Nuke Essentials : A Beginner's Guide to VFX Compositing

Master the core node types in nuke, merge, transform, blur, grid, roto, grade, and constant, as essential building blocks to assemble, color-correct, and mask your compositions within a node tree.

Nuke uses a node-based workflow that connects nodes in a flow for flexible, non-linear VFX compositing with easy backtracking, versus layer-based systems.

Learn to connect and organize nodes in Nuke for cleaner, faster workflows. Understand node order, backdrop nodes, and dot nodes to manage complex composites.

Rotoscoping in VFX teaches you to cut out objects or people from footage with a mask, enabling seamless compositing with CG elements; it's a vital, practice-driven skill.

Apply rotoscoping to real footage using a roto node and a B-spline, refining alpha with premultiply and key mix, then frame-skipping animation and edge blending for seamless composites.

Analyze the shot to map movements, plan with multiple small shapes near joints, and use tracking, renaming, edge detection, and color overlays for a clean, accurate roto.

Explore the basics of 2D tracking in nuke to attach motion data to graphics or text, enabling seamless composites with live-action footage.

Learn to apply tracking data to a text using a tracker node, refine points with the curve editor, and transfer motion to text via match move and a merge setup.

Master stabilization and matchmove using one-, two-, and four-point tracking to capture translation, rotation, scale, and perspective. Enable rotoscoping, screen replacement, and corner-pin composites.

Learn a practical 2d tracking workflow to integrate tracked elements with footage, including denoising, stabilizing, matchmove, roto, edge blur, color matching, and reintroducing grains for realistic composites.

Master green screen and chroma key to remove the bright green backdrop and replace it with any background. Use foreground elements like actors in fantasy worlds or futuristic settings.

Refine green screen keys by removing spill and edge cleanup artifacts with basic dispel techniques, color smear, and simple gizmos to blend the subject naturally with the background.

Generate soft and core mattes to create a clean alpha for green screen removal, then refine edges with erode, blur, and garbage roto while preserving hair details.

Capture a clean plate as a blank background to remove unwanted objects, or clone or paint the background to fill gaps, ensuring a clean, professional final composite.

Learn to remove unwanted elements with roto paint and sequence painting, create a clean plate using frame hold and background reference frames, and apply tracking to blend across frames.

Remove tracking markers using the roto paint tool and the transform node, employing clone strokes, opacity and gamma tweaks, bezier masks, and the chemex node with A and B inputs.

Explore the two key color nodes in nuke—grade and color correct—using absolute black and white points, lift, gain, offset, and gamma to shape shadows, midtones, and highlights.

Color correct raw footage by denoising, setting black and white points, adjusting midtones, and applying a grade and color correct node, then reintroduce grain for the final look.

Apply premultiply to the color channels by the alpha, then unpremultiply before color grading to keep edges clean and avoid artifacts in compositing with transparent edges.
