Standard Video Formats for DVD Playback
The following output profiles are intended to create files which can be burned to a new DVD using a DVD authoring program, to play on DVD players:
- MPEG 2 DVD PAL
- MPEG 2 DVD NTSC
This help topic explains the settings for these profiles.
DVD files are saved using MPEG 2 video compression, with MPEG 1 layer 2 (MP2) audio compression. MPEG 2 files are given the extension .VOB when intended for use on a DVD.
NTSC and PAL
There are two major standards for DVDs which are used in different countries. The United States and Japan use NTSC (National Television Standards Committee) and PAL (Phase Alternating Line) is used by European countries and China. Most DVD players will only play discs made using the standard for their own country. Select the correct DVD format for the country of your audience.
Settings
Both these file formats have the same settings:
Video Settings
Frame Rate
The frame rate will be automatically set. This is part of the NTSC and PAL standards and cannot be changed.
Bitrate
The Bitrate is the amount of information that is stored in the file to represent each second of video. If you set a bitrate of 2000 Kbps, a 10 second video file will contain 20,000 bits of information about video. (There will also be audio information.) The higher the bitrate, the higher the quality of the video, but also the larger the size of the file. Generally, smaller dimensions will allow you to use a lower bitrate and still have a good quality picture. Typically a DVD's bitrate is in the range of 5000-8000 Kbps. Using lower bitrates will noticeably lower the video quality.
Dimensions
The default dimensions shown are the standard for your region. You can lower the dimensions, which will reduce video quality. If you would like to put very large amounts of video on a single DVD, you may wish to lower both the Dimensions and Bitrate..
Audio Settings
Frequency
Audio Frequency is the number of times per second that the audio signal can be adjusted.
Channels
Select Mono to include only one sound channel with your AVI file, and Stereo to include channels for both left and right speakers. Using Stereo produces slightly larger files.
Custom Profiles
If you expect to use the same modified DVD settings again, press Save Profile. This will create a Custom Profile which you can use in the future to quickly select the same options again.
