AVI (Video for Windows ) 89 AVI (Video for Windows) Video for Windows was Microsoft's first multimedia architecture designed for CD-ROM use. Although it can be used for professional video and progressive streaming, it has been discontinued by Microsoft and has been replaced by DirectShow and Windows Media. The AVI format is, however, still used by the DivX codec as a container format. Video for Windows files are usually called AVI files after the .avi file suffix specified by the file format. AVI files are primarily used for audio and video. Technically, the AVI format supports MIDI and text tracks, but these features are rarely used and are not supported by any available players. The AVI file format is limited in many ways and is generally only used when backwards compatibility is required. Required Components for AVI The components required to author and play AVI files are built into Windows. QuickTime can also play many popular types of AVI files on Mac OS and Windows. Additional codecs may be required for certain applications and may be added to your system as needed. Creating AVI Files To create AVI files, apply one of the Cleaner default AVI settings to the source file in the Batch window. You can also make your own AVI setting by selecting AVI in the Format pop-up menu of the Output tab in the Cleaner Settings window and then choosing the desired codec and processing parameters in the other tabs. Codecs Apple Cinepak and Apple None are used for video delivery. If you're creating an AVI file that will be used cross-platform, Cinepak is generally the best choice. On the audio side, IMA is the best choice. Interleaving AVI Files Video data is written to the disk in segments interleaved with audio data. You can specify the AVI interleave in the Output tab of the Settings window. Cleaner gives you the following interleaving options: •1 frame - Also called formal interleaving, this option is used for CD-ROM movies and interleaves the audio between every video frame. This option also pads the sections to 2 KB boundaries. •1/2 second or 1 second - These options are best for network or uncompressed files.

AVI (Video for Windows)
Video for Windows was Microsoft’s first multimedia architecture designed for CD-ROM use.
Although it can be used for professional video and progressive streaming, it has been
discontinued by Microsoft and has been replaced by DirectShow and Windows Media. The AVI
format is, however, still used by the DivX codec as a container format.
Video for Windows files are usually called AVI files after the .avi file suffix specified by the file
format. AVI files are primarily used for audio and video. Technically, the AVI format supports
MIDI and text tracks, but these features are rarely used and are not supported by any available
players. The AVI file format is limited in many ways and is generally only used when
backwards compatibility is required.
Required Components for AVI
The components required to author and play AVI files are built into Windows. QuickTime can
also play many popular types of AVI files on Mac OS and Windows. Additional codecs may be
required for certain applications and may be added to your system as needed.
Creating AVI Files
To create AVI files, apply one of the Cleaner default AVI settings to the source file in the Batch
window. You can also make your own AVI setting by selecting AVI in the Format pop-up menu
of the Output tab in the Cleaner Settings window and then choosing the desired codec and
processing parameters in the other tabs.
Codecs
Apple Cinepak and Apple None are used for video delivery.
If you’re creating an AVI file that will be used cross-platform, Cinepak is generally the best
choice. On the audio side, IMA is the best choice.
Interleaving AVI Files
Video data is written to the disk in segments interleaved with audio data.
You can specify the AVI interleave in the Output tab of the Settings window. Cleaner gives you
the following interleaving options:
1 frame
— Also called formal interleaving, this option is used for CD-ROM movies and
interleaves the audio between every video frame. This option also pads the sections to 2 KB
