MiniMax-H3 Multishot — Seamless Chain: multi-shot scenes that render as one continuous take (picture + audio)

The big one. Everything since v1.4, consolidated - headlined by something no other H3 workflow does: voice identity that survives the chain.A character's voice now holds across every chained shotChained multishot re-performs the voice from text each shot, and it drifts - that has been the known limitation since v1.1. Two new controls on the multishot sampler end it:<ul><li>voice_ref (AUDIO input): feed a voice clip and it anchors EVERY shot as <code>&lt;Audio 1&gt;</code>. Stereo, sample rate, and length are guarded internally - a mono clip no longer crashes the packed layout.</li><li>self_anchor_voice (toggle): no file at all. Shot 1's own rendered voice automatically becomes the reference for every later shot. Write shot 1 so the character speaks a clean solo line, and the scene anchors on itself.</li></ul>Verified A/B - same seed, same start frame, same continuation line: the plain chain drifted off the character's voice; the anchored render held it and matched the source loudness within 1 dB. Requirements: run the chained shots on a ref2va checkpoint (fl2va was not trained with reference rows) and bind the ref in each shot's prompt: <code>Her voice is the voice in &lt;Audio 1&gt;.</code> The AIO workflow ships with a muted VOICE ANCHOR node ready to unmute.VRAM management is now automaticLeave <code>activation_reserve_gb</code> at 0 and the pack sizes the reserve from the actual render shape, measures the true allocator peak of every run, and tightens itself per GPU, model, and shape. The trap where lowering the resolution made renders 5-10x slower (the reserve shrank below the allocator pool and the driver thrashed) is gone. Manual values still pin, and multi-GPU rigs no longer evict a dedicated-GPU text encoder every shot - thanks @VladiCz for measuring that one at a third of his render.LoRA stack, in every workflowA four-slot MODEL-only H3 LoRA Stack sits inert between loader and sampler in every bundled workflow. Empty slots are a true pass-through; pick a LoRA in slot 1 (the turbo distill, a style LoRA) instead of rewiring.New nodes<ul><li>H3 Ref Folder / H3 Auto Refs / H3 Ref Batch - folder-driven reference casting, up to 9 images, with dialogue stripped before name-matching so a merely mentioned character does not cast.</li><li>H3 Cartridge Loader - portable <code>.riftcast</code> character cartridges (anchor frames + references + voice), drop-in auto-install.</li><li>H3 Episode Split / Last Frame / Concat A/V - two-stage episode assembly. The concat matches stage B's sharpness and tone to stage A at the seam, and passes stage A through untouched for single-shot renders.</li><li>H3 Studio Controls (+ Sampler by Name / Sigmas by Name) - one node whose width/height/frames/steps/sampler/scheduler drive an entire multi-stage graph. No more stage A rendered at one size and stage B at another.</li><li>H3 Keyframe Inject (experimental) + the merge patch that lets references and keyframes COMPOSE in one conditioning instead of the refs silently discarding the keyframe.</li></ul>Worth knowingWith the 4-step turbo distill at 10-12 steps, sample with <code>euler</code> + <code>beta</code>. Multistep solvers extrapolate across step history, and H3's audio runs on a different sigma clock than the video - on a distilled model that math over-steps the AUDIO stream and it comes out distorted.GGUF loading stays fully automatic (the v1.4.1 fix), and the pack in this zip is the complete current node set - nothing requires a separate download.
