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).

- 单个片段:
Each strip can specify where to store its proxies (see below).

- 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 .
- 重建代理和时间码编号
Generates proxies and time indices for the selected strips.

- 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

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

Whether to overwrite existing proxy files or keep them.
- 品质
The video/image quality for proxies.
- Timecode Index
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:
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。
使用Blender中代理/时间码选项。
- 无:
不使用任何时间码。
- 记录运行:
按图像的记录顺序使用图像。
- 自由运行:
使用录制设备编写的全局时间戳。
- 自由运行:
使用记录设备编写的记录日期和时间插入全局时间戳。
- 无空隙录制运行:
Similar to Record Run, but ignores the timecode given in the file header, changes in frame rate, or frame dropouts.
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.
