speed ​​up your video
• ← Search backward 1 sec
• → Search forward 1 sec
• . (period) Tiny searches ahead
• (comma) Small backward search
• i Mark in / cut starting point
• o Mark out / cut end point
• e Export selection (in the same directory as the video)
• c Take a snapshot (in the same conductor as the video)
