I'm guessing that the older Windows Movie Maker does something like
this.

Editing the same files in both Movie Maker and Openshot was like day and
night. Openshot's preview was clearly nicer looking, so I presume that
Movie Maker cut the quality way down.

Title:
  (Feature) Working with full HD video files is slow, even on modern computers

Status in OpenShot Video Editor:
  New

Bug description:
  (This is a feature request)
When working with high quality source files, the user interface gets slow and hard to use. Previews are slow, sometimes almost unusable and the application may even crash as a result.

A great feature would be if one could convert the source files to some nice light "working format" (lower quality, smaller frame sizes etc), so that timeline editing goes fast and easy, and that one, when it is time for rendering, could choose to use the original files so that the rendered video becomes high quality.
