Ausdauer and Bruno, Thank you for welcoming me here. There is a quantity that is obscured by the term VGA. Which is the color depth and CCD capture speed. I think plain vga is only 256 colors. First I was puzzled why a camera such as the PENTAX OPTIO, can capture 3 megapixles, but record continuous video at only VGA 640x480. I'll agree/concede that the flash memory speed is NOT the problem. By the way (Ausdauer), I think the 20 MB/Sec is bits per sec not bytes. But I may have to back away from that assertion, too. For now I'll go with bits. Still, that is fast enough for video. But we should find out why digital video is limited to VGA, when obviously the CCD can capture 10x that amount. It is either because the maker of the camera decided to limit our ability to use up flash memory (by limiting the capture pixels). Or, the CCD cannot CAPTURE all the megapixels at the frame rate. Or the CCD cannot TRANSFER all those pixels at the frame rate. Or, the color depth cannot be captured or transferred at the required rate. From investment point of view, it is helpful to know if the video mass market is actually open to flash. And if there are hurdles, I wonder whether they are related to flash itself, or other issues with the capture device. I will try to see if any video camera maker has implemented flash storage on analog video camera. That would bypass the CCD capture issue. If that market opens up, it is likely to be multiples larger than the still camera market. Sarmad
