ComfyUI pins H3 keyframes to the **first and last frame only**. This\ngraph places as many as you like, anywhere.\n\n**How to use it**\n1. Connect one image per anchor to `image_1 .. image_6`.\n2. Give one position per image in `positions`, same order.\n   * `0` = first frame, `0.5` = halfway, `1` = last frame\n   * a value **above 1** is an absolute frame index (`121`)\n   * `0, 0.5, 1` = start, middle, end\n3. Everything else is a normal H3 render.\n\n### It MOVES or it CUTS - and your images decide which\n\nGive it images with a plausible path between them (same place, different angle\nor framing) and H3 **interpolates**: a real move that arrives on time. Measured\non a 243-frame render with one anchor at frame 121, the closest frame to the\nanchor image was frame **122** - off by one - with no cut anywhere (peak\nframe-to-frame change 2.3x median).\n\nGive it images with **no** possible path (a kitchen and a diner) and H3 **cuts**,\nthen holds. That is not a bug and not a limit of this node: stock first/last\ndoes exactly the same with such a pair. It is the model doing the only sensible\nthing.\n\nBoth behaviours are useful. The second gives you a **timed shot change inside a\nsingle generation** - and because it is one generation, the audio runs unbroken\nstraight through the cut, with no voice re-derivation and no seam.\n\n### Notes\n* `positions` must have exactly one entry per connected image, or it errors.\n* Two anchors cannot land on the same frame.\n* Anchors are sorted for you; wiring order does not matter.\n* Frames follow H3's 17k+5 grid: 243 = ~10.1s, 362 = trained max ~15.1s.\n* **Anchor strength** (the optional node) exposes a core setting nothing else\n  reaches. 1.0 feeds anchors in pristine; lower lets the model drift further\n  from them.
