What Is Proxy File in Video Editing?

When it comes to video editing, one term that you may come across is ‘proxy files.’ But what exactly are proxy files and how do they work? In this article, we’ll delve into the world of proxy files and explain everything you need to know.

What Are Proxy Files?

Proxy files are lower resolution versions of your original video footage. They are used in video editing software to help make the editing process smoother and faster.

When you import high resolution footage into your editing software, it can be resource-intensive and may cause playback issues. This is where proxy files come in. By using a lower resolution version of your footage, your computer can handle the playback more easily.

Why Use Proxy Files?

There are several reasons why you might choose to use proxy files in your video editing workflow:

  • Improved Performance: As mentioned earlier, using proxy files can help improve the performance of your editing software by reducing the strain on your computer’s resources.
  • Faster Editing: By using lower resolution footage, you can edit your videos more quickly as there is less data for the software to process.
  • Smaller File Sizes: Proxy files are usually much smaller in size than their high-resolution counterparts, making them easier to store and transfer.

How Do Proxy Files Work?

When you import your high-resolution footage into your video editing software, it will automatically create a corresponding proxy file in a lower resolution. This file will be used for playback and editing instead of the original high-resolution file.

Once you have finished editing your video, you can switch back to using the high-resolution file for export. The software will automatically replace all instances of the proxy file with the original footage.

Creating Proxy Files

Most video editing software will allow you to create proxy files in a few simple steps. Here’s how to do it in Adobe Premiere Pro:

  1. Right-click on your footage in the Project panel and select ‘Proxy > Create Proxies..’
  2. Select the resolution and codec you would like to use for your proxy files.
  3. Click ‘OK’ and wait for Premiere Pro to create the proxy files.


Proxy files are a useful tool for video editors looking to improve their workflow and speed up their editing process. By using lower resolution versions of your footage, you can improve performance, edit faster, and work with smaller file sizes. If you haven’t already tried using proxy files in your video editing workflow, it’s definitely worth giving them a try!
