| Publishing You may want to prepare variations of one program or clip for several uses. For example, you may want to prepare low- and high- resolution versions of a program or clip, or create versions for broadcast television, CD-ROM distribution, and Web viewing. You apply compression to the final video so that a computer can play your program smoothly. However, the level of compression you apply depends on how the final video will be played back. For example: · If you create a program that will be played from the Timeline while recording directly on videotape, apply compression settings that preserve the most picture quality without dropping any frames.
· If you will be recording to videotape using the same video card you used for capturing video, you can use the same compressor you used for capturing.
· If you create a program that will be played back from a wide range of computers, such as from a retail CD-ROM title, apply compression settings that allow smooth playback on the least powerful computer you plan to support.
Exporting or Publishing The composite video that you've edited in the video editing program is not available as an independent video file until you export or publish it. After you export a video file, you can play it in other video playback or editing programs and move it to other disks or platforms. Before you export, make sure the Timeline is ready to output at the quality you require. For example, replace any offline files with high-resolution files suitable for final export. In addition, you can also specify a range of frames to export.
