<h3>⚠️ 发现的问题</h3>
|
||||
<ul>
|
||||
<li><strong>编码转换损失</strong>: HEVC → H264 转码导致质量下降,尤其是亮度通道</li>
|
||||
<li><strong>PSNR 偏低</strong>: 23.37 dB 表示存在明显的压缩伪影和细节损失</li>
|
||||
<li><strong>亮度细节受损</strong>: Y 通道 PSNR 仅 21.72 dB,细节模糊化明显</li>
|
||||
<li><strong>压缩算法不同</strong>: 微信使用了更激进的压缩策略</li>
|
||||
</ul>
|
||||
</div>
|
||||
|
||||
<div class="findings good-news">
|
||||
<h3>✅ 保留较好的方面</h3>
|
||||
<ul>
|
||||
<li><strong>分辨率不变</strong>: 依然保持 1080×1920 的原始分辨率</li>
|
||||
<li><strong>色彩保留好</strong>: 色度通道 PSNR > 33 dB,色彩还原度较高</li>
|
||||
<li><strong>结构相似度高</strong>: SSIM 0.873 说明整体结构和内容保持良好</li>
|
||||
<li><strong>码率基本不变</strong>: 从 6.89 → 6.91 Mbps,带宽消耗相近</li>

||||

<h3 style="color: #0066cc; margin-bottom: 15px;">💡 技术解释</h3>
|
||||
<p style="color: #004080; line-height: 1.8; margin-bottom: 10px;">
|
||||
<strong>为什么感觉模糊?</strong><br>
|
||||
主要原因是微信视频号将你的 HEVC(H.265)视频重新编码为 H264(H.265 压缩效率更高)。
|
||||
虽然码率几乎相同,但 H264 在相同码率下的画质不如 HEVC,导致细节损失。
|
||||
</p>
|
||||
<p style="color: #004080; line-height: 1.8; margin-bottom: 10px;">
|
||||
<strong>PSNR 和 SSIM 含义:</strong><br>
|
||||
• PSNR > 30 dB: 优秀<br>
|
||||
• 20-30 dB: 有损压缩,可见损失<br>
|
||||
• SSIM > 0.9: 几乎无损<br>
|
||||
• 0.8-0.9: 轻微损失<br>
|
||||
你的视频 PSNR=23.37, SSIM=0.873,属于典型的有损压缩。
|
||||
</p>
|
||||
<p style="color: #004080; line-height: 1.8;">
|
||||
<strong>建议:</strong><br>
|
||||
如果希望保持更好的画质,可以尝试上传前降低原始视频的码率(如 4-5 Mbps),
|
||||
这样微信重新编码时损失会更小。或者直接上传 H264 编码的视频。
