A little tip for Split Edits

If you have a clip sitting on top another clip (connected clip) but you'd like to drag it into the primary story line but not disrupt the audio of the clip you will be covering. Select the position tool, and turn on "Expand Audio/Video clips -> For All, then drag the clip down into the primary storyline.

You will notice that only the video of the primary storyline is replaced while the audio simply moves out of the way. Creating a "Split Edit or an L Cut".

This also works when dragging in clips from the browser using the position tool.

I do this differently. Just select the connected clip and hit ALT-CMD-DOWNARROW and the connected clip will slide down into the primary storyline while preserving the former clip's audio. I use it all the time!
