Замісник – 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 – Довідка

Panel – Панель:

Sidebar region ‣ Proxy ‣ Proxy Settings

Contains scene-wide proxy settings.

Сховище – Storage

How proxies are stored for the project.

По Смужках – Per Strip:

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

Проектування – Project:

Усі замісники зберігаються в одному каталозі.

Каталог Замісника – Proxy Directory

Локація для збереження замісників для проекту.

Задати Замісники Вибраних Смужок – 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.

Перебудувати Замісник та Індекси Часкоду – 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 – Довідка

Panel – Панель:

«регіон Бічносмуги > Замісник і Часкод > Замісник і Часкод Смужки» – Sidebar region ‣ Proxy & Timecode ‣ Strip Proxy & Timecode


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

Custom Proxy

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.

File – Файл

Allows you to use preexisting proxies.


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

Overwrite – Перезапис

Whether to overwrite existing proxy files or keep them.

Quality – Якість

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:

  1. Передобробити ваше відео за допомогою, наприклад, кодека MEncoder для виправлення заголовка файлу та вставки коректних ключкадрів.

  2. Use the Timecode Index option in Blender.

None – Нема:

Ignore generated timecodes, seek in movie stream based on calculated timestamp.

Record Run – Хід Запису:

Seek based on timestamps read from movie stream, giving the best match between scene and movie times.

Record Run No Gaps – Хід Запису Нема Пропусків:

Effectively convert movie to an image sequence, ignoring incomplete or dropped frames, and changes in frame rate.


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.
