TOPIC This article explains why the video window of Apple Video player may appear as a blank or solid-colored screen on Power Macintosh G3 computers, and how to avoid this situation. DISCUSSION When there is insufficient VRAM to display video in the video window, Apple Video Player will default to a blank or solid-colored screen. Depending upon how much VRAM is installed, the resolution and bit-depth at which this will occur will vary. For example, on a stock Power Macintosh G3 with the base 2 MB VRAM configuration, any resolution 800 x 600 or higher will cause the video window to turn blue if the system is configured to display millions of colors. Lowering the bit-depth and/or resolution will correct. Therefore a 640 x 480 at 24-bit color configuration would be possible and not result in a blue/green screen. It may be useful to keep in mind that some video codecs, such as the Apple Video codec that Apple Video Player is designed to use (as opposed to Cinepak or Component video, for example), only saves video information at 16-bit color (thousands of colors) anyway. For the vast majority of video capture applications, 16-bit color is all that is needed and is indistinguishable to the eye from 24-bit color in this context. |
