Open your audio/video QuickTime file and then open the the Movie Properties window.
Highlight (single click) on the "Video" track and "Extract" (upper left of that window) to make a new video only version.
Open your audio QuickTime file, select all (Command-A) and copy (Command-C). This stores your audio track on the Clipboard.
Switch back to your "extracted" video track, select all (Command-A) and choose "Add to Selection & Scale" (Edit menu).
Test this file and then "Save As" to make a self contained QuickTime .mov file from these parts.
