Working with Proxy

Once all the video clips you’d like to use in your next video are transferred from the camera to a computer and organized properly, you can start thinking about the most efficient way of piecing them together.

That’s where the creation of proxy files comes in, as you don’t have to work with the original size RAW files. Instead, you can create proxies that are significantly smaller than the video files your camera has captured and still export the video in the 4K or UHD resolution.

This is a simple and yet very effective video editing technique that makes the video editing process much smoother since it will shorten the amount of time your computer needs to render previews or perform any other video editing task.

What is Proxy Video Editing and How Does a Proxy Work?

Proxy video editing is a great option if the computer you’re using for editing has a modest amount of RAM or if its processor is not powerful enough to support the demanding tasks of applying complex visual effects.

Even though proxy files can shorten the amount of time you need to spend in the editing room, this video editing technique is only useful in a particular context. So what are the benefits of proxy video editing, exactly?

When Should You Use Proxy Video Editing?

Whether or not you can benefit from using proxy files during the video editing process depends on how powerful the computer you are using to edit videos is.

If you have a laptop or a desktop computer that meets all of the video editor’s advanced technical specifications, then creating proxy files won’t boost the software’s performance significantly.

However, if you are editing on a device that is primarily designed for web browsing or an older model of a PC or a Mac computer, then reducing the resolution of the files you use in your projects can save you some time or even prevent the software from crashing at a crucial moment.

How to Create and Use Proxy in Filmora

Video content creators who often shoot their videos with action cameras and other devices that can record video in 4K resolution can easily create proxy files in Filmora.

So, once you’ve installed Filmora on your Mac or PC computer, you should just double click on its desktop icon and after the app’s welcome window pops up on the screen, you should just click on the New Project option.

Head over to the File menu, when the new project opens and locate the Preferences option. Alternatively, you can use the CTRL+SHIFT+, keyboard shortcut to bring up the Preferences window and then click on the Performance tab.

Make sure that the Enable GPU Acceleration option is activated by clicking on the appropriate checkbox and proceed to select your computer’s graphics card from the drop-down menu. Click on the checkbox that is located next to the Automatically create proxies when media resolution is higher than: option in the Proxy menu, and then pick either 1280x720p or 1920x1080p resolution. You can also choose a folder on your computer’s hard drive where all proxy media files are going to be saved by clicking on the Browse button in the Proxy Location submenu.

In case you want to delete all proxy files you created after you’ve completed a project, you can enable the Automatically delete proxies when a project is closed option and then click on the OK button to confirm the changes.

Go to the Media Panel to start importing media files you’d like to use in your project and Filmora will automatically create proxies for each file that has a resolution that is higher than the resolution you’ve specified earlier.

Keep in mind that the amount of time Filmora is going to need to create proxy files depends on the size of source files and the number of files you are transcoding at the same time.
