One single continuous locked shot, no scene cuts. A cheerful waitress in a mint-green 1950s diner uniform with a white apron and a small paper cap stands behind the counter facing camera; a slice of cherry pie on a white plate sits on the counter in front of her.\nTimed beats:\n0.0-0.6s: she wipes her hands on her apron, glancing down at the pie.\n0.6-1.4s: she slides the plate forward across the counter with a soft ceramic clink and looks up at camera with a warm smile.\n1.4-3.6s: (S1) says: <d>[English] Fresh out of the oven, sugar — careful, that plate's hot.</d> Her lips sync naturally to the line; she raises her eyebrows playfully on the word hot.\n3.6-5.1s: she rests both hands on the counter, tilts her head, smiling, steam rising gently from the pie.\nCamera: completely static and locked-off — no pan, no tilt, no zoom, no drift. Medium shot at counter height.\nAudio: at 0.0s quiet diner room tone with a faint refrigerator hum and distant clink of dishes; soft apron fabric rustle 0.0-0.6s; a ceramic plate slide and clink at 0.6s; her clear warm female voice speaking at 1.4-3.6s; a soft single counter-bell ding at 4.3s; room tone continues to the end. No music.\nNegative: no on-screen text, no captions, no watermark, no scene cuts, no camera motion, no morphing hands, no extra fingers, no second person, no music.",

Verified with a same-seed A/B against the 20-step baseline: same choreography, healthy audio (peak ≈ −9 dB, zero clipping).\n\n**The recipe**\n- Turbo v4 LoRA at strength **1.0** via the built-in *LoraLoaderModelOnly* — this graph is 100% core ComfyUI nodes, no custom node packs\n- **8 steps · euler · beta** — no sigma-shift node needed; core defaults carry the dual video/audio clock at this step count\n- CFG-free (BasicGuider): there is no negative-prompt input — write a `Negative:` line inside the prompt itself (see the demo prompt)\n- **1344×768 @ 24 fps**. `length` is frames on a 17k+5 grid: **124 ≈ 5 s**, 243 ≈ 10 s, 362 ≈ 15 s (model max)\n- Seed is **fixed** so your first run reproduces the demo clip; set it to *randomize* for new takes\n\n**Tested / not tested**\n- Verified on 5-second clips at 1344×768. Higher res (1920×1088) and longer clips are untested with this LoRA — earlier turbo versions fell apart there, so treat that as experimental\n- First run: watch the console — you should see **zero** \"lora key not loaded\" warnings on the pruned int8 checkpoint\n- Few-step audio blowout is the classic turbo failure mode; this v4 @ 8 steps is the combo that passed. If you drop steps further, check your audio peaks\n\n**Prompt pattern that works**\nStyle contract → timed beats (`0.0-0.6s: ...`) → camera lock line → an audio timeline starting with room tone at 0.0s → `Negative:` line. Dialogue inside `<d>[English] ... </d>` is spoken verbatim with lip-sync. Give the first spoken line ≥1.2 s of lead-in and anchor t=0 with room tone.\n\n*LoRA: larryvrh's MiniMax-H3-Turbo-Lora (v4_step600 EMA), ComfyUI convert by drbaph.
