切章标记Deleting parts of a video doesn’t necessarily require professional tools. There are many simple video cutters or trimmers that can perform this task efficiently, and LosslessCut is one of them. LosslessCut aims to be the ultimate cross-platform FFmpeg GUI for extremely fast and lossless manipulation of video, audio, subtitles and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is a great way to save space by rough-cutting large video files acquired from cameras, GoPros, drones, and more. It allows you to quickly extract video from your notebook and discard a lot of useless data without the slow re-encoding that degrades quality. Alternatively, you can add a music or subtitle track to the video without encoding. Everything is super fast as it performs an almost straight forward copy of the data and the awesome FFmpeg does all the heavy lifting.
Open source free lossless editing tool LosslessCut Chinese version LosslessCut features lossless segmentation of most video and audio formats lossless cut part of video/audio (for cutting advertisements, etc.)
Losslessly rearrange the order of video/audio clips Losslessly merge/concatenate arbitrary files (with the same codec parameters, e.g. from the same camera)
Lossless stream editing: Merge arbitrary tracks from multiple files (for example, add music or subtitle tracks to a video file)
Lossless extraction of all tracks in a file (extracts video, audio, subtitles and other tracks from one file into separate files)
Remix to any compatible output format Take full-resolution snapshots from video in JPEG/PNG format Manually enter cutpoint times Apply per-file timecode offsets (and automatically load timecode from files)
Change rotation/orientation metadata in video View technical data about all streams Timeline scaling and frame/keyframe skipping for precise keyframe cutting , so you can modify and rerun recent commands on the command line, undo redo, slice labels, view segment details, export/import sliced ​​segments in CSV format, and import segments from: MP4/MKV chapters, text files, YouTube, CSV, CUE, XML (DaVinci, Final Cut Pro)
Video Thumbnails and Audio Waveforms Editing File Metadata and Chapter Tagging by Streaming Metadata Cross-platform video cutter that relies on FFmpeg function to cut part of the input clip. So you will be prompted to choose the location of the ffmpeg executable when you first launch the application.
Once this is done, you can start loading the video in LosslessCut by dragging and dropping or manually selecting its location. Unfortunately, the input selection window doesn’t filter files to show only compatible files, so you’ll just have to find the files yourself. Also, the output will be saved in the same location without prompting you to choose a filename, so make sure to isolate the file you want to cut in a separate folder for easy finding.
It’s easy to cut out unwanted parts of the video and take frame snapshots to set the start and end positions, and both positions are marked on the playback progress bar. If you press the scissors symbol, the selection will be exported immediately and saved in MP4 format in the same location as the main video. Do this ASAP, unfortunately you can’t choose a different output format or keep the original.
In addition to cutting parts of a video, LosslessCut also lets you capture a snapshot of a video while it’s playing. The output picture will be saved as a JPG file, and there is also no option to change this format. Also, none of the app’s functions can be associated with hotkeys, so you only need to use your mouse to control LosslessCut.
LosslessCut, a fast video trimmer and frame capture tool, does its job as promised, allowing you to remove unwanted parts of your video such as intros, trailers, commercials or end credits. Since it uses FFmpeg to process video without having to perform encoding or decoding, its speed is impeccable. Still, there’s a lot of work to do to make it the go-to app of its kind.

依赖 FFmpeg 的跨平台视频剪辑器
LosslessCut 不需要设置,但是如果没有 FFmpeg,它就无法工作,因为它依赖于流行的视频处理框架的功能来剪切输入剪辑的一部分。因此,系统会在首次启动该应用程序时提示您选择ffmpeg可执行文件的位置。

完成此操作后,您可以通过拖放或手动选择其位置来开始在 LosslessCut 中加载视频。不幸的是,输入选择窗口不会过滤文件以仅显示兼容文件,因此您只需要自己查找文件即可。此外,输出将保存在相同的位置,而不会提示您选择文件名,因此请确保将要剪切的文件隔离在一个单独的文件夹中,以便于查找。

剪切不需要的视频部分并拍摄帧快照
设置开始和结束位置很容易,并且两个位置都标记在播放进度条上。如果按剪刀符号,所选内容将立即导出,并以MP4格式保存在与主视频相同的位置。尽快完成此操作,很遗憾,您无法选择其他输出格式或保留原始格式。

除了剪切视频的某些部分外,LosslessCut 还使您可以在播放视频时捕获其快照。输出图片将另存为 JPG 文件,并且也没有更改此格式的选项。此外,该应用程序的任何功能都不能与热键相关联,因此您只需要使用鼠标来控制 LosslessCut。

快速的视频修剪器和帧捕获工具
LosslessCut 会按承诺完成其工作,使您可以删除不需要的视频部分,例如简介,预告片,广告或片尾。由于它使用 FFmpeg 处理视频,而无需执行编码或解码,因此其速度是无可挑剔的。尽管如此,要使其成为同类应用中的首选应用程序,仍有许多工作要做。
