without re-encoding the frames adjacent to a cut for the codecs using interframe Motion compensation. This limitation is by design to allow the cutting to be lossless, i.e. Typically, the segment start will be "rounded to the nearest previous keyframe", thus the author emphasizes that the program is not meant for exact cutting.

Core functions Įssential functions of the software are: The FFmpeg framework needs to be present on the computer already. With a size short of 100 MB, the software is small and portable, thus it can be started from an external storage medium without prior installation. This is being visualised when operating the program. Ĭompletely lossless copying is achieved when the source file is cut at the reference frames of a group of pictures only. By copying the selected image sequences without transcoding or re-rendering, it achieves very fast creation of the target file in comparison to tools that re-encode frames. The software focuses on the lossless editing of the video files. Thereby it supports all formats supported by FFmpeg.

īasically, LosslessCut is a graphical user interface, in particular useable under MacOS, Windows and Linux, for the Multimedia Framework FFmpeg. Overall, LosslessCut is an excellent tool for anyone looking to perform lossless operations on their video and audio files quickly and efficiently.LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. You can also edit file metadata and per-stream metadata and cut with chapter marks. LosslessCut allows you to import segments from various sources, such as MP4/MKV chapters, text files, YouTube, CSV, CUE, and XML (DaVinci, Final Cut Pro). You can give labels to cut segments, view segment details, and export/import cut segments as CSV. Other features include the ability to save per-project cut segments to a project file, view FFmpeg last command log, and undo/redo. It also includes timeline zoom and frame/keyframe jumping for accurate cutting around keyframes. You can apply a per-file timecode offset, change rotation/orientation metadata in videos, and view technical data about all streams.
#Losslesscut audio sync manual#
LosslessCut lets you take full-resolution snapshots from videos in JPEG/PNG format and provides manual input of cutpoint times. You can also extract all tracks from a file and remux them into any compatible output format. LosslessCut offers a wide range of features, including lossless cutting of most video and audio formats, lossless rearrangement of the order of video/audio segments, lossless merge/concatenation of arbitrary files with identical codec parameters, and lossless stream editing, allowing you to combine arbitrary tracks from multiple files. This is accomplished by an almost direct data copy using the powerful FFmpeg technology, which performs all the grunt work behind the scenes.Īs a result, all of the operations you perform with LosslessCut are exceptionally fast and efficient. With LosslessCut, you can also add music or subtitle tracks to your video without needing to encode the entire file. This allows you to extract the desired parts of your videos quickly without losing quality or having to perform a slow re-encode process. Its primary feature is lossless trimming and cutting of video and audio files, which is particularly useful for reducing the size of large video files captured from devices like GoPro, drones, or video cameras.
