Maybe I can’t use the crop filter properly but it seems that it doesn’t do anything. I have a footage whose real content is smaller than the footage’s dimensions. I want to get rid of edges. So I crop. And I export. The exported file still has the edges. If the footage has dimensions like 1920x1200 px and the real content is like 1920x1080 px then I want to get rid of the unnecessary edge so that the final video has the dimensions 1920x1080 px having only the real content and no edge. How to do that?

You have posted to a documentation post. You might want to start a new Help post on what you want to accomplish.

There is no need for a crop, it will automatically cut the edges, just adjust the position.

Crop doesn’t show because it is already outside of the viewport, you have crop even more to see it affecting the edges.

Or

Before Editing change the project dimension to 1920x1080 instead of automatic.
