WORKING WITH AVI FILES

Sound Forge XP lets you work with Microsoft Audio and Video Interleave (AVI) files.

You can edit the audio tracks of a video with single frame accuracy.This section

covers:

• Opening an AVI File

• AVI Navigation

• Attaching a Video to a Sound File

• Saving an AVI file

• AVI Video Compression

• Editing Audio in AVI Files

OPENING AN AVI FILE

To open an AVI file, choose Open from the File menu and select Video for Windows

(*.avi) from the Files of type list.Then, double-click on the file you wish to open.

If the AVI file being opened in Sound Forge XP contains exactly one video

stream and one audio stream, it will open these streams automatically.

However, if no audio is present an audio stream will be created containing only

silence for the entire length of the video.

HANDLING MULTIPLE STREAMS

AVI files can contain more than one video or audio stream.A stream is not the

same as a track in a multi-track video or audio editor. Multiple streams are

most commonly used to contain different versions of a video or audio track.

For example, you could have an AVI file with one video stream and multiple

audio streams in different languages. An AVI player, such as Microsoft’s Media

Player, can detect which language version of Windows your computer is using

and automatically play the correct audio stream for that language.

If more than one stream exists, the Video Stream dialog will be displayed when

opening the file. In this dialog, you must select a video and audio stream to

open by using the Stream Selectors (black diamonds) to the left of each stream.

Once you’ve selected one of each, press OK.
