代理

As projects involve increasingly high-resolution footage, the performance of the video preview can decrease drastically. To combat this, Blender can generate proxies — copies of the original footage stored at a lower quality and/or resolution — to maintain a smooth editing experience without compromising visual fidelity in the end result.

The quickest way to set up proxies for videos is to simply select a Proxy Render Size in the View tab (visible when the editor is in Preview or Sequencer & Preview mode). This will automatically enable the selected proxy resolution in all the strips and start generating the downscaled video files.

You can use the Proxy tab if you want to configure proxies in more detail (or create proxies for image sequences).

代理设置

参考

面板:

侧栏区块 ‣ 代理 ‣ 代理设置

Contains scene-wide proxy settings.

存储

如何为项目储存代理。

• 单个片段:

  Each strip can specify where to store its proxies (see below).

  投影:

  所有代理存储在一个目录。

  • 代理目录

    存储项目代理的位置。

设置已选中剪辑代理

Shows a pop-over that lets you choose the resolution(s) to generate and whether to overwrite existing proxy files. Once you confirm with the Set button, your choices are applied to the selected strips. You can view and tweak the settings for individual strips in the Strip Proxy & Timecode panel (see below).

In the Preview mode, where the Proxy tab is not available, this is instead done through the menu View ‣ Proxy ‣ Setup.

重建代理和时间码编号

Generates proxies and time indices for the selected strips.

In the Preview mode, where the Proxy tab is not available, this is instead done through the menu View ‣ Proxy ‣ Rebuild.

片段代理/时间码

参考

面板:

侧栏区块 ‣ 代理时间码 ‣ 片段代理时间码

Contains strip-specific proxy settings. The checkbox in the header can be used to enable/disable proxy generation.

自定义代理

• 文件夹

  By default, all generated proxy videos are stored to the folder <path of original footage>/BL_proxy/<clip name>, but this can be changed to a custom directory using this option.

  文件

  允许使用已存在的代理。

分辨率

The resolution(s) of the proxy videos to generate; multiple sizes can be selected.

覆盖

Whether to overwrite existing proxy files or keep them.

品质

代理的视频/图像品质。

时间码 编号

When you are working with footage directly copied from a camera without preprocessing it, there might be numerous artifacts, mostly due to seeking to a given frame in the sequence. This happens because such footage usually does not have correct frame rate values in the file header. This issue can still arise when the source clip has the same frame rate as the scene settings. In order for Blender to correctly calculate the frames and frame rate there are two possible solutions:

1. 使用例如MEncoder的软件对视频进行预处理，修复文件头并插入正确的关键帧。

2. Use the Timecode Index option in Blender.

• 无:

  忽略生成的时间码，根据计算的时间戳在电影流中请求。

  记录运行:

  根据从电影流中读取的时间戳进行搜索，以获得场景和电影时间之间的最佳匹配。

  无空隙录制运行:

  有效地将影片转换为图像序列，忽略不完整或丢失的帧以及帧速率的变更。

Note

Record Run is the Timecode Index which usually is best to use, but if the source file is totally damaged, Record Run No Gaps will be the only chance of getting an acceptable result.
