| ## ComfyUI-H3-Prompt-IDE |
|
|
| The nightly prompt-editor completion, marker-interaction, tokenizer diagnostic |
| and preference improvements are selectively adapted from |
| [ComfyUI-H3-Prompt-IDE](https://github.com/ethanfel/ComfyUI-H3-Prompt-IDE) |
| at revision `8d3bccf11291096da4e0150e2e6fc23b014967d1`, GPL-3.0. |
| That standalone editor originally derives from this repository's rich editor. |
|
|
| The adaptations live in `web/h3_prompt_completion_core.mjs`, |
| `web/h3_prompt_schema_core.mjs`, `web/h3_prompt_marker_ui.mjs`, |
| `web/h3_prompt_editor_settings_core.mjs`, and both embedded editor surfaces. |
| Chain-specific tagged/semantic reference mapping, per-scene undo, Plan |
| synchronization and ownership protection remain local. The standalone |
| task-aware Edit templates and native-undo replacement are not incorporated. |
|
|
| ## ComfyUI-LegacyWidgetWidthFix |
|
|
| The canvas-wide LiteGraph widget-width compatibility layer is adapted with |
| permission from |
| [ComfyUI-LegacyWidgetWidthFix](https://github.com/pekkAi-dev/ComfyUI-LegacyWidgetWidthFix) |
| by **pekkAi-dev**. This pack embeds the repair behind its existing H3 nodes and |
| does not claim or register the standalone project's `LegacyWidgetWidthFix` |
| node id. Shared legacy widget marker names are retained deliberately so both |
| extensions can coexist without stacking incompatible widget descriptors. |
|
|
| ## ComfyUI-H3-Motion-Context |
|
|
| This repository grew from the original H3 Motion Context implementation by |
| **NikoDemon80**: |
|
|
| https://github.com/NikoDemon80/ComfyUI-H3-Motion-Context |
|
|
| The shared initial implementation and research remain under this repository's |
| GPL-3.0 license and are preserved in its Git history. Niko's project owns the |
| original `MiniMaxH3MotionContext*` public node ids. This specialized loop pack |
| uses separate registrations while vendoring upstream's shared marker and |
| patch-ownership ABI, allowing both projects to be installed without registering |
| the same nodes or double-wrapping ComfyUI. |
|
|
| `patch_layout.py` and `patch_payload.py` retain the shared ownership markers |
| from upstream revision `c140ae99b8c3` (`0.2.0`, 2026-08-09). This loop fork |
| extends the layout implementation with native-guide capability detection while |
| preserving that ownership ABI for safe co-installation on legacy ComfyUI. |
|
|
| Upstream revision `658ba11ae917` (`0.3.0`, 2026-08-12) by **NikoDemon80** is |
| also the source of the retained `last_frame` design, 56-frame context option, |
| and the in-graph Seam Probe adapted here. This fork gives the probe a distinct |
| public node id so both packs can remain installed together, and retains its own |
| native-guide and recursive-chain integration. |
|
|
| ## ComfyUI-H3-Motion-Context-MultiRef |
|
|
| The cumulative audio-sample budgeting approach was inspired by |
| [ComfyUI-H3-Motion-Context-MultiRef](https://github.com/seitanism/ComfyUI-H3-Motion-Context-MultiRef) |
| by **seitanism**. This repository implements the idea independently for its |
| checkpointed generated-audio and saved-prelude assembly, using cumulative |
| delivered video-frame boundaries so per-scene rounding cannot accumulate into |
| long-run A/V drift. |
|
|
| On the nightly integration, `motion_context_upstream.py` dynamically discovers |
| that pack's public `MiniMaxH3MotionContext` registration and calls it for |
| compatible Guide scenes. No upstream source is copied by this adapter. The |
| visible Chain node and saved workflow remain local; capability checks retain |
| the internal implementation for Loop-only modes the upstream contract does not |
| yet expose. This runtime integration was reviewed against upstream revision |
| `5839d453efa0346c1da49acc39fc65050c5c48c0` (2026-08-30), GPL-3.0. |
|
|
| The retained internal fallback was also brought to that revision's arbitrary |
| Guide-length and `target_start` placement behavior. `h3_audio_grid.py` adapts |
| the same revision's exact 40 Hz PCM-grid helper so source-audio continuation |
| cannot be shifted by a generic VAE wrapper's normal center crop. Local |
| keyframe arbitration, latent Guide, audio-only and longer-audio continuity, |
| signed fractional audio placement, and legacy-core support |
| remain extensions of this loop pack. |
|
|
| The experimental masked AV chain mode directly adapts that GPL-3.0 project's |
| masked existing-video extension and its capability-aware runtime compatibility |
| for ComfyUI PR #15375. In this loop integration the preserved source is the |
| previous accepted scene checkpoint: decoded tail frames are VAE-encoded into |
| the next target video latent, its sampled audio-latent tail is copied directly, |
| and both target prefixes receive `0 = preserve`, `1 = generate` masks. |
|
|
| Adapted source files and integration: |
|
|
| - `h3_mask_compat.py` — PR #15375 model/sampler capability detection and |
| fallback; |
| - `h3_mask_payload_compat.py` — native-first AV mask payload extraction; |
| - `masked_context.py` — recursive target-prefix construction derived from the |
| MultiRef existing-video implementation, including Update 6's audio-only |
| eight-tick half-cosine handoff as a distinct continuation mode. |
| - `master_audio_context.py` — exact master-audio target replacement and |
| optional protected video-prefix construction adapted from MultiRef Update 4, |
| plus Update 6's direct sampled-latent video continuation path. |
| - `av_timing.py` and `nodes.py` — Update 6's exact absolute PCM-boundary and |
| small decoded-audio time-conformance approach, adapted to the recursive |
| checkpointed trim path. |
| - `masked_bridge.py` — two-ended protected AV target construction adapted |
| from MultiRef Update 5's masked bridge. |
|
|
| The referenced MultiRef revision is `4b484a3` (2026-08-14), GPL-3.0. |
| Its v2 mask-engine marker is recognized for safe migration. This pack uses a |
| v3 model, sampler, and payload ABI for PR #15375 commit `989e7a9`, replacing |
| only recognized older blend/payload wrappers whose semantics changed. |
|
|
| The master-audio node adapts MultiRef Update 4 at merged revision `9118251` |
| (2026-08-14) and its Update 5 target-audio-grid boundary correction at merged |
| revision `31e6cb7` (2026-08-15). Absolute master-audio slice endpoints and |
| small decoded-audio time-conformance follow Update 6 revision |
| `56f7586597929c43a6373ef28f6f84f26411b223` (2026-08-17). |
|
|
| The two-ended masked bridge adapts MultiRef Update 5 at merged revision |
| `31e6cb7` (2026-08-15). |
|
|
| ## ComfyUI MiniMax H3 per-token AV masks |
|
|
| The underlying per-token video/audio latent masking design and upstream |
| implementation are from |
| [ComfyUI PR #15375](https://github.com/Comfy-Org/ComfyUI/pull/15375), authored |
| by **drozbay**. The vendored fallback is scoped to masked target-latent |
| operations, prefers native equivalent behavior automatically, and is not |
| activated by ordinary guide-mode chains. It tracks the post-review mask-blend |
| design through upstream commit `989e7a9bb79a370d20f63674b54dead993f6f4a1` |
| (2026-08-15). |
|
|
| ## MaskVidExperiments causal mask conversion |
|
|
| The exact H3 pixel-mask conversion in `masking_ops.py` adapts the causal |
| frame-group derivation, conservative max reduction, and 2×2 latent-token |
| snapping from |
| [MaskVidExperiments](https://github.com/drozbay/MaskVidExperiments) by |
| **drozbay**. This integration specializes that general VAE-aware algorithm to |
| MiniMax H3's fixed `1,4,4,4,4` frame cycle and existing joint-AV masked target; |
| it does not copy the upstream crop, uncrop, or workflow nodes. |
|
|
| The referenced revision is |
| `d98cc899c1fac718acf81cde1735bf57281097cf` (2026-08-17), GPL-3.0. |
|
|
| ## ComfyUI-MiniMaxH3-PerRowMasking |
|
|
| The public general-masking workflow and its source-media/mask-grid utilities |
| adapt the earlier experimental |
| [ComfyUI-MiniMaxH3-PerRowMasking](https://github.com/ethanfel/ComfyUI-MiniMaxH3-PerRowMasking) |
| repository by **ethanfel**. That GPL-3.0 project established the source AV |
| `17k+5` trim, exact 32×32 effective-cell preview, mask-convention controls, |
| source-latent workflow, and audio-preservation UI used as the starting point. |
|
|
| This integration uses revision `d6a7964b9fd64f65f1773f84cba3b29665128e59` |
| (2026-08-07). It does not copy that project's temporary per-model forward |
| wrapper. Instead, Apply Target Mask reuses this pack's newer capability-aware |
| PR #15375 engine, composes existing nested masks, and exposes additional |
| temporal/custom audio-mask modes under distinct node IDs for safe co-install. |
|
|
| ## ComfyUI MiniMax H3 Add Guide |
|
|
| Native-guide compatibility targets |
| [ComfyUI PR #15439](https://github.com/Comfy-Org/ComfyUI/pull/15439), authored |
| by **drozbay**. That contribution introduces arbitrary-position image, video, |
| and audio guides plus native keyframe/reference payload merging in ComfyUI. |
| This repository does not copy its node implementation; it detects the exposed |
| core layout API and emits compatible guide records from Loop Context. |
|
|
| ## MiniMax H3 Chained Character Swap |
|
|
| The opt-in `tapered_guide` continuation adapts the tapered chroma-noise context |
| recipe, palette, validated default strengths, and deterministic-noise design |
| from [minimax-h3-chained-character-swap](https://github.com/MacroSony/minimax-h3-chained-character-swap) |
| by **MacroSony**. This integration applies the transformation in memory to an |
| immutable clone of the exact recursive context tail, derives its noise seed |
| from the scene seed, and generalizes the published 22-frame baseline to other |
| explicit Guide lengths as an experimental option. |

|
| ## ComfyUI-H3-Context-Noise |
|
|
| The experimental `tapered_av` / Detail AV transition adapts the latent |
| Gaussian context-noise recipe, matched-latent-standard-deviation scaling, |
| validated 0.45 to 0.10 two-step taper, and deterministic CPU-noise design from |
| [ComfyUI-H3-Context-Noise](https://github.com/beijinren/ComfyUI-H3-Context-Noise) |
| by **beijinren**. This integration applies the treatment only to an immutable, |
| disposable copy of the recursive 39-frame video-latent prefix, leaves the |
| audio latent and denoise masks unchanged, and fingerprints the recipe for safe |
| checkpoint resume. |

| ## ComfyUI-MiniMaxH3-Easy |
|
|
| The H3 Chain Plan editors' quick `@` reference-tag and `#` dialogue-tag |
| interactions, rich reference chips, media miniatures, compact optimizer |
| presentation, and direct-provider transport pattern were inspired by |
| [ComfyUI-MiniMaxH3-Easy](https://github.com/nkxx188/ComfyUI-MiniMaxH3-Easy) |
| by **nkxx188**. The graph-aware scheduled-reference mapping, scene-card editor, |
| plan serializer, prompt revision storage, MCP agent bridge integration, |
| H3-scoped instruction/context contract, timing calculations, and chain |
| integration in this repository are an original implementation. |
