What is a proxy in the context of Adobe Premiere Pro?

In the context of Adobe Premiere Pro, a proxy refers to a low-resolution file created specifically to facilitate smoother editing workflows. When working with high-resolution footage, such as 4K or higher, these files can be very large and demanding on the system, which may lead to playback lag and slow responsiveness during editing. By creating proxies, editors can work with smaller files that are easier for the system to manage, allowing for a more fluid editing experience without compromising the final output quality.

Once the editing process is complete, the project can be rendered using the high-resolution files, ensuring that the final product maintains its intended quality. This approach is particularly beneficial for projects that require substantial visual effects, color grading, or intricate editing, where performance can be a concern when dealing with extensive high-res media.
