After Effects
AI-generated post-processing effects applied to video using Claude Sonnet.
Overview
The After Effects node uses Claude Sonnet (configurable via the model selector — any of the shared LLM registry’s models) to interpret a natural language prompt and generate a structured effect plan. The plan specifies post-processing effects such as color grading, vignette, film grain, noise, letterboxing, animated blur, trail, and motion blur. A live preview is available in the config panel before rendering.
Reasoning-capable models additionally show an Effort selector next to the model picker (Auto by default — the vendor default, no charge change). xhigh/max bill one tier up, same rule as every other LLM-backed node — see the Generate Text node’s Reasoning effort section for the exact formula and worked examples.
Advanced mode. Gemini models offer an Advanced mode switch. Turning it on runs the model on the provider’s own API instead of through our aggregator, which is the only place Temperature, Max Tokens and the full reasoning-depth range actually take effect — those controls appear once it is on. It bills one credit tier up, and the node’s cost badge updates immediately so you can see the change before running. On a non-Gemini model the switch is visible but disabled, with the reason shown inline.
Configuration

Duration of the output. Range: 1–300 seconds. |
Inputs & Outputs
Inputs:
in– Source video to apply effects to.
Outputs:
composition– Effect plan (JSON). Connect to a Render Video node for final output.Best Practices
- Describe effects in plain language (e.g., “cinematic color grade with warm tones and subtle vignette”).
- Use the config panel preview to verify the effect plan before rendering.
- Combine multiple effects in a single prompt rather than chaining multiple After Effects nodes.
- Keep the duration aligned with your source video length to avoid blank frames.
Common Use Cases
- Applying cinematic color grading to raw video footage.
- Adding film grain and vignette for a vintage look.
- Creating letterboxed widescreen presentations.
- Applying animated blur or motion-blur effects for stylistic emphasis.
- Adding trail effects to create ghosting or echo visuals.
Tips
- Available effects: color grade, vignette, grain, noise, letterbox, animated-blur, trail, motion-blur.
- Motion blur uses CSS
filter:blur()and trail effects useOffthreadVideoghost layers in Remotion. - The preview in the config panel shows the effect applied to the source video. It appears automatically when a source video is connected.
- The output is a plan that must be rendered through the Render Video node.
