LightWorks is a cross-platform, open-source application to edit videos, although only the basic version is available for free (which can only export video in "YouTube" format and requires re-validation regularly.)
Using Lightworks 12.6, here's how to import a video, extract some parts, and save the output:
Simply launch LW. In the Projects Browser window that is displayed, in the "Create a new project" section, enter a name and leave the Frame Rate to "Auto" to use the frame rate from the video you will import next.
! Make sure the video uses a constant rate; If not, re-encode both video and audio: ffmpeg -i input.mp4 -pix_fmt yuv420p -c:v libx264 -crf 18 -r 25 -c:a aac -b:a 128k -preset slow output.mp4
A Bin is a list of videos and edits. Here is one way to import videos into a Bin:
Alternatively, you can create a new Bin by clicking on the grid-looking icon "Create a new bin"
There are two different views to display the contents of a Bin: Tile or List.
In the project's Bin, simply double-click on a file. The playback controls are either at the bottom of the screen (Global) or within the video's window (On Each Viewer).
To move back and forth, besides the playback controls, there's a set of convenient keyboard shortcuts: j k l (backward, pause, forward).
In the Tools window, click on the Export icon. Note the Free edition can only as the "YouTube" preset.
It makes the computer sluggish on slower hardware.
Open the Bin, select the items, right-click, and select "Remove tagged".
Only Permanent Bins can be searched.
You can tell them apart by the color used to display their name: Blue = Transient, Green = Permanent.
Stereo = two audio channels?
