Saving a Video for Windows (AVI) File |
Click anywhere in the data window to select it.
From the File menu, choose Save
As or click the Save
As button on the toolbar
to display the Save
As dialog.
Use the Save As dialog to specify a folder and file name.
Choose Video for Windows (*.avi) from the Save as type drop-down list.
Click the Save button. The Video Save Options dialog is displayed.
Adjust the settings on the Video Save Options Dialog as desired and click the OK button.
The Video Save Options dialog is displayed when you choose Video for Windows (*.avi) from the Save as type drop-down list and click the Save button on the Save As dialog.
Select a check box to save a stream, or clear a check box to exclude
a stream from the file. The black diamond
next to each check box indicates currently open
streams.
Click the Expand button
to display information about a stream.
Right-click a field name and choose Edit from the shortcut menu to modify a setting.
Click the Contract
button
to hide stream information.
The Video Save Options dialog is displayed when you choose Video for Windows (*.avi) from the Save as type drop-down list and click the Save button on the Save As dialog.
Select the Save audio to new stream check box to add a new audio stream that contains the audio currently open in Sound Forge.
The Video Save Options dialog is displayed when you choose Video for Windows (*.avi) from the Save as type drop-down list and click the Save button on the Save As dialog.
Choose a preset from the Resize 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.
Select the Create an OpenDML (AVI version 2.0) compatible file check box if you want to save your file as an OpenDML file. OpenDML files allow you to create files that are limited in size only by the format of your hard disk: 2GB using FAT32 or 4GB using NTFS.
The Compression Options 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.
On the Compression Options dialog, choose an audio stream from the Choose a stream drop-down list and click the Options button. The Sound Selection dialog is displayed.
Choose a preset from the Name drop-down list, or adjust the controls as needed:
a. Choose a sample format from the Format drop-down list.
b. Choose a setting from the Attributes drop-down list to specify the sample rate, bit-depth, and whether the file is stereo or mono.
When
you convert from mono to stereo, the data will be stored in both
channels. When converting from stereo to mono, the data from both
channels will be mixed to a single channel.
Click the Save As button if you want to save the current dialog settings in a new preset.
Click the OK button.
On the Compression Options dialog, choose a video stream from the Choose a stream drop-down list and click the Options button. The Video Compression dialog is displayed.
Choose a compression format from the Compressor drop-down list. 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 choose No Recompression . This will be faster and will also avoid the loss of quality inherent in most recompression.
The
following settings are not available for all compressors
Drag the Compression Quality slider to determine the final output quality. Higher quality settings (close to 100) produce less compression and fewer visual artifacts.
Select the Keyframe Every check box and specify the interval you want to use for creating keyframes in your file.
Some compression formats are based on keyframes (sometimes called temporal compression): keyframes contain all information required to display an image; frames between keyframes are called delta frames, and they contain only the information used to display change. Delta frames are considerably smaller than keyframes; however, the visual quality of delta frames is poor.
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.
Select the Data Rate check box and specify a bandwidth to determine 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.
Click the Configure button to set more detailed configuration parameters specific to the compression scheme being used. Not all compressors provide this option.
Click the OK button.
On the Compression Options dialog, select the Interleave frames check box to interleave audio and video streams.
The Frames value indicates the interval between video and audio segments. The default is 1 for CD-ROM drives, but can be increased for faster media.
