Seedance 480p升级4K对比展示

👇看好了：这是人们要求的证明；30秒的Seedance 2.5 480p → 使用Topaz进行4K放大。上面是Topaz 4K，下面是480p源。同一帧。 从:04开始观看特写镜头，以获得最佳的主体对比，其中放大后的细节最明显。（最好全屏比较） 💻 过程： 这个片段是使用Topaz的“Rhea”模型进行4倍放大的。我们原始21:9宽高比片段的分辨率提升到了：3440x1498 “Proteus”模型更适合720p的一般放大；而“Rhea”让480p素材看起来和从720p或1080p放大的4K片段一样好。 💭想法： 使用Rhea的唯一缺点是渲染时间，如果你的硬件不够好，以及渲染时会有明显的轻微颗粒感。否则，如果你想要480p片段的锐利清晰度，我完全推荐Rhea而不是Proteus。对于一般放大和速度，坚持使用Proteus，它也会降低锐度，获得漂亮的柔和电影感。 皮肤保持纹理而不是塑料感，布料编织纹理回来了，背景细节也填充了。 🗒️备注： [由于X的视频压缩，差异在这里可能看起来微妙。我知道很多这类对比会故意柔化低分辨率一侧，以使跳跃看起来更大。这里保持真诚。成本明细即将推出。]

👇BEHOLD: The proof people asked for; 30 seconds of Seedance 2.5 480p → Topaz 4K using upscaling. Topaz 4K on top, 480p source below. Same frame. Watch the closeups from :04 onwards for the best comparison of the subject for where the most detail in the upscale is visible. (Best compared on full screen) 💻 The Process: This clip was upscaled using Topaz's "Rhea" model, which does 4x upscaling. With the resolution of our original 21:9 aspect ratio clip increased to: 3440x1498 The "Proteus" model is better for general upscaling of 720p; "Rhea" makes 480p footage look as good as 4K clips upscaled from 720p or 1080p. 💭Thoughts: The only downside for using Rhea is the render time if you aren't running on decent hardware and a noticable, slight grain on renders. Otherwise, I wholly recommend Rhea over Proteus if you want razor sharpness in 480p clips. For general upscaling and speed, stick with Proteus which also dials back the sharpness for the nice soft filmic look. Skin holds texture instead of going plastic, the cloth weave comes back, and the background details fill in. 🗒️Note: [Differences may seem subtle here due to X's video compression. I know a lot of these comparisons soften the low-res side on purpose to make the jump look bigger. Keeping it sincere here. Cost breakdown coming soon.]
