24 is close to 25, when comparing to 12, 13 and 15.

I was saying that the 24Mbps mentioned was "close to Mini-DV and
HDV", which is 25Mbps. Which is also indicated by the second clause
of my sentence, below, you so cleverly dissected.

Kinda my point. But if and when such cameras are available,
AVCHD at 24Mbps., they would offer a very good format;
as "jerry" points out.
I've been playing with AVC and it has a much greater potential
than most see, especially in the seldom addressed HD
(High Profile-High level) formats. Most people are only seeing
H264 as something for their i-Pod or cellphone.
Personally, I think a 3CCD, harddrive and SD media, 24Mbps,
720p, AVCHD camera at a decent price point would be a hot
seller, and a great buy. The tech. is there, the codec and the
editing software pose no problems. Who knows the extra
4Mbps might solve most of the "problem" with HDV.
Luck;
Ken
