Color correction: video scopes in FCP

You bringing up the video scopes by going to Tools > Video Scopes. Alternatively, choose Window > Arrange > Color Correction, to change the whole Final Cut Pro layout in color correction mode. The video scopes are:
  • the Waveform Monitor
  • the Vectorscope
  • the Parade scope
  • the Histogram

The waveform monitor

Selet this by going to the Video Scope toolbar and choosing Waveform. The waveform monitor shows:
  • the relative levels of brightness and saturation in your footage
  • it reads from left to right, just like the levels from left to right in your clip
  • 0% at the bottom is absolute black
  • 100% at the top is white
  • over 100% white is not safe for television playback

The vectorscope

Selet this by going to the Video Scope toolbar and choosing Vectorscope. It is layed out like the standard color correction wheel, only without the colors. It shows:
  • the distribution of color in your clip on this scale
  • the squares are called targets and represent the colors
  • the distance from the center of the circle indicates saturation of the color
  • a color that shoots past its target is too saturated for television
  • with the 3-way color correction filter and the broadcast safe filter color saturation can be brought back within television boundaries
  • there is a flesh tone line on the vectorscope that is a good indication for accurate skin tones

The histogram

Selet this by going to the Video Scope toolbar and choosing Vectorscope. This tool shows:
  • the relative strength of the luminance values in your clip
  • 0 on the left is black
  • 110 on the right is ”super white”
  • luminance is the measure of black and white or non-color information
  • the height of your peaks and valleys indicate the number of pixels in your image at that percentage of luminance
  • the histogram is a great tool to check exposure levels between images & to compare contrast between clips.
  • a low contrast image will have a big clump in the middle of the graph
  • a high contrast image will be spread out across the histogram.

The parade scope

This scope is a modified version of the waveform monitor.
  • Instead of showing us the overall saturation, it splits up the red, green, and blue parts of the image and shows them to us side by side.
