    Hello there,

    Im planning to get a Sony Webbie mini-camcorder and a Canon HF-S10 for an upcoming trip this May/June. The Canon as the main camera and the Sony will be used by others just to mess around with.

    I noticed that the resolution on the Sony Webbie is 1440x1080. Upon doing research i read that the camcorders with the 1440x1080 resolution have rectangular pixels as opposed to conventional square pixels and therefore outputs video equivalent to 1980x1080. Is this correct? Or will i get a stretched (wrong aspect) look when i edit the two cameras videos together... assuming i can edit both cameras footage together in iMovie HD or '09.

    Thanks

    ...And any other helpful information would be appreciated.

    The pixels are still square... :confused:

    The difference is that 1440x1080 produces a picture with a 4:3 aspect ratio while 1920x1080 is a widescreen picture (16:9).

    The Canon also records in 1440x1080 in it's lower quality modes.

    The pixels are rectangular and when played back in software the knows how to properly display the pixels the image will displayed as 1920x1080.

    Do you know what you're talking about? HDV has a pixel aspect ratio of 1.33 making for a rectangular pixel.

    OK this is basically the information i was looking for. As long as the videos finaly output will display at 1980x1080 then im cool.

    Did you see the... :confused: I guess not. Sorry for the ill-informed post.

    So 1440x1080 displays the same as 1920x1080? That is news to me and bizarre. Hmm.

    It will display the "same" in that it will end up the proper aspect ratio, even though the ratio between the two is not then same, thus the rectangular pixel.
    It's the same reason 720x480 on a SD TV is 4:3 and 640x480 is 4:3 on a computer monitor, different pixel aspect ratios. The 720x480 frame is indeed higher resolution. Same thing with the 1920x1080 frame being higher than 1440x1080. The odd size is due in part to try to keep the HDV spec able to stay within DV video data rates ( 25Mbit )

    when you send your 1440x1080 to compressor and you do an output, you have to make sure you set it to display as a square pixel or it will look skewed after compression.
