+# ETK LTXV Timeline Image Editor
+
+Build an LTXV/LTX 2.x image-guide timeline with composited image and text
+layers, per-keyframe prompts, strengths, and frame positions.
+
+## Inputs
+
+- `width`, `height`: Output image dimensions, rounded to multiples of 32.
+- `length`: Video frame count. LTX-compatible values are one plus a multiple
+  of eight.
+- `timeline_json`: Serialized editor state. The browser editor maintains this
+  value automatically.
+- `fps`: Timeline frame rate used to convert frames to seconds.
+- `images`: Optional connected image batch used to populate keyframes.
+- `prompts`, `strengths`, `times`: Optional aligned lists that replace the
+  corresponding keyframe metadata by index.
+
+## Outputs
+
+- `edited_images`: Composited RGB keyframe images.
+- `unedited_images`: Matching RGBA source images before editor effects.
+- `width`, `height`, `length`: Normalized timeline dimensions.
+- `strengths`: Per-keyframe image-guide strengths.
+- `frame_indexes`: Video-frame positions.
+- `position_seconds`: Positions derived from the frame rate.
+- `prompts`: Per-keyframe positive prompts.
+
+The node performs image editing only. It does not load or execute a model,
+text encoder, CLIP, or VAE.
