I have been reading in a japanese test report ( via online translator )
that the Canon HV20 can do the still capture to its SD card in realtime
without interrupting the video, but I don┬┤t know any other cam that
can do this...

I would really like to go with Canon HV20, cause it has so great features
and also the 24p Mode etc,
but I really want to get away from tapes and it is much too bulky
to carry it with me all the time.
The Aiptek HD or the Sanyo HD2 are so small,you can always carry them
with you and take HD video on the road...okay, not so extremly good
picture quality as the HV20, but good enough for my 1368x720p TFT
flatscreen... I guess...

The question is,should I go now with the Aiptek or
invest more money and get the HD2 ?

Also in about 3 or 4 months we willprobably see
many more compact SD chip camcorders based on these
new H264 chipsets, so buying now an expensive modell
will loose you more money, than to buy now a cheaper one
and get a second generation modell in a few months then...

It depends,what you want now or later..

Probably at the end of this year we will have Full HD
1920x1080p chip camcorders at the same price tag as the HD2
with great picture and movie quality !

One other question to the guys who already have the Aiptek HD:

Will during HD movie recording the video output be displayed through its
YUV output ?
So, if you are recording an HD movie and have your cam hooked up
to your flatscreen TFT via YUV outputs, will it show
the picture there also during recording ?

If yes, it could also get used to be captured by a better capture
card.
This of course only makes sense, if the YUV output is not after
the internal compression circuit, BUT BEFORE !

Then you could have a very good 4:2:2 or even 4:4:4
recording, if the capture card supports this and thus
have better color reproduction and less compression jaggies !

But of course you would need to take a notebook
or laptop with a YUV capture card always with you,
which makes not much sense for me, cause this camera
is designed for great portability...

But some folks could use it this way for more professional
work then..who do not need to carry it around much...

So if you have a minute time, please check that out.

Many thanks.

Regards, Stefan.

Hey Stefan. While I was playing back the video on my plasma using the camera to play the video via component cables, I could pan around the room with the camera and the image would show up on my plasma tv in realtime. Does this answer your question?

As some may not know the Aaiptek go is selling at costco.com for 250 free shipping

Hi Xphyle,
yes, that answered the question.

Now can you please compare the image quality
while
1. just panning around without recording
and
2.record the same panning and play it back

and then compare the image quality ?

Does the recorded movie image quality look a bit more
compressed than the unrecorded panning ?

You really have to go near your TFT set to see the difference !

Many thanks.

P.S. Are you going to upload today a few pictures from this cam ?
I am anxious to see the still picture quality in best 5MPixel resolution.

Yes, please post the pictures. I am also very curious.

And it would be great to have a picture taken in a low light room using the flash. I was wandering whether the autofocus is working under poor light conditions.

Thanks in advance.

Thanks for all this Xphyle.

When you say real time, their is no lag of an fraction of an second, or longer?

It is hard to test for compression comparing with an live image (one reason being that H264 has an de-blocking filter). In high/complex movement parts of the image becomes blocky, among other things. You can see it from an little distance, but up close is an lot easier.

It would be good if you could look at the live output, to see if problems like the jaggies, and diagonal block problem of the recorded footage are still there? Jaggies normally, refer to interpolation issues, where slanted edges (bright/high contrast the worse) take on an rough staircase look. The diagonal block problem is worse again, on the Sanyo HD1 macro blocks of multiple pixels appeared rotated, or something, sticks out even more, but only in diagonal edges in one direction.

I think, the problem for Sanyo, is they added so little to the camera, and frankly, and number of AVCHD cameras, and the Canon HV10, Canon HV20, are just better/better value for the money at a few hundred more on the street. But it is good Sanyo listened a little.

What is the physical dimension of the GO-HD? (I don't see that listed in the Aiptek website.) How does it compare to the Sanyo HD2, and the Canon TX1?

I assume the GO-HD has a standard tripod hole at the bottom?

Thanks.

It has a standard tripod hole at bottom. Hope it is possible to replace the battery and the SD card while the tripod is installed.

Go to www.aiptek.com and search for Go-HD. There's a link to the manual from the product page. Also, on the right side there's a link to "Comparison Chart" - then click "High Definition DVs". Here's some interesting tidbits:

According to the manual, battery life is 30min - ugh! That's why there's 2 battery packs I guess. Also, note above "Video Stabilization yes" and "Av - in" (Record AV from TV/VCR/DVD)". The video stabilization I'm guessing is software not optically based and may account for some video performance issues. I'm hoping "Av - in" is not a typo although I don't think I'll actually use this feature.

According to the manual, there doesn't appear to be any manual focus or 'lock focus' options. So when you're filming, you're depending upon the camera to do the focusing which as we've seen in some uploaded videos has problems. With the photo snapshot you can press the shutter half way, let camera focus, and press button all the way to take your shot - hopefully it's still in focus!!! There's a macro mode as well but still requires camera to focus.

Doesn't look like there's a fast sequential shot mode.

(I'm comparing these features to my Sanyo HD1a so I hope my expectations aren't too crushed once the Go-HD arrives.)

I haven't read anything about a lens cover.

But then the Aiptek is half the price of the Sanyo Hidef Cameras and so far the video quality doesn't look too bad considering this. Naturally there will be some compromises.

There are many things I am not happy about with my MPVR but when I consider it's a camera that costs $150, I can put up with them because the video quality is not that far from my Sanyo C40 which only came down to $200in recent months whereas the Aiptek started out as a $150camera.:G
