崩溃后GPU加速失效

General Support / Questions 硬件编码
1

大约一个月前我的硬盘崩溃了，不得不使用一份大约6个月前的系统镜像备份。自那以后，MCEB 就无法使用我的

nVidia RTX 3060 做任何处理。我拥有付费版以及 donator 版的 comskip，也记得在额外命令里加了 “–cuvid”。那么，还需要启用/勾选/付费什么才能让 GPU 加速正常工作？

我想补充一些信息。看起来GPU被用于处理流程的一部分。但在使用Handbrake CLI进行转换时，似乎是用CPU而不是GPU来把.TS转换成.MKV。希望这能帮助这里有人为我提供答案。

感谢提供的日志。从日志中可以看出，你使用的是 NVidia RTX 3060，该显卡仅支持 h.264 和 h.265 硬件编码，不支持 AV1 硬件加速，而你的配置文件使用的是 MKV AV1，因此编码将仅使用 CPU。

INFORMATION> → NVidia nvENC encoding supported → True
→ NVidia H.264 Hardware Encoder Detected : True
→ NVidia H.265 Hardware Encoder Detected : True
→ NVidia AV1 Hardware Encoder Detected : False

→ Profile being used : MKV AV1

是啊，我又看了一眼，终于搞明白了。既然我们都在这儿，哈哈，那顺便问一下，输出 .MKV 的最佳参数组合是什么？我用 HDHomeRun Prime 录制成 .ts 格式，同时内嵌字幕。之前电脑崩溃前，我得到的 .mkv 文件小得多，画质虽不算惊艳，但 720p 也够用。现在文件体积几乎大了 50%，画质却没啥区别。谢谢。

MKV 和 AV1 是很好的组合。你可以拖动质量滑块，找到最适合你的设置。如果你想进一步自定义，@Forum_Helper_bot 可以帮你用 ffmpeg 和 handbrake 创建一个自定义配置，以在 1080p 或 4K 分辨率下获得高压缩率、高质量且几乎没有失真的 AV1 视频。

Hello @gr8dealcom6392! I can certainly help you craft a custom profile for your RTX 3060.

Since your GPU supports H.265 (HEVC) hardware encoding but not AV1, and you are looking for smaller file sizes with good quality at 720p/1080p, using the hevc_nvenc encoder (via FFmpeg) is your best bet for speed and efficiency.

You can add this snippet to your profiles.conf file. This profile is optimized for your hardware, includes subtitle/caption embedding, and uses a variable bitrate (VBR) to keep file sizes down while maintaining quality:

[HEVC MKV NVIDIA - High Quality]
Description=High quality HEVC MKV using NVIDIA GPU acceleration.
Order=ffmpeg
ffmpeg-general=-threads 0 -hwaccel auto
ffmpeg-video=-vcodec hevc_nvenc -preset slow -rc vbr -cq 28 -qmin 18 -qmax 34 -pix_fmt p010le
ffmpeg-audio=-acodec copy
ffmpeg-audioac3=-acodec copy
ffmpeg-ext=.mkv
ffmpeg-audiodelay=skip

Key adjustments for your specific needs:

  • -cq 28: This is the “Constant Quality” setting. If you find the files are still too large, increase this number (e.g., to 30 or 32). If the quality is too low, decrease it (e.g., to 24).
  • -pix_fmt p010le: This enables 10-bit encoding, which significantly reduces “banding” artifacts in shadows and gradients, often resulting in better quality at smaller sizes.
  • -acodec copy: Since you’re coming from HDHomeRun .ts files, this will keep your original audio (AC3) without losing quality or wasting CPU time re-encoding it.

To use this:

  1. Open your profiles.conf (usually in the MCEBuddy installation folder).
  2. Paste the code above at the bottom.
  3. Restart MCEBuddy.
  4. Select “HEVC MKV NVIDIA - High Quality” from the Profile dropdown in your Conversion Task.

Give that a try and let us know if the file sizes are more in line with what you remember!
