# 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.
