Track Removal
Objective :
To Remove the tracks in the background.
Techniques used :
2D Tracking.
Roto.
Premult.
un premult.
Tool Used :
Nuke
Challenges :
To track the markers in proximity to the person, the objective is to follow and analyze the movement of these markers for the purpose of alignment or any other relevant adjustments.
Original
To commence, I employed a time clip, truncating the clip to a duration of 100 frames. Following this, I utilized a 2D tracker to meticulously track the movement of all the markers in the footage.
Subsequently, I employed a roto node for each of the markers and linked their values to the previously established tracker. The shapes created by the roto nodes were then utilized for precise roto-painting adjustments in the footage.
Following that, I applied the "invert" and "premult" operations to eliminate the markers, resulting in a blanked-out area in that specific region of the footage.
After the premultiplication process, I incorporated a blur node to soften and eliminate the sharp edges in the corner areas. In Nuke, the "Premult" operation is employed to manage transparency during the compositing of images or footage.
In the last step, I applied the "Unpremult" operation to eliminate the track markers. In Nuke, "Unpremult" is utilized to reverse the process of premultiplying color values by their corresponding alpha channel, restoring the original color information.
