Josh: this is a fantastic tip, can’t believe I’m only learning this one now 🙂
To make it clearer :
1. drag your VIDEO CLIP(s) up one (or more) tracks (ex. V1 to V3)
2. Don’t let go of your left mouse button (don’t let go of anything basically)
3. Press + hold shift , and move your mouse down towards the audio tracks (which will “push” them down, exactly the way you’d want them to go in the first place)
Thanks again,
Josh (yep another one, from Switzerland)
