Yes Guy the camera does have live video output that is the highest level component seen by the camera. It is 4:2:2. So clearly it is before the encoder.
After the encoder it is 4:2:0 MPEG-2 19Mbps GOP-6 1280x720p.
The audio channels for this camera are 2. Once again there is this confusion between this and the larger 2/3″ CMOS camera which is likely to be 4 channels of higher data rate audio.
I see people post about 50Mbps this or that. Actually this isn’t an applicable comment. For years we have shown 25Mbps D-theater tapes next to the Hollywood D5-HD masters and no one has aver been able to point to a part of an image or even motion and say “see that”.
IMX is/was 50Mbps but that is I-frame bound so it isn’t effective MPEG2. I personally thought it not as good as DigiBeta. To use 50Mbps for a GOP MPEG2 would really be very much more than is needed. People confuse this with DV since DV compression is their only frame of reference. So they look at 25Mbps DV and say well then 50Mbps is much better. But MPEG doesn’t go like that. Different animal.
So we will see in a week. Interestingly enough, the product people seem to be in a very happy mood. They think they have a special product.

Nate, The music wasn’t my cup of tea but the work was very good.
The camera is interesting in its size and shape becasue when you hold it you end up putting your hand in the lens strap. Then when you put your eye to the viewfinder (LCD color not CRT B&W) you realize the camera is now sitting perfectly fine on your shoulder. The round pad is on the side of your head.
It is okay on the shoulder because its short length makes your arm just about straight up close to your chest.
The difficulty in answering questions now is that any one detail could be changed at the last minute so it is now best to wait.
For example it appears the battery is a consumer battery for lower cost and ease of simple use. We think so many will be powered from AC on a tripod or truck.
The HDD may not be final by NAB.
Sorry Gary. It’s only a week.

I don’t know if our web site responds to inquiries outside the US. We are just the US subsidiary as you know.
Brian Rutz is the northwest District Sales Manager and he would have been sent the “contact” information from the initial inquiry. I hope no offense is taken. I thought the web site asks if you want to be contacted?
The progressive mention is to make clear that while some cameras are thought to have some progressive attributes, they may not really have a true progressive read out. Don’t I recall that some cameras have something called frame mode but what they actually do is double one field?
One thing I wonder about is the idea that from progressive we can “make” interlace. I don’t think I agree. Just becasue you take your progressive thirtieth of a second snap shot and make it odd and even fields that doesn’t mean moving items have the smoothness that interlaced video would have with its sixtieth of a second capture.
