Here's how to take advantage of all the tracking tools options in After Effects.
By default, the planar tracker will look at only the luminance data of the image as ... common shots with good contrast, and saves processing time versus full RGB ...
In video, luma represents the brightness in an image (the "black-and-white" or ...
for Needs of Dynamic Luminance Shaping in Object
Experiment 1 showed that, both in the case of Arabic digits and dot arrays
regardless of the difficult situation (low luminance and cluttered backgrounds).
Almost all trackers are now biased to a luminance of black and white
have become more sensitive and are able to read even the RGB light components.
With a track matte, you create a top layer that provides the alpha, or luminance, and a
The RGB colour space has luminance or brightness information embedded.
