About creating a video file for CD-ROM playback
When you create a video file to be played from a CD, you may need to specify export settings that take into account the wide range of hardware that your audience might be using, possibly including older single- or double-speed CD-ROM drives.
If your audience does use older CD-ROM drives, it becomes important to tune your exported video file for a low data rate. You can limit the data rate of your program simply by specifying it in Premiere, but if the video file still does not play well on your audience's computers, you may also want to make the following adjustments:
Lower the data rate and quality as far as you can without losing too much picture quality, if you specified a codec that lets you adjust data rate and quality. See About data rate and Exporting a video.Lower the frame rate as far as you can without making motion seem too jerky. Start at 15 frames per second. See Exporting a video.Lower the color depth to 256 colors. In addition to lowering the data rate, this may improve picture quality of video on a system or in presentation software that can display only 256 colors (8-bit color). See Exporting a video.Crop the picture for optimum viewing at a small size, reduce video noise to enhance compression, or adjust gamma for the target monitor, using the Special Processing panel in the Export Settings dialog box. See Exporting a video.Choose a file type and codec appropriate for the target audience. For example, for a cross-platform CD-ROM, you might specify a QuickTime codec. Choose a codec designed for low data rates, such as Indeo, Cinepak, or Sorenson Video.Choose File > Export Timeline > Save for Web, and select the AVI CD-ROM or QuickTime CD-ROM setting. Both of these settings automatically compress and save the file with the optimal settings for playback from a CD.
