[Graeme Nattress] "HDCAM uses 440mbitspersecond"
That's quite a nice high data rate, especially for MPG4. The samples I have seen are the samples really to demo the concept of HD with MPG4 at low data rates (like 8Mbps), and from what I have seen that is just too much compression even for MPG4.

[Graeme Nattress] "A 50mbits MPEG2 for HD acquisition would make total sense, but I'd still want to edit it uncompressed. "
Can't argue with that, but I guess one of the the idea of 25Mbps was not just for compatibility with existing DV transports etc but also to seperate the HDV market from broadcast markets without killing it before it even starts by making it too low a bit rate altogether. Otherwise why wouldn't 720p use the full 25Mbps it has available to it?
