What you say is obvious.

However, at this price point, the only benchmark this little camcorder needs to achieve is "acceptable" 720/30p video.

If it does that, then it's probably going to sell.

Nobody expects the Sanyo to perform as well as the 1080i camcorders by the major manufacturers.

Guess what?

Many high definition TVs can't display 1080i resolution anyway.

This might be a worthwhile camcorder for the home enthusiast who has a less expensive high definition screen that only has enough resolution to show 720p.

I don't think anybody expects to do pro-level production with this little device.

On the other hand, I've seen work produced by some self-proclaimed "experts" who have the latest and the greatest tools and their work is so bad -- bad writing, bad execution -- that it could easily be stomped by truly talented directors, writers, shooters using nothing better than a Sanyo for acquisition.

The reviews weren't all that accurate; the model went to market with significant flaws that Sanyo never corrected.
At least this one might be what the HD1 should have been. If they had h264 at 9mb/s for the HD2 it might be better, but seriously, 30/60fps at 18 Mb/s would be nice, and nobody has to use it unless they want to.

Agree 100%.

It will be interesting to see how the Ambarella-driven SAMSUNG camcorder -- to be announced in the summer -- will perform in this regard.

Warning, even 60fps VGA mode is gone, poor sports crowd.

Notice it is missing, this is sad, now there is no 60fps mode for action scenes.

http://www.sanyodigital.com/video_ca...fications.html

Another warning, it looks like 720p will not divide evenly into the sensor resolution, I wonder if this may produce some interpolation problems as things move in front of the camera. Hmm, hold it, an bayer pattern has a diagonal stripe of green, and another of the red/blue stripe, this could produce and imbalance and stepping on diagonals in one direction if interpolation was not done sufficiently.

The good news, is that they have finally learned to put in a full width SD mode, 720*480 at 3.5mb/s.

They should have made an 720 60fps SD mode and retained the 60fps VGA mode at least. If they could have had 9mb/s version of all the SD modes, you could have such a rush on this camera by people for it's SD quality.

Good points.

Thanks for pointing that out about the 720 x 480 for SD; at first, I didn't notice that change.

Completely agree + HD/SD 25fps. I can´t understand the lack of a 25p mode for European models. This would have some advantages, like bitrate efficiency, higher exposition time ( better light capture ), near 24fps cinelook,..., and a lot of market in Pal countries.
Please, Mr Sanyo... 25fps... ;-)

Who is the first one to find an MP4 file on the
net one can download to check its quality ?

Does anybody know, where we can download such a
demo movie, which was shot with the HD2 ?

Many thanks in advance.

Regards, Stefan.

I am glad to hear that the 75% increase in low light performance, to 6 and 12 lux. Maybe this is an indication they have increased signal to noise ratio, and got rid of that fine noise during the day, along with less noise in low light. If this is true we may have much better compression performance. n 6 lux is close to the maximum 5 lux I would like. But with an low bit rate codec I would prefer 3 lux or less, and at least 48db S/N (preferably higher, enough to give you 100% noise free at 5 lux).

Sanyo put the HD2 in the japanese website:
http://www.sanyo-dsc.com/products/li...hd2/index.html

Also they have a comparision shot between HD1 an d HD2 in low light conditions:
http://www.sanyo-dsc.com/products/li...hd2/movie.html
looks good.

Maybe someone that speaks Japanese can help us find more info....I tried to find some demo clips like they had with the HD1A but couldn't.

Ah, yeah, *cough* I'd say something like this *looks for japanese dictionary*:

"It evolved the high-speed image processing LSI of hi-vision correspondence to a greater extent “platinum engine II” new development. With the improvement of noise reduction technology, at the time and the like of the evening it reached the point where it can photograph cleanly even with the scene which cannot guarantee the sufficient light intensity. Furthermore if “the High Sensitivity” button is pushed, brightness of the former ratio largest approximately 2 time *2, actualizing lowest subject luminous intensity 7 lux. Furthermore it became strong in dark place photographing.

*1 At the time of High Sensitivity mode.
*2 DMX-HD1A: Comparison with the lamp mode."

Should I understand that they are comparing the High Sensitivity mode of the HD2 with the HD1 with Flash??

I originally thought that Canon HV20 would be the contender to HD2, but the real punch seems to be coming from the other side of Canon.

http://www.dpreview.com/news/0702/07022203canontx1.asp

Canon powershot TX1. 7.1MP still, 720p 30fps video in 'Motion JPEG avi'!!! (Downside is that 4GB card holds only 13min video)
10x zoom with optical stabilization, plus many more Powershot features like face detection. And most importantly, $500 price tag.

I'd love to see the first hand review of this camera and the actual AVI sample, but with $500, which is about the cheapest HD1a price, this boy can steal the crown of 720p palmcorder from Xacti HDs.

Competition is good for consumers, in most cases ;)
