A proxy is basically just a scaled-down version of the original file or object used in place of the higher resolution one to reduce lag and ensure smooth playback. In other words, if you have something with high detail and resolution - such as a large video file or complex 3D model - then you would use a proxy to help manage its size and complexity.
Proxies are incredibly important for successful virtual productions because they ensure data doesn't slow down your workflow. By using lower-resolution versions of files instead of the originals, processors don't get bogged down by the strain of having to handle larger objects. Additionally, proxies help keep file sizes smaller so that more information can be loaded onto a machine without becoming overwhelming.
Regarding best practices for proxies in virtual production, there are a few key things to consider. First and foremost, remember that although proxy objects may look like the original ones, they must always be significantly smaller in size and resolution than their counterparts. Also, keep track of how many different proxies are being used on set at any given time; too many can confuse and create problems during editing later on. Finally, it's wise to find someone responsible for managing all of the proxies on the set; this will ensure everyone knows which proxy goes where and when.
