Real-time video editing is a system of editing video where it takes no longer to render a video than the length of that video clip itself. For example, after a 30 minute length of video is edited it needs to be rendered, and should the system take more than 30 minutes to render the clip it is not a real-time system.

A lot depends on the effects, transitions, titles and other features - and quantity of features - added to the video prior to rendering it. The more the effects being applied the more the power required from the system to render the video in real-time. Systems designed for web or mobile publishing often handle smaller images sizes than those designed for DVD output, and can render effects in real time quite easily.
