I have been analysing the HD1000 footage here:

http://forums.steves-digicams.com/fo...96&forum_id=27

And I decided to download some new A-HD footage and it seems to handle water rendering much better, but the problem is the Sanyo water footage is nowhere near as turbulent as the Aiptek one to judge:

http://www.skyhighsports.com/Aiptek/Aiptek.zip

One thing I can say is that the pixels seem to get bigger in the stills I could manage to extract from the Aiptek footage (which means they are sacrificing spatial resolution to maintain shape, but the turbulence is so much there does appear much blocking. But this looks better, and less turbulent water looks better.

I also noticed an lack of the diagonal interpolation problem that exists on the HD1 and GO-HD.

The Aiptek uses the Ambarella codec chip (by reports) and they aim at main and high H264 profiles, with an emphasis on quality at low data rates. I imagine it might be better than the Sanyo's, not that the Aiptek is any better overall than an HD2. Still obvious that the Aiptek needs 9Mb/s+ for 30fps for smooth image.


What has anybody else found, does anybody have both cameras do an comparison?

I have several downloads loaded to play things, and still can't get 1080i to work sufficiently. Power DVD works well, Media Player classic, and VLC (Gnome the "superior" player just crashes most of the time, but I think it worked better on the mt2 files). But I have several codec packs loaded, so i don't know which is causing ti to work at all. The mt2 files are trans-codes from H264 to HDV, probably because of the 1080i problem. See if any of this helps.
