It's not as simple as that. DVCAM has a 50% higher linear speed, but everything else stays the same, all the speed increase does is give guard bands between the tracks to allow the possibility of insert editing on tape and better machine-machine compatibility.

To record the higher data rate to tape would require extra heads on an already small head drum. Possible, but likely to be expensive. Which is, I suspect, why the tape deck on the HVX200 was limited to 25Mbs and couldn't record DVCPro50 or DVCProHD.

I don't think so -- I'm confident that this is the final design, and there won't be any deviation to the form factor or its fundamental feature set. My basis for supposing this is the fact that the previous instances I'm aware of in which Canon has shown a non-working prototype (XL1, GL2 and XL H1), those occasions were very close to the actual introduction of production units (within weeks), with no physical change between prototypes and working models.

As David says above, this really wasn't feasible. DV tape transports are limited to 25Mbps (that's why HDV had that bit rate, in fact). There are Panasonic and Sony tape transports that can accommodate 50Mbps and higher, but they are prohibitively expensive and therefore obsolete for our purposes here.

Another thing I've wondered about on occasion, is how much benefit there really is in acquiring images at 10 bits of precision, when video is that highly compressed. (Acquiring at 8 bits of precision does not preclude intermediate rendering using 10 bits of precision in post.) Just the other day, I was questioning (in my mind) if there really is any practical benefit to the 50Mbps flavor of AVC-I using 10 bits of precision (50Mbps AVC-I being effectively even more highly compressed than long-GOP MPEG-2 at the same bitrate, on the whole, since AVC-I gains none of the image quality benefits of using interframe compression, which is quite significant with most typical footage).

MSRP: Once again, that info will be included in the official Canon press release announcing the camera, whenever it is issued. Until then, nobody knows for sure (and those who do are restricted by NDA). Of course, DV Info Net always reports official news as it happens, so stay tuned to this site.

So it looks like the possible official announcement of this camera(s) will be happening this coming Monday, February 8th in the UK at the British Academy of Film and Television Arts (BAFTA).

New Canon camera to be launched on 8 February - Pocket-lint

Are we excited yet or what? :)

I'll take the day off and get a bag of chips for the announcement.

That sounds more like it will be an announcement for a new DSLR with HD video capabilities.

A vDSLR with 4:2:2 50Mb/s Mpeg2.... that would be extremely interesting. Ahh the rumor mill at work.

Canon is going to make a camcorder that records 4:2:2 with MPEG-2 compression. That much we know. That doesn't mean they won't introduce more DSLRs with video capabilities, or that their new DSLRs will record 4:2:2 MPEG-2 encoded video (doesn't seem real likely). It is actually possible (more like incredibly likely) that Canon will introduce BOTH a camcorder and a new still cam in the same year! Remember, this is a pretty conservative company, so don't hold your breath waiting for them to make a camera that's an utterly huge departure from conventional. Sometimes speculation gets a bit carried away...

"Take a look at the photos in my article... "

I did, but that eyepiece looks a bit harsh to me, though i'm sure it's great for folks with square eyes. Meanwhile the body has the chain-saw look we've come to associate with the pricier XLHI changeable lens model.

Are these pictures supposed to be of the A1 update or the H1 update?

This is the XH replacement -- the XL will follow (we haven't seen it yet).

The latest version of the invite I've seen says "We are pleased to invite you to a Canon Consumer Imaging Event."

Does that sound like the announcement of a professional camcorder? If this was Sony I'd say no, as they wouldn't classify the camera(s) we've been discussing as a "consumer" camera, but I don't know if Canon has a "professional" imaging division.

Might this be the new Rebel and/or 60D?

I think what has people on the edge of their seat is that Vincent mentioned in the other thread to wait after the 8th and all will be revealed. This invite linked is on the 8th and immediately many think it's this event where the camera will be revealed. I heard from two people it can be a 4K projector so who knows till then.

Their video division falls under their Consumer Imaging Group.

In any case, the Final Cut Pro SuperMeet event is today and we'll know about this camera by tonight as Canon is showing the first US unveiling of it there.
