Split, cut, edition, save, how?

I assume that when you say “save” you actually mean “export”. “Save” in Shotcut refers to the project file itself and not the rendering of your project as a video file.

An alternative workflow to what @Elusien suggested for exporting separately edited parts in one timeline:

  • Place your video file on one video track.
  • Split into the four parts.
  • Space out each of the four parts a bit from each other to separate them.
  • Start editing each of the four parts separately. If one part needs to have a longer duration then turn on the ripple button to move the other parts down the timeline. Here’s a demo of what I mean.
  • When you are done with all your editing, create a range marker for each of the four parts and select them one by one in the Export menu to render them out separately from each other. More info on Markers and Ranges here:
