Each shot chains from the last frame of the previous one; the seam frame and its 1/24s of audio are trimmed automatically.\n\nframes_per_shot sits on H3's 17k+5 grid (243 = ~10s, 362 = trained max ~15s). The loader takes .safetensors or .gguf. Master saves to output/video/H3MULTI/."

        "## Long-form multishot (memory)\n\nFor 2-5 minute videos (12-30 shots), where stock chaining drifts.\n\n**Stock chaining** shows each shot ONE image: the previous shot's last frame. Every hop can only see one hop back, so identity drifts and the error compounds.\n\n**This node splits the two jobs:**\n\n- **keyframe** - what the video continues from (always the most recent frame, so seams stay smooth)\n- **memory** - what the encoder *looks at*: a persistent **anchor** from the start of the piece + the last N shot-end frames\n\nThe anchor never changes, so drift cannot compound.\n\n### Knobs\n- `anchor_frames` **1** = identity anchor on (the fix for long chains). 0 = off.\n- `memory_frames` **2** = how many recent frames the encoder also sees. 0 = stock behaviour.\n\n### Notes\n- Connect a `LoadImage` to `start_image` for I2V; it also becomes the anchor.\n- Render at native resolution (960x544) and upscale after. Native 1920x1088 scored *worse* in blind review and cost ~4x the time.\n- More memory frames = more vision encoding per shot (slower). Test 1 vs 2 vs 4 before committing to a long run."
