Adds an Astra 2 page under **Partner Nodes / Topaz** (en/zh/ja), matching the existing partner-node convention (frontmatter, `ReqHint`/`UpdateReminder` snippets, key capabilities, pricing, model id, parameters, examples).

Supersedes #956 — please close that one. The previous build also placed the page under `built-in-nodes`; this PR moves it to `tutorials/partner-nodes/topaz/astra-2` and updates `docs.json` navigation in all three languages.

Astra 2 は Topaz Labs の次世代クリエイティブ拡散モデルベース動画アップスケーラーで、ComfyUI のパートナーノードとして利用できます。Astra 1 をベースにディテール生成とスタイライズの制御を強化し、AI 生成映像に新しいダイナミックなディテールやテクスチャを追加します。創造性・シャープネスの調整やプロンプトによるガイドにより、より精密なクリエイティブ表現が可能です。

Astra 2 はスタイライズ素材や GenAI 素材、ワイドショット、大規模なシーンなど、ディテールをクリエイティブに補完できる映像で最も効果を発揮します。映像の鮮明さ・豊かさ・視覚的複雑度を向上させ、表現力の高いスタイライズワークフローに最適化されています。

## 主な特徴

- **クリエイティブなディテール生成** — 既存ピクセルをシャープにするだけでなく、新しいテクスチャやディテールを追加。
- **拡張された制御** — 調整可能な創造性・シャープネスと、任意のプロンプトによるガイドで、クリエイティブな方向性を細かく制御。
- **スタイライズ/ワイドショットに強い** — スタイライズ、GenAI、ディテールの少ないシーンに最適化。

title: "Astra 2 - Creative diffusion video upscaling"
description: "Use Topaz Astra 2 in ComfyUI to creatively upscale GenAI video with adjustable creativity, sharpness, and prompt-based guidance."
sidebarTitle: "Astra 2"

import ReqHint from "/snippets/tutorials/partner-nodes/req-hint.mdx";
import UpdateReminder from "/snippets/tutorials/update-reminder.mdx";

Astra 2 is Topaz Labs' next-generation creative diffusion-based video upscaler, available as a partner node in ComfyUI. Building on Astra 1, it adds expanded control over detail generation and stylization, and transforms AI-generated footage by introducing new dynamic detail and texture with adjustable creativity, sharpness, and prompt-based guidance.

Astra 2 performs best on stylized and GenAI sources, as well as wide shots and large-scale scenes where additional detail can be creatively inferred. It enhances clarity, richness, and visual complexity, and is optimized for expressive, stylized workflows.

## Key capabilities

- **Creative detail synthesis** — Adds new texture and detail to GenAI sources rather than only sharpening existing pixels.
- **Expanded control** — Adjustable creativity and sharpness levels, plus optional prompt-based guidance for precise creative direction.
- **Strong on stylized and wide-shot content** — Optimized for stylized, GenAI, and detail-sparse scenes.

import ReqHint from "/snippets/zh/tutorials/partner-nodes/req-hint.mdx";
import UpdateReminder from "/snippets/zh/tutorials/update-reminder.mdx";

Astra 2 是 Topaz Labs 的新一代创意扩散视频放大模型,作为合作伙伴节点在 ComfyUI 中提供。它在 Astra 1 的基础上扩展了对细节生成与风格化的控制能力,能够为 AI 生成的视频添加新的动态细节与纹理,提供可调的创意强度、锐化控制以及基于提示词的引导,让创意方向更加精确。

Astra 2 在风格化和 GenAI 素材、广角镜头以及大场景中表现最佳,可以创造性地补充新的细节,从而提升画面的清晰度、丰富度与视觉复杂度,特别适合富有表现力的风格化工作流。

## 主要能力

- **创意细节合成** — 为 GenAI 素材生成新的纹理与细节,而不仅仅是锐化已有像素。
- **更强控制** — 提供可调的创意强度与锐化等级,以及可选的提示词引导,便于精确控制创意方向。
- **擅长风格化与广角内容** — 针对风格化、GenAI 与细节稀疏的场景进行了优化。
