Choosing Video Scope Accuracy
You can choose three levels of analysis accuracy from the RT pop-up menu in the Timeline:
Â All Lines: Every pixel of every video line is analyzed, and pixel values are displayed in
the Video Scopes tab. The word “all” appears in the lower-right corner of the Video
Â All Lines Except Top & Bottom: Displays every line except the top nine and bottom
nine lines, which are reserved for signals such as closed captioning. The word “most”
appears in the lower-right corner of the Video Scopes tab.
Â Limited Lines (Fastest): This mode is always used during real-time playback. Accuracy is
limited to 32 lines that are evenly distributed from the top to the bottom of the action
safe area of standard definition video. This is sufficient to catch video elements whose
height equals 5 to 10 percent of the total size of your image.
The accuracy level you choose here affects video scopes when the
playhead is paused or scrubbing; real-time video scope updating always uses the
Limited Lines (Fastest) option.
The lower-right corner of the Video Scopes tab indicates the scope display option
selected in the RT pop-up menu.
