Using Video Scopes in Real Time
Depending on the format of your video and the processing capabilities of your
computer, the Video Scopes tab can update in real time using the same level of quality
available in previous versions of Final Cut Pro.
To enable real-time updating in the Video Scopes tab:
1
Open a sequence in the Timeline.
2
In the Timeline, choose Video Scopes Playback from the RT pop-up menu, so there is a
checkmark next to it.
Note: Using the Video Scopes Playback option requires additional processing power.
Enabling this option could result in a red render bar in the Timeline. Also, the Video
Scopes tab may not update in real time with some formats. For example, playing back
an HDV multiclip requires significant processing power, so the Video Scopes tab may
not update in real time in this situation.
Choosing Video Scope Accuracy
You can choose three levels of analysis accuracy from the RT pop-up menu in the Timeline:
 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
Scopes tab.
 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.
 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.
Important:
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.
