 **Originally inspired by:** [mikkel/ComfyUI-text-overlay](https://github.com/mikkel/ComfyUI-text-overlay)
 
-This node extends and refines the classic ComfyUI Text Overlay concept with a **re-engineered rendering engine**, **precise alignment logic**, **new customization parameters**, and **enhanced batch handling** — making it the most advanced text overlay solution available for ComfyUI.
+This module provides the **most feature‑rich and precise text overlay system available for ComfyUI**, including:
+
+* Completely re‑engineered layout engine
+* Pixel‑perfect multiline stroke alignment
+* Opacity‑aware backgrounds and shadows
+* Letter/line spacing, padding, and alignment controls
+* Full animation engine (fade + directional movement)
+* Batch-aware rendering with smart caching
+* Full video processing node with audio‑preserving re‑mux

-| ---------------------------- | ------- | ----------------------------------------------------------- |
-| **animate**                  | Boolean | Enable or disable animation.                                |
-| **animation_kind**           | Enum    | Selects animation type (`fade_in`, `move_from_left`, etc.). |
-| **animation_frames**         | Integer | Number of frames to complete the animation.                 |

+* Automatically caches layout on first frame
+* Maintains perfect consistency across all frames
+* For animated batches: animates through first *N* frames, then holds the final pose
 
-Behavior:
+### ✔️ 6. Full Video Support
 
-* For single images, the node outputs either one static frame or an animated sequence.
+The **Advanced Text Overlay – Video** node:
 
-* For batches/videos, animation applies over the first animation_frames frames, then holds the final pose.
-
-Technical Summary:
-
-The animation module provides:
-
-* progress(t, T_minus1, ease): easing interpolation over frames.
-
-* compute_opacity(kind, p, target): calculates alpha fade transitions.
-
-* compute_offsets(kind, p, img_w, img_h): determines X/Y displacement for move animations.
-
-These functions are integrated directly into the node’s rendering loop for seamless animated overlays
-
-### ⚙️ 6. Batch and Workflow Enhancements
-
-* Native **batch support** — automatically applies consistent overlay logic across all input images.
-* Optimized performance and memory use when processing large image sets.
-* Node parameters persist and preview correctly in ComfyUI sessions.
-
-### 🧩 7. Developer & Extensibility Features
-
-* Modularized code for easier maintenance and feature additions.
-* Clean separation between text layout and rendering logic.
-* Ready for further extensions such as shadow layers, gradient text, or dynamic variable injection.
+* Reads a video frame‑by‑frame
+* Applies the same overlay logic
+* Writes a new MP4
+* **Automatically re‑injects the original audio track with ffmpeg**
+* Optional `delete_original` flag
