- Creates realistic light streams, ideal for fixing inadequate lighting or adding artistic flair.
- Setting Up Relight Nodes [6:15]
- Node Structure [6:18]: Add two new nodes after your primary color correction: one for "map" and one for "relight." [Image 15]
- Applying the Effect [6:28]: Drag the "Relight" effect from the "FX Library" to both the "map" and "relight" nodes.
- Connecting Nodes [6:39]
- Right-click to remove the link between the "map" and "relight" nodes.
- Connect the output of your "primary" color correction node to the first input (input 1) of the "relight" node.
- Connect the output of the "map" node to the second input (input 2) of the "relight" node.
- On the "map" node, check "Output Surface Map" (サーフェスマップを出力).
- On the "relight" node, change "Use Internal Map" (内部マップを使用) to "Use Input 2" (入力2を使用).
- How Relight Works (Analogy) [7:09]
- Think of the "relight" node as the "light source person" and the "map" node as the "mapping person." [Image 16]
- The "light source person" applies light but doesn't understand the space.
- The "mapping person" recognizes the 3D space, including object placement, depth, and angles, which is crucial for realistic shadows and highlights.
- By feeding the original footage to "input 1" and the spatial information from the "mapping person" to "input 2," the "light source person" knows where and how to apply light effectively.
- Lighting Control Options [7:59]
- Adjusting Light Characteristics [8:34]
- Turn off "Relight Map Preview" (リライトのマップをプレビュー) for real-time visualization.
- Adjust properties like "Brightness," "Falloff," "Contrast," "Glossiness," and "Shadow Softness" (シャドウソフトネス) to fine-tune the lighting effect. [Image 17]
- Before/After [9:21]: The tool can recreate subtle shadows and highlights with remarkable realism due to its spatial awareness.
2. AI Ultra NR [9:45] [Image 18]
AI Ultra NR (Noise Reduction) is an advanced tool for cleaning up footage by removing both chroma (color) noise and luma (brightness/luminance) noise. It intelligently cleans noise without sacrificing important image details or making the subject appear overly smooth.
- Understanding Noise Reduction [9:51]
- How to Use AI Ultra NR [10:04]
- Adding Noise Reduction [10:05]: Add a "Noise Reduction" effect from the "FX Library" to a new node. [Image 19]
