Split-Screen Previews
Click the Split-Screen  View button   in the Video Preview window to turn split-screen previews on or  off.
Split-screen previews allow you to split the Video Preview window so  you can see your affected and 
unaffected video or your video and the contents  of the clipboard at the same time. Use split-screen 
previews to fine-tune  video effects or to match colors for color correction.
You can use split-screen previews to help match colors between  clips. When the split-screen preview 
mode is set to Clipboard,   the Video Preview and Video Scopes windows  will display the frame you 
copied to the clipboard and the current frame. For more information, see "Monitoring Video with 
Scopes" on page 481.
The Video Preview window temporarily enters split-screen preview mode when  you perform one of the 
following edits:event slip, event slip-trim, event slide, or crossfade/transition slide.  This temporary 
split-screen mode allows you to see the event's first and  last frame as you trim. You can toggle this 
preview mode by selecting   or deselecting the Video  Event Edge Frames command on the View menu. 
For more information, see "Adjusting an Event's Length" on page 158 and "Slipping and Sliding Events"
