There are many reasons why you might want to extract clips from videos. You can, for example, use some of your favorite scenes from movies to use as additional material that will spice up your YouTube videos. Using a full video editor would be overkill. Lossless cut can extract clips from video quickly and without quality loss.
LosslessCut is available for macOS, Windows, and Linux. Go to its Github page to download the installer for the platform of your choice.
For Ubuntu, the easiest way to install it is by snap:
Unfortunately, LosslessCut does not appear to be available in the repositories of most of the major Linux distributions. This means that your best alternative is to download it directly. from its official page on GitHub and install it manually.
Import a video
After installation, launch LosslessCut from its location in your Applications menu.
The first step is to import a video that has a section that you want to extract. You can do this by selecting “File -> Open” or by pressing Ctrl + THE on your keyboard.
You can also import your files by dragging and dropping them from your favorite file manager into the program window.
Videos come in many shapes and formats. The file you import may not be one of the formats natively supported by the application. In this case, you might miss the audio or see a poor quality preview. However, this will not affect the final result, which will be identical to the original file.
Note that although LosslessCut supports importing multiple files at once, due to its very nature, they must be encoded the same. This is because the program does not recode its output but extracts the parts that interest you as they are.
Export some clips
Since you don’t want to clone your entire video, but only export certain clips of it, the next step is to define those parts.
You can move forward and backward in your video “on its timeline” by left clicking and dragging the horizontal bar below the video preview. You can also use the left and right arrow keys on your keyboard to move in smaller steps.
Locate the start of the clip you want to export. You can try to fine-tune the position using the left and right arrow keys, but it doesn’t matter much. To extract clips from the original video without having to recode them, LosslessCut automatically selects the keyframe closest to the frame you selected and uses it instead as the start or end of your clip.
To mark the start of your clip, click on the small icon with your finger pointing left, the fourth in the controls section below the timeline.
Do the same for the end of your clip by first locating it using the timeline. Mark it by clicking the button with your finger pointing to the right (fourth from the end in the same controls section).
At the top right, in your list of segments, you will see the duration of the clip you are going to export, in seconds, milliseconds, and frames. If you want to export more clips from the same video source, you can do it in one batch by adding more segments and repeating the previous steps.
When you have defined one or more segments, click on the blue Export button at the bottom right of the window to start the process. It should be mentioned that the process is almost as fast as a file copy because there is no re-encoding involved.
When the process is complete, you will find the ripped clips in the same folder as your original file, with details about the selected time range combined with the name of the original file. You can play them with any media player you would use to play the original file.
If instead of extracting clips from video all you want to do is extract audio from video, this will show you how. You can also reduce the size of the video in iOS.
