Hand Tie Clips — multi-hop MiniMax H3 video + audio, one queue

Turn 8-second MiniMax H3 clips into 1-minute+ films — same face, same voice, synced dialogue, one-shot retakes, one continuous take with no joins, and 2 MP upscaling — all from one ComfyUI node.

🆕 New in 3.4.0: One Continuous Take (sand_tie)

• A whole run of hops renders as ONE video. No joins to see; a take only cuts where you write anchor: restart.

• 🎬 2:03 one-take music video · 52 s two-person take, street → boardwalk → bench · 65 s walking selfie (upsampled)

• Retake one hop and only that hop is redrawn; the rest of the take is kept.

• tone_lock keeps a long take from drifting brighter (0.5 / 0.75 / full).

• Song-locked takes (master_audio_file) keep lip sync for the whole song.

🎬 What You Can Do

• Simple Mode (Standard MMH3 ref2va / t2va + Realism Boost): Paste standard 6-field MiniMax H3 prompts (passed through verbatim!) or plain prose for single clips (chains = 1) with the visual REFS rail, realism_boost: on (steps = 6 → 2 base + 10 realism LoRA steps) + audio_refine: on (5 steps), and 2 MP upsampling.

• Shots Mode (Multi-Hop Chains): One short beat per card (5 s – 15 s each) with camera, framing, pace and join controls.

• Visual & Voice Reference Rail (REFS): Up to 9 character/location stills and voice clips right on the node, with @tags and per-hop schedules (no Load Image spaghetti).

• Lossless Retake Board (TIMELINE): Every hop is cached. Lock the shots you like, or click ⏵ on Shot 4 to re-roll only Shot 4 while Shots 1–3 load in a second.

• Guided SWAP: One-hop character or head swap driven by a reference video's motion & audio (replace_person, head_swap, face_only, keep_person) with a wardrobe override box and auto-loaded Swap LoRAs.

• Built-In 2 MP Upsampler: Enlarges the finished film with the H3 latent upscaler and a light 3-step Open-H3-Regenerate-2K redraw. Small, distant faces are redrawn as close-ups so they keep their person.

• WRITE (Local AI Writer): Connect LM Studio / llama.cpp to draft shot cards, one-take timelines or music video layouts from a one-sentence brief. STANDARD writes a single checked H3 prompt.

🔗 Three Ways to Join Shots (pin_mech)

• motion_context (Default — Built-In): Native latent-slice + audio relay (credit to NikoDemon80). Honest runway with hop_refine: full: ~5–6 clips on Turbo, ~7–8 on non-Turbo before texture changes show. Plan a cut (anchor: "restart") every 4–5 clips.

• sand_tie (New — One Continuous Take): Each take renders as one video, its hops overlapping windows. Best for long walks, songs and scenes that move through places. Needs a recent ComfyUI (MiniMax H3 context windows) and overlap 0.9 s.

• hand_tie (Experimental): Renders a low-res preview of the take first and ties every hop to it. Pair with qwen3vl_4b_fp8_scaled.safetensors in models/text_encoders/.

💡 The 5 Golden Prompting Rules (H3 runs at CFG 1.0 — every word is additive)

1. Never name what you want to stop: Don't write "She stops talking" — write "She smiles with her lips closed. Gentle pool water lapping."

2. Silence must be written as a room tone: An empty soundtrack invents speech. Always name a narrowband sound ("low hum of the refrigerator", "soft breeze").

3. Don't re-describe the face on Shots 2+: Describe only the new action; the reference rail and join carry her look.

4. Only words inside the quotes: A laugh or sigh written inside a line is said out loud as a word. Write it outside: she laughs, then says, '…'

5. Set the final shot's tail to settle or hold: So the film lands cleanly instead of starting a new gesture on the last frame.

🎞️ One-take tip: in a sand_tie take, every hop opens with the same camera sentence and the action goes on an At mm:ss-mm:ss, timeline. PROMPTING.md has the full rules; WRITE does it for you.
