Chapter 19. Movies on CD-ROM and Kiosk > Preparing Movies for CD-ROM and Kiosk

Preparing Movies for CD-ROM and Kiosk

As with Web video, the most important thing you need to do to prepare your movies for CD-ROM or kiosk playback is ensure that their data rates are sufficiently low.

Because CD-ROM and kiosk video don’t have the same bandwidth constraints as the Web, you generally don’t need data rates anywhere near as low as those required for Web playback. For 4x CD-ROM (the low end of what’s commonly available), the data-transfer speed is 600 kilobytes per second. Movie data rates can approach 400 kilobytes per second—tens to hundreds of times the practical data rates for streaming Web video. Hard disks, on which you may store video for kiosks, can transfer data at multiple megabytes per second.
