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.
