First report on new AVCHD camcorders - details & pics
HDR-UX1 and HDR-SR1 - Sony Unveils AVCHD Camcorders - News, Guides and Tips - Consumer Camcorders - Camcorderinfo.com
Camcorderinfo is the first source I've found with details on the first AVCHD camcorders:
-HDR-UX1 and HDR-SR1 are the first two models (see linked article above for pic of the UX1)
-records to 8cm rewriteable DVD
-HDR-UX1 due September, $1400 MSRP
-records to dual layer discs, 1 hour recording time - 1.4 GB is normal 8cm DVD capacity, so if 2.8 GB capacity for dual layer, then 1 hour is recording at 6.3 megabits (815 kilobytes/sec or so)
-HDR-SR1 is hard drive based, $1500 MSRP, September as well
-in "long play" up to 10 hours recording time (implies lower bitrate) - but what's the drive capacity? Built in drive? Replaceable?
-CMOS sensor based
-HDR-UX1 and HDR-SR1 AVCHD Camcorders - The Digital Video Information Network is a thread on the new cameras, and includes a link to a folder of images of the cameras, which are clearly straight consumer cameras.
-Panasonic will have an AVCHD camcorder later this year
Mike's Analysis: My ultimate takeaway - at this point in time, this is a CONSUMER format. While the specs include 24p and higher bitrate support, none of that is happening at this point in time. The other big issue - hello, how/where are you going to edit this format? Much like the other DVD recording cameras that record MPEG-2 to 8cm DVDs, there's no clear and easy path to edit this stuff. At this time, Adobe is the only of the Big Three NLEs to take interest in the format publicly/formally - Avid and Apple haven't officially signed up yet.
So I say it'll take several things before I'd consider using this format for anything even remotely serious:
1.) Much better quality cameras than what has been announced to date - better chips, glass, controls, etc.
2.) Higher bitrates, almost certainly recording to hard drives or solid state memory, for better quality video
3.) Native NLE support - there's ZERO native NLE support at this time as far as I can tell (anyone feel free to correct me)
...and even when native NLE comes, H.264 is a very efficient but very processor intensive format - you'll need a FAST, RECENT, POWERFUL computer to have enough huevos to edit this stuff in real time.
So interesting, but not for a while yet.
Also, I've seen no mention of 24p support for these cameras (although the format allows it) - so indie moviemakers, stay away from these cameras!

Comments:
whats the native rez of these cams??? must be 720p, 1080i @ 6mbit/sec datarate vs. 25mbit w/ HDV codec is a HUGE diference in quality... but if they use 720p, then it could @ least be possible w/ good lighting to get presentable results....
smokeonit - It's Sony, so 1080i. It looks like they support both 1440x1080 and 1920x1080, or record 1440x1080 for 1920x1080 playback - not perfectly clear from the page I looked at. I'm betting 1440x1080.
Keep in mind, H.264 is a much more efficient codec than MPEG-2 (compare the rates used for both codecs used in high def DVDs), so a straight bitrate to bitrate comparison is not possible.

I have had discussions with one of the h264 companies, and there seems to be h264 hardware assist due. Much more GPU acceleration of H264 is due. Processors are increasing performance, and the number of cores is to rise steeply. On the other side 5Ghz processors are planned sooner than latter, from IBM, and I forget where ever Intel or AMD (though AMD is partner with IBM). Apparently, there had been some problems in relation to this 5Ghz speed on the upcoming power PC processor, but I am uncertain as to wherever this knocks it on the head. Anyway, 2 and 4 core processors should become, relatively, cheap compared to today.
There was a recent Pana/Sony announcement of 1 hour in 4GB, and several hours in 30GB, but no cameras were mentioned etc. Which is around 9Mb/s, but 6Mb/s still possible as a base.
6Mb/s versus 25mb/s, I don't think will cut it. Scene changes (motion etc) can overwhelm the codecs bandwidth compared to 25mb/s, but it should be able to handle interlace better, from my remotest memory. I think format may allow a devision between the consumer and prosumer levels. I suspect they could have two consumer and two prosumer levels, if they wanted, but do not know what they plan. All I say is, 24mb/s please now. It may merely be waiting for bluray/bluray market saturation, before it hits 24mb/s.
Have seen the new Foveon chip specs, would hope that a 24mb/s AVCHD, or Cineform, 720p Foveon still camera would be available, but nobody has indicated such.

the other sony avchd cam "is" 24mbit/sec... thats definetly good news for lowlow budgeteers;-)
cheers

oh, and i hope the avchd cams are not "i"... the h264 until now has huge problems dealing with interlaced encoding...
Yes, but, do you trust Camcorderinfo to get it right, and not be taken away with hype. We will know soon:
