ENDA Episode 125→ The time when ENDA shares the importance of understanding how your comp works (Part 2)

Last time, we established that knowing “how” to wire up nodes isn’t enough; you need to grasp why each operation exists. Today, let’s dive into a practical workflow for dissecting a troublesome script and rebuilding it from the ground up:

1️⃣ Identify the Culprit

Solo your plate:

Disable all CG, mattes, and overlays, leave only your raw plate. This immediately shows you whether the base shot has issues (motion blur, edge fringing, noise) that your comp must solve.

Progressive reveal:

Re-enable one major branch at a time (keying→tracking→color→effects). Watch which breaks the illusion. That branch is your hotspot.

2️⃣ Replay with Variations

Toggle parameters:

For each suspect node, scrub through its key parameters (e.g. keyer thresholds, blur radius). Observe how small tweaks ripple through the comp.

Swap in a neutral plate:

Replace your plate with a simple test pattern (gray or checker). Does the node still break? If so, its issue is logic-based, not plate-based.

This way, you will be able to understand what those node parameters are actually doing to the pixels in the shot. Once you understand how it works, you could start to rebuild it… But that would be for another episode.

The journey continues…
