Proxy (Đại Diện)¶
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).

Địa điểm lưu trữ bản đại diện dùng thư mục của đề án.
- Đặt Tính Chất Đại Diện cho Dải được Chọn (Set Selected Strip Proxies)
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 .
- Tái Xây Dựng Chỉ Số của Đại Diện và Mã Thời Gian (Rebuild Proxy and Timecode Indices)
Generates proxies and time indices for the selected strips.

Whether to overwrite existing proxy files or keep them.
- Chất Lượng (Quality)
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:

Use the Timecode Index option in Blender.
- Không (None):
Ignore generated timecodes, seek in movie stream based on calculated timestamp.
- Quá Trình Thu (Record Run):
Seek based on timestamps read from movie stream, giving the best match between scene and movie times.
- Quá Trình Thu Không Cách Trống (Record Run No Gaps):
Effectively convert movie to an image sequence, ignoring incomplete or dropped frames, and changes in frame rate.
Ghi chú
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.
