docs(minimax): document the FastH3 OmniRef reference-to-video workflow - #2117
workflow_templates shipped a separate eight-step checkpoint for reference-to-video, video_fasth3_ominiref_r2v (FastH3 OmniRef, min ComfyUI 0.43.0). The FastH3 tutorial still told readers that Ref2VA was not distilled and sent them to the base H3 pages, so the workflow had no documented entry point and the model download list was missing its diffusion file.
This PR documents the new workflow and the two smaller template additions from the same window:
FastH3 page (tutorials/video/minimax/minimax-h3-fastvideo): new FastH3 OmniRef Reference to Video section with preview, download card, reference image card, reference setup (ref_images up to 9 slots, ref_image_sizematch / max, duration grid), and prompting tips. The "Ref2VA was not distilled" note is replaced with the checkpoint split, the OmniRef diffusion model card and storage entry are added, the requirement line now carries 0.43.0, and the structure notes cover the OmniRef sigma shift (12 / 3) and its euler sampler at 8 steps.
Base MiniMax H3 page (tutorials/video/minimax/minimax-h3): getting-started versions list FastH3 OmniRef 0.43.0+, and the sampler/scheduler section notes the OmniRef shift pair.
HeyGen Voice page (tutorials/partner-nodes/heygen/heygen-voice-1): adds the api_heygen_voice_1_turbo template, which packages the same clone and speak pair with heygen-voice-1-turbo preselected. The model option itself was already documented.
All five locales (zh, ja, ko, es) are updated in the same commit and translationSourceHash / translationBlockHashes are refreshed.

Walkthrough
The tutorials add a HeyGen Turbo draft workflow and document FastH3 OmniRef reference-to-video use. They distinguish OmniRef from V2 by checkpoint, ComfyUI requirement, sampler, and shift settings. Translated pages also update translation metadata.
The tutorials add a Turbo workflow option using the existing clone-to-speech node pair, with heygen-voice-1-turbo preselected. Translated pages also update translation hashes.

Summary
OmniRef workflow and requirements */tutorials/video/minimax/minimax-h3-fastvideo.mdx
The guides distinguish the V2 and OmniRef workflows, specify their ComfyUI version requirements, and add OmniRef reference-image, sizing, duration, and prompting guidance.
Checkpoint downloads and storage */tutorials/video/minimax/minimax-h3-fastvideo.mdx
The guides add the OmniRef checkpoint download and storage details, distinguish its use from V2, and state that only one checkpoint should be loaded at a time.
Workflow sampler and shift settings */tutorials/video/minimax/minimax-h3-fastvideo.mdx, */tutorials/video/minimax/minimax-h3.mdx
The guides distinguish V2 and OmniRef sigma shifts and sampler settings. The companion FastH3 pages add OmniRef version and shift guidance.

Review comments at @es/tutorials/video/minimax/minimax-h3-fastvideo.mdx:
- Line 3: Shorten the description in the minimax H3 FastVideo frontmatter to 160
characters or fewer while preserving all supported workflows: text-to-video,
first/last-frame, and reference-based video generation.
- Line 125: Update the “Imágenes de referencia” description to state that the
example uses one image for both identity and location, referenced as Picture 1.
Review comments at @ja/tutorials/video/minimax/minimax-h3-fastvideo.mdx:
- Line 126: Update the Japanese reference-image description to match the linked
template: state that the example uses one image for both the plane and the
setting, rather than claiming it uses two images for a character and a location.
Review comments at @ko/tutorials/video/minimax/minimax-h3-fastvideo.mdx:
- Line 126: Update the reference-image instruction in the Minimax H3 FastVideo
tutorial to say the example uses one image for both the plane and the setting,
matching the linked template’s single connected reference image.
Review comments at @tutorials/video/minimax/minimax-h3-fastvideo.mdx:
- Line 116: Update the “Reference images” documentation in the Minimax H3
fastvideo tutorial to match the downloadable template’s single connected
reference image: describe the single-image setup and ensure the example prompt
assigns both the plane and setting to that image, without implying a second
image is available.
Review comments at @zh/tutorials/video/minimax/minimax-h3-fastvideo.mdx:
- Line 126: Update the “参考图” example in the tutorial to describe the single
reference image connected by the linked template and explain that the prompt
uses it for both subjects; do not describe the example as using two images.

workflow_templates added video_fasth3_ominiref_r2v (0.11.94), a separate
eight-step checkpoint distilled for reference conditioning. The FastH3 page
still said Ref2VA was not distilled and sent readers to the base H3 pages.
- add the OmniRef workflow section: preview, download card, reference image,
reference setup, prompting tips
- add the OmniRef diffusion model card and storage entry
- note the 0.43.0 requirement and the 12 / 3 sigma shift, and correct the
sampler note (OmniRef keeps 8 steps but selects euler)
- base H3 page: mention the OmniRef minimum version and its sigma shift
- HeyGen Voice page: add the HeyGen Voice 1.0 Turbo template card
