Whenever I changed the playback speed for clips it slows down the video only and leaves the audio the same. Is there anyway to slow down the audio as well so that it matches the video?
How would I group them? Because I thought they were already grouped just from default. Ignore Event Grouping isn't selected and the audio and video both move when I drag one or the other so doesn't that mean they are grouped?
It should be grouped automatically, yes. I just tried on my VMS, and when I resize a clip that I drop in the timeline, it resizes both the video and audio, and the audio plays faster/slower depending on the kind of resize.
To group two elements: SHFT+click on the specific video and audio scene and the press "G". That should group them. Then, resize your video by clicking CONTRL+DRAGMOUSE (not simply drag-mouse).
