There are a couple of ways.

The simplest is to right-click on the clip/event on the timeline and select Group/Clear. Then you'll be able to select and delete the audio only or video only.

If I want all video gone, I just delete the video track.

Faster than right-clicking, you can just click on the video, press "U" (to ungroup) and then press "Delete" to remove the video.
