Proxy¶

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).

Proxy Settings¶

Reference

Panel:: Sidebar region ‣ Proxy ‣ Proxy Settings

Contains scene-wide proxy settings.

Storage

How proxies are stored for the project.

Per Strip:

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

Project:

All proxies are stored in one directory.

Proxy Directory: The location to store the proxies for the project.

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 View ‣ Proxy ‣ Setup.

Rebuild Proxy and Timecode Indices

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.

Strip Proxy & Timecode¶

Reference

Panel:: Sidebar region ‣ Proxy & Timecode ‣ Strip Proxy & Timecode

../../../../_images/editors_video-sequencer_sequencer_sidebar_proxy-panel.png

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

Custom Proxy

Directory: 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.
檔案: Allows you to use preexisting proxies.

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

Overwrite: Whether to overwrite existing proxy files or keep them.

Quality

Controls the level of lossy compression applied to the image, expressed as a percentage. Lossy compression reduces file size by discarding some image data, which may result in a loss of detail.

0%: Maximum compression, producing the smallest file size but the most noticeable quality loss.
100%: No compression, preserving full image quality at the cost of a larger file size.
