Honest runway with <code>hop_refine: full</code>: Holds clean for ~5–6 continuous clips on Turbo and ~7–8 clips on non-Turbo before texture changes become visible.

Gentle pool water lapping."</li><li>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").</li><li>Don't re-describe the face on Shots 2+: Describe only the new action; the reference rail and join pin carry her look.</li><li>No ellipses (<code>...</code>) inside dialogue: Connect clauses inside speech with a simple comma (<code>,</code>) so the audio branch never fills pause gaps with gibberish.</li><li>Set the final shot's <code>tail</code> to <code>settle</code> or <code>hold</code>: So the film lands cleanly instead of starting a new gesture on the last frame.</li></ol>

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

Bug fixes and some minor changes - HTC 3.1.1▎ - hand_tie music videos: lock a song with master_audio_file; lip sync holds across every join.▎ - HTC Save Video: a long-form save with built-in RTX frame-gen x2, now in the Starter.▎ - STANDARD tab: writes single-generation H3 prompts (T2VA / Ref2VA).▎ - Upsample: back on the original MMH3 recipe; the upsample LoRA is retired.▎ - Starter: uses the official ref2va DiT on euler/simple. Add a turbo LoRA or raise the steps.▎ - Fixes: hand_tie joins (people standing up, props jumping, silent quoted lines) and 15 s hops.
