The QuickTime_Writer plugin merges channels the same way ImageJ does
when it displays the hyperstack so what you see on the screen is what
you get in the QuickTime movie. Before saving, you can enable/disable
channels using the "Channels" tool (press shift+z to open). Adjust the
contrast  and brightness of the current channel using the B&C tool
(press shift+c to open). Change the color of the current channel by
selecting a different LUT from the Image>Lookup Tables menu. Merge
channels using the Image>Colors>Merge Channels command.

Starting with the 1.42o daily build, the File>Save As>AVI command saves
hyperstacks the same way the QuickTime_Writer plugin does.
