《章鱼噼的原罪》原盘整体没有太多瑕疵，但画面中的细腻动噪处理起来相当棘手。其视觉强度不上不下，同时又存在一定程度的欠码：如果保留原样，在 HEVC 编码下很难完整呈现；如果直接降噪，又会影响原本的画风。
在厨力的驱使下，我们在本项目中大胆改用了 AV1 格式，借助其噪点生成（FGS, Film Grain Synthesis）功能来解决噪点保留问题。通过分析 AV1 编码器的设计和特性，我们摸索出了一套更适配的参数组合，以及配套的后期处理逻辑，尽可能克服 AV1 格式在细节保留上“下限低，上限更低”的缺点。
在 FGS 方面，我们并未采用编码器自带的 --film-grain 功能，而是构建了新的工具链，用于提取原盘的噪点特征，并准确重现符合原本画风的噪点。
最终得到的画面效果让我们相信，本次投入的时间和精力是值得的。而且由于噪点是通过生成而非直接编码的方式保留，成品体积甚至也得到了一定优化。
以此项目为契机，我们也希望日后能有更多噪点番采用 AV1 + FGS 来克服技术困难，以更好的面貌呈现到大家面前。
The source of "Takopi's Original Sin" generally has few artifacts, but the fine dynamic noise remains quite tricky to process. Its visual intensity is moderate, and it suffers from some insufficient bitrate. If left unchanged, HEVC encoding struggles to reproduce it fully; if denoising is applied directly, it affects the original art style.
Driven by our passion, we boldly switch to the AV1 format in this project. We utilize its Film Grain Synthesis (FGS) feature to solve the noise retention issue. By analyzing the design and characteristics of the AV1 encoder, we discover a more suitable combination of parameters and corresponding PP logic. This helps us best overcome the AV1 format's flaw of having a "low floor, and an even lower ceiling" in detail retention.
For FGS, we do not use the encoder's built-in --film-grain feature. Instead, we build a new toolchain to extract the noise characteristics of the source and accurately reproduce noise that matches the original art style.
The final visual result proves that our invested time and effort are worthwhile. Moreover, since the noise is preserved through synthesis rather than direct encoding, the final file size is even optimized to some extent.
Using this project as an opportunity, we hope that more grainy anime adopt AV1 + FGS to overcome technical difficulties and present a better look to the audience.
