    Interesting.

    Myth 4 - AVCHD is always better than MJPEG!

    Result: Busted.

    It all comes down to taste, the AVCHD codec has noticeably more vertical resolution and shows virtually no moiré but MJPEG 2048x864 on the horizontal has a superior resolution (even though extinct) but the main difference is that it has a superior acuteness that is impossible to ignore and might suit some people better.

    Myth 3 - In Full HD, AVCHD is better than MJPEG!

    Result: Confirmed.

    Not much to say here really, the AVCHD codec has a very small resolution advantage horizontally but extracts noticeably more vertically.

    Myth 2 - MJPEG the bigger the better!

    Result: Busted.

    The best resolution all along is neither the biggest vertical resolution nor the biggest horizontal, but instead the "magical" 2048x864. The sharpness in this particular MJPEG mode is something that trashes all other resolutions that I've seen, in fact the image is so acute, that you'll have to watch out for moiré problems in textures in real life footage. This result extends from HD to VGA mode where 2048x864 is also the best resolution.
