❌ 一步 4倍
✅ 分多步,每次 1.5x / 2x❌ 1x → 4x direct
✅ Step by step (1.5x)
过低是马赛克,过高是换脸。
需精准控制。Too low = Pixelated
Too high = Identity shift
❌ 加新内容 (New dress)

包含 SD Upscale, TTP Upscale 等。Includes SD Upscale, TTP Upscale.
偏向工程修复,减少过度美化。Engineering restoration, less beautification.
动漫/二次元专属放大,线条处理极佳。Anime specific. Excellent line handling.
图像已经“不可救”时的最后手段。Last resort for "unsalvageable" images.
现在的真实需求不再是“无损放大”,而是“洗图 (Washing/Polishing)”——即“更好看 + 还是同一个东西”。 The real demand isn't "Lossless", but "Polishing" — "Better looking + Same identity".
视频模型的一致性优势是“换来的”:它们牺牲了极端的细节自由度,换取了全局的结构稳定性。对大多数人来说,“不翻车”比“最惊艳”更重要。 Video models trade "detail freedom" for "structural stability". "Not failing" is more important than "Amazing".
