Thanks, Bruno. I looked up the flash memory write speed. The newest high-speed devices are 2 m bytes/sec. sony-europe.com And at 1 m byte/sec for video, a 1 GB would be 1000 sec. So that's 17 minutes. A 4-GB would be 1 hour, with motion jpeg. Which could then be transferred to dvd, and the memory card reused. Thanks for info. I just wanted a way to compare flash memory with micro-drive (in compact flash format). I am wondering whether the next replacement for tape (in cam-corders) will be a rotating drive, or flash memory. Currently, the 1.8" drives hold 20GB and cost $160. What I was wondering was whether the data transfer advantage of the hard-drive was meaningful or not. According to your experience, it is not. ------------------- Regarding mpeg4, it doesn't seem applicapable to live recording. excerpt from this site: axis.com It’s important to note however, that most of the tools used to lower the bit-rate are relevant today only for non-real time applications. This is because some of the new tools need so much processing power that the total time for encoding and decoding (i.e. the latency) makes them impractical for applications other than studio movie encoding, animated movie encoding, and the like. In fact, most of the tools in MPEG-4 that can be used in a real time application are the same tools that are available in MPEG-1 and MPEG-2. ------------- Sarmad
