DGIndex is one of the most versatile and important tools available to digital video enthusiasts. As a standalone program it can give detailed information about MPEG-1 and MPEG-1 files, as well as demuxing and sometimes repairing them. As a preparation and analysis tool used in conjunction with AviSynth or other tools it's invaluable for working with MPEG-2 sources.
This guide will cover how to open MPEG files, including DVD titlesets. It will also cover previewing, demuxing, and saving D2V projects for use by other programs. Before using DGIndex you may want to familiarize yourself with the basics of digital video, and specifically MPEG-2 encoding. You can find this information in our Digital Video Fundamentals guides.
