When using Descript, you might notice that your media occasionally looks different than expected—such as slightly pixelated visuals or lower audio quality. This happens because Descript automatically creates optimized proxy files to improve editing performance. These files help keep playback smooth and responsive while reducing strain on your computer.
What Are Optimized Files?
When you import or record media in Descript, the app generates an optimized version of your file. These proxy files allow for faster playback and smoother editing by reducing file size and system load. While the optimized file may appear lower in quality, it does not affect your final export—Descript always uses your original files when exporting.
Your final export will always use the original, high-quality media files. If you want to check the final resolution, export your project.
How Optimized Files Improve Performance
Optimized files provide a smoother editing experience by reducing lag and improving playback speed.
- Faster scrubbing and navigation – Move through your project without delays.
- Less system strain – Work with large files without overloading your computer.
- Seamless cloud storage – Your original files remain in the cloud, while optimized files are stored locally for editing.
Even though Descript uses proxies for editing, your final export always maintains full resolution and audio quality.
Disabling Optimized Files
If you’re using a high-performance computer and prefer to work directly with original files, you can disable optimized file creation. However, keep in mind that this may slow down playback and increase system load.
From the Drive View
- Select your profile icon in the top right corner and choose Settings.
- From the General tab, turn off Optimize video files for playback in the Advanced section.
From the Editor
- Open a project and open the menu in the top left, then select Settings.
- From the General tab, turn off Optimize video files for playback in the Advanced section.
Manually Creating Optimized Files
If you disable automatic optimization, you can still manually create optimized assets from the Project panel. Learn more about manually optimizing files.
By using proxy files, Descript ensures that your editing experience stays fast and responsive while keeping your final content high-quality.
