Dear Tim,
Thank you very much for your prompt and kind reply!

OK, you can check the issue yourself:
video-test1.bmp is a screen of my TX1-video of 1280x720 pixel. It looks quite soft:

After reducing the size of video-test1.bmp down to 848x480 pixel, you will get a sharper picture video-test2.bmp:

After resizing of video-test2.bmp up to 1280x720 pixel again, you will have an oversampled picture video-test12.bmp:
http://yfang.com/download/video-test12.bmp
You will see exactly the same (soft) picture as the original from TX1. This is a proof that TX1 doesn’t really produce a HD-video of 1280x720 pixel which should show more details like the 1280x720 pixel video of Panasonic Lumix DMC-LX2 (but only 15 fps).
It doesn’t surprise me very much that one cannot get a real HD-video with a camera in this price class. What bothers me most is that the faked HD-videos take more than doubled memory space as need (848x480=407040 pixel vs. 1280x720=921600 pixel).
I’d like to hear an explanation from Canon (Japan) for such a behavior.
Best regards,
Yang

Dear Sirs,
It turned out that your new camera PowerShot TX1 doesn't really have the
resolution of 1280x720 pixel as announced, but no more than 848x480
pixel. It is just a waste of space to save big oversampled video files:

Could you please give me an explanation for doing so?
