TMPG TMPGEnc: Encoding MPEG-2 for DVD

Chapter: DVD Authoring

Topic: Encoding for DVD

To make a DVD that is playable in home set-top players, all video content must be encoded to MPEG-2 within certain parameters. This guide covers how to encode MPEG- 2 video that is compliant with the DVD specification. While this guide focuses on using TMPGEnc to do the encoding, the general principles must be applied to any MPEG-2 encoder.

Encoding MPEG-1

Chapter: Distribution

Topic: Encoding Techniques

MPEG-1 is a very old compression standard and its quality has long been surpassed by more modern codecs. However, virtually any computer in use today can play back MPEG-1 files, which still makes it a good choice for web distribution, particularly if your audience is on multiple platforms with no control over media player type or generation.

General Compression Tips

Chapter: Distribution

Topic: Encoding Techniques

Choosing the right codec is important, but its not the only factor you should consider when compressing a video. There are many other areas that you can tweak to get better quality or smaller file sizes.

Using a Scan Converter

Chapter: Image Acquisition

Topic: Computer Screens

This guide is specific to the lab the author wrote it for, but most of the principles are the same for any scan coverter used to get computer screens to DV for editing and inclusion in video programming.

Making Titles and Graphics NTSC Compliant

Chapter: Titling

Topic: Quality

When making titles and graphics for video, one must make sure that they conform to the standards of NTSC video. NTSC is much more restrictive than what computers can show, so graphics that may look fine on your computer monitor may flicker or appear washed out on TV. On the other side, graphics that conform to NTSC standards may look dark and dull on a computer monitor. It is best to work within these standards and then test your graphics out on a TV to see how they’ll really look.
