you cant do much with quicktime text tracks, and it hasnt been changed for a decade or more - but for some things it might work.Apple released QuickTime 1.5 for Mac OS in the latter part of 1992. This added the SuperMac-developed Cinepak vector-quantization video codec (initially known as Compact Video), which managed the previously unheard-of feat of playing back video at 320×240 resolution at 30 frames per second on a 25 MHz 68040 CPU. It also added text tracks, which allowed for things like captioning, lyrics, etc., at very little addition to the size of a movie.
