resize video

[Mattspace]

The videos I am currently working with are all different different sizes, meaning when I insert them into premiere they can be either zoomed in or zoomed out. Is there any way I can set them or the video to the same size? I have heard some bring up resizing, but IDK if that is what I want.

Right click on clip in timeline: Set to framesize.

Same option is to be found in the Preferences > Media > Default Media Scaling.

If Preferences is set it does not work on already imported media, but works for media imported after the fact.
