Proxy clips create a lower-quality transcode of the original footage for use in real-time rendering in the project monitor. This allows for a smoother editing experience even on slower computers with High Definition footage. When rendering, by default, the original quality footage is used and not the proxy footage. For example, Video decoding of H.264 or H.265 clips, requires a lot of computing power to decode and could cause playback stutter when rendering effects in real time.
