自2025年11月30日起，本站多媒体画质将全面升级：
- 视频端：所有视频升级为超高清画质，采用最新的AV1编码技术。在画质与原版几乎无差异的前提下，体积相比现有格式至少减少60%-70%。
- 图片端：全部图片采用原画质量的WEBP格式，画质与原版一致，体积大幅优化。
- 设备兼容性：因AV1编码特性，若设备不支持将无法播放视频。本站未采用格式降级技术（部分大平台会自动切换兼容格式），2019年及以后发布的设备基本都支持，具体可参考以下兼容性参考表。
Starting from November 30, 2025, the multimedia quality of our site will be fully upgraded:
- Video Segment: All videos will be upgraded to ultra-high-definition quality, adopting the latest AV1 encoding technology. With almost no difference in picture quality compared to the original version, the file size will be reduced by at least 60%-70% compared to the existing format.
- Image Segment: All images will use the WEBP format with original picture quality. The picture quality is consistent with the original, and the file size is greatly optimized.
- Device Compatibility: Due to the characteristics of AV1 encoding, videos will not be playable if your device does not support it. Our site does not adopt format degradation technology (some major platforms will automatically switch to compatible formats). Devices released in 2019 and later generally support it. For details, please refer to the following compatibility reference table.
