The Clarity AI partner nodes gained a video upscaler next to the existing image upscaler (Comfy-Org/ComfyUI#17192, ClarityCrystalVideoUpscaleNode in comfy_api_nodes/nodes_clarityai.py), and the matching template api_clarity_ai_crystal_video_upscale shipped in Comfy-Org/workflow_templates#1364.

This adds a tutorial page for the new node and registers it in a new Clarity AI group under the partner-node Video navigation, in all four languages.

Facts taken from source:

• node ClarityCrystalVideoUpscaleNode, display name Clarity AI Crystal Video Upscale, model option crystal-video-upscaler, single scale_factor control (1.0 to 200.0, default 2.0)
• output caps: 9 megapixels per frame, 360 megapixel-seconds per clip, 5120 pixels per side; the factor is lowered automatically to fit
• clips above 30 fps bill 2x, above 60 fps 3x, and each additional 30 fps band adds another multiple
• the template is local-only (includeOnDistributions: ["local"]), so the Cloud card stays commented out until it is available in Comfy Cloud

Preview uses templates/api_clarity_ai_crystal_video_upscale-1.webp (the output mp4 is not in workflow_templates yet); input sample input/desert_highway_encounter.mp4 verified 200. The credit row for this node is in #2027.

📝 Walkthrough

Adds Crystal Video Upscale tutorials in four languages, documents node controls, workflow setup, limits, and pricing, and adds the tutorials to partner-node navigation.

Changes: Crystal Video Upscale documentation

Layer / File(s)	Summary
Tutorial controls and limits tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx, ja/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx, ko/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx, zh/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx	The tutorials describe video output behavior, scale_factor settings, pixel limits, and frame-rate pricing multipliers.
Workflow setup and use ja/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx, ko/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx, zh/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx	The tutorials add workflow downloads, sample input videos, execution steps, and getting-started instructions.
Pricing and navigation tutorials/partner-nodes/pricing.mdx, ja/tutorials/partner-nodes/pricing.mdx, ko/tutorials/partner-nodes/pricing.mdx, zh/tutorials/partner-nodes/pricing.mdx, docs.json	The pricing pages add resolution-based per-second rates and frame-rate multipliers. Navigation adds the tutorial in English, Chinese, Japanese, and Korean.

Suggested reviewers: comfyui-wiki

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 26c31

The new tutorial and pricing docs are mergeable. Before or soon after merge, fix the Korean and Chinese titles, state that the frame-rate multiplier keeps increasing above 60 fps, and move the video tutorial into Video navigation so readers can find it.

Architecture risk: 🔵 Low · up to 26c31

The change affects 5 systems.

under Video navigation, preserving their existing route values and ordering
conventions.

- Line 2: Update the frontmatter title in the tutorial so it begins with the
official model name, Clarity AI Crystal Video Upscaler, and describes the
ComfyUI video-upscaling capability without opening with “ComfyUI”; keep the
Korean title consistent with the existing English and Japanese titles.

Review comments at @tutorials/partner-nodes/pricing.mdx:
- Line 298: Update the frame-rate pricing descriptions in the English, Japanese,
Korean, and Chinese sections to state that the multiplier increases for each
additional 30-fps band beyond 60 fps, rather than implying all rates above 60
fps cost 3×.

Review comments at
@zh/tutorials/partner-nodes/clarityai/crystal-video-upscale.mdx:
- Line 2: Update the frontmatter title so the official model name “Clarity AI
Crystal Video Upscaler” comes first, followed by a Chinese description of its
ComfyUI video-upscaling capability; do not translate the model name or begin the
title with “ComfyUI”.

Checked against ClarityCrystalVideoUpscaleNode.execute in comfy_api_nodes/nodes_clarityai.py. One accuracy issue needs a fix, in all four languages:

The page says oversized or long clips "come back upscaled by less than the factor you asked for instead of failing" and that scale_factor is "Lowered automatically when the result would pass the frame or clip limit". The node raises an error on the source clip before upload:

• source frame over 9 MP → ValueError("... at most 9 megapixels per frame are supported ...")
• source duration over 360_000_000 / (w * h * ceil(fps / 30)) seconds → ValueError("... can be at most N seconds long ...")

The only automatic reduction is scale_factor = min(scale_factor, floor(5120 / max(w, h) * 100) / 100), which keeps the longest output side at 5120 px or less. The tooltip's "large or long videos are upscaled by less" may describe what the provider does with the output, but inputs over those limits are rejected client-side.

Suggested wording for Limits (EN):

• The source clip must be at most 5120 px on each side and at most 9 MP per frame. Its maximum length is 360 megapixel-seconds divided by the frame pixels and by ceil(fps / 30); for example, about 173 s for 1080p at 30 fps. Longer or larger clips are rejected.
• scale_factor is capped so the longest output side stays at or below 5120 px.

The intro paragraph and the "Graceful limits" bullet need the same correction. Everything else (single model option, 1.0 to 200.0 default 2.0, fps-based billing multiplier, URLs) checks out.
