Video Save Options |
This dialog is displayed when you select Video for Windows (.avi) from the Save as type list on the Save As dialog and click the Save button. Use this dialog to select which video streams you want to save and edit the title, language, and priority of the saved streams.
Select a check box to save a stream. Clear a check box to exclude a stream from the .avi file. The black diamond next to each check box indicates currently opened streams.
Click on the Expand button
to display additional information about a stream.
Right-click a field name and choose Edit from the shortcut menu to modify a setting.
Click the Collapse
button
to hide additional information.
Select the Save audio to new stream check box to add a new audio stream that contains the audio currently open in Sound Forge.
Choose a preset from the Re-size video frames to drop-down list to adjust the size of the video, or choose Custom to specify a custom frame size in the New width and New height boxes.
This dialog is displayed when you click the OK button on the Video Save Options dialog.
To adjust compression for a stream, choose a stream from the Choose a stream drop-down list and click the Options button. The Sound Selection dialog is displayed when you choose an audio stream, and the Video Compression dialog is displayed when you choose a video stream.

Name |
Choose a preset from the drop-down list, or click the Save As button to save the current settings. |
Save As |
Click to save the current settings. |
Remove |
Click to delete the preset selected in the Name drop-down list. |
Format |
Choose a sample format from the drop-down list. Sound files are most often saved in the PCM format. However, other formats are often used for compression purposes. If you have the Microsoft Audio Compression Manager (ACM) installed, you can save files in a variety of compressed formats including the Microsoft ADPCM format. |
Attributes |
Choose a set of file attributes from the drop-down list to specify the sample rate, bit-depth, and whether the file is stereo/mono.

Compressor |
Select a compression format from any of the installed AVI compression schemes. Compression formats are available from different vendors (not from Sonic Foundry), and are also included with Windows. If the file is already compressed, you should select No Recompression. This will be faster and will also avoid the loss of quality inherent in most recompression. |
Compression quality |
Compression quality determines the final output quality. Usually, higher quality (close to 100) means less compression and fewer visual artifacts. |
Key frames every |
Some compression formats are based on key frames (sometimes called temporal compression). A key frame is a frame that is usually less compressed. Compressed frames that follow a key frame are smaller but slower to draw. This option is only relevant to video streams. A high number of key frames increases quality, but decreases compression. Also, if the number of key frames is very low, it will takes a long time to perform decompression when drawing the video strip or moving randomly through the file. |
Data rate |
Data rate determines the data rate that will be required to play the compressed stream in real time. Lower data rates are less demanding on computer systems than higher rates. If the data rate is too high for a certain computer (usually because of a bottleneck such as a slow CD-ROM, network, or hard drive) the quality begins to suffer and glitching can occur. |
Configure |
Click this button to set more detailed configuration parameters specific to the compression scheme being used. Not all compressors provide this option. |

Select the Interleave frames check box to interleave audio and video streams. Interleaving improves playback performance when using storage devices that are more efficient at providing data sequentially (such as CD-ROM discs). The Frames value indicates the interval between video and audio segments. The default is 1 for CD-ROMs, but can be increased for faster media.
