Video Scopes Accuracy
To create a real-time analysis of the video signal (even during adjustment and
playback), Color downsamples the current image to a resolution of 384 x 192. The
downsampled image is then analyzed, and the resulting data displayed by the
currently selected scopes. This same downsampled resolution is used regardless of
the original resolution of the source media.
Using this method, every pixel contributes to the final analysis of the image. In tests,
the graphs produced by the Color video scopes closely match those produced by
dedicated video scopes, and are extremely useful as an aid to evaluating and
matching shots while you work in Color. However, you should be aware that the
Color analysis is still an approximation of the total data. Dedicated video scopes are
still valuable for critical evaluation.
Note: If you’re concerned about catching stray out-of-gamut pixels while you make
adjustments for QC purposes, you can turn on the Broadcast Safe settings to protect
yourself from QC violations. For more information, see “
