The gamma curve value is cleared for the current frame, and the gamma curve is updated without
affecting its adjustment curve. A keyframe is set with the reset values.
To clear RGB adjustment or luminance curve values for the current frame, click one of the channel
buttons (RGB, Red, Green, or Blue) or the Luminance button to display the curves you want to
affect, then select Clear in the Reset box.
The values for the displayed adjustment curves or luminance curve are reset for the current frame. The
curves' control points are distributed equidistantly along each curve. A keyframe is set with the reset
values.
Matching Colours in Clips
You can match a sample from the result clip to one from a reference clip. Matching clips can improve
continuity between clips. You can:
Match specific colours.
Match shadows, highlights and overall saturation.
Matching Specific Colours
You can match plot samples to reference samples using the trackballs and by aligning the colours in the
vectorscope. For example, you may want to match a red in one image to a different shade of red in another
clip. For information on using Plot and Ref controls, see
Sampling Clips in the Image Window (page 813).
To match specific colours:
1 Select Result from the View box.
The result clip is displayed in the image window.
2 If necessary, position the split bar so that both a reference clip and the result clip appear.
3 Enable Plot and then sample a colour in the clip you want to modify (the result clip).
A red plot line is displayed in the 2D luma histogram indicating the luma value of the sample. In the
2D vectorscope, you can view the saturation and hue of the sample (outlined in red). In the 3D
vectorscope, you can view the sample in terms of HLS.
4 Enable Ref and then sample the colour in the reference image you want to match.
A yellow reference line is displayed in the 2D luma histogram indicating the luma value of the sample.
In the 2D vectorscope, you can view the saturation and hue of the sample (outlined in yellow). In the
3D vectorscope, you can view the sample in terms of HLS.
5 Use the 2D luma histogram in the Basics menu and 2D vectorscope in the image window to determine
which controls you need to use.
When:Drag:
You need to adjust the luma values in the highlights or shadows without
modifying the chroma. Drag the field so that the plot line in the 2D luma his-
togram moves towards the reference line.
White or Black field
You need to adjust the chroma values in the image without modifying the
luma. Drag the trackball(s) so that the plot sample in the 2D vectorscope moves
towards the reference sample.
