How to crop a strip (width x height) in Blender VSE?

Question

I have a several videos in a Blender project with dimension larger than 1280x720, which is my output dimension. Instead of rescaling my videos to fit the output dimension, I would like to crop them to 1280x720 pixels, so that part of the scene is discarded. This way, the remaining region would not seem distorted.

How can I achieve this?

Solution

In the VSE select the strip and show the properties sidebar N. There you will find a panel for Strip Input that has the crop settings.
