    Default Noobie question

    Just bought the Canon HV40 Hi Def Mini DV camcorder. When I go to capture the video in Sony Vegas Movie 9.0, why does it show on the properties that the video is 1440 X 1080? The cam camcorder is set to HDV. The tapes are HD MiniDV from Sony. Vista 64 Thanks for any feedback in advance. Rick

    A bit of Googling shows that is correct: The HV40 outputs HDV at 1440 x 1080i.
    My guess is you're looking at the spec on the Canon site which says pixel resolution is approx 2.07megapixels which equates to 1920 x 1080 (aka in some circles as "full HD"), right?

    Well, it appears that that is the resolution of the CMOS sensor - what it picks up rather than what it records.

    I am new at this. I though HD was by definition 1920 x 1080. So my HD Vaio computer laptop is stretching out the playback on full screen? Thanks so much for your help in this. Rick

    The manual says 1920 x 1080 but I guess I am reading it wrong like you say. thanks for the link

    Now that is odd. It really sounds like you've recorded at 4:3 OR you need to "tell" your playback software that the video is widescreen.
    How does it display on yout TV (direct from camera using HDMI)?

    BTW I don't entirely trust internet info. The link I gave looks like it knows what it is talking about but I couldn't find other links to back it up or deny it - so it's just possible that the info on that site is wrong.

    Maybe another HV20/30/40 user here can confirm.

    Chapman Photography, maybe??

    Hi
    Just to set things straight FULL HD is 1920x1080 but because it's interlaced video the file size becomes 1440x1080 because the horizontal pixels have an aspect ratio of 1.333 (1440x1.333 = 1920)

    It's much the same as PAL 4:3 video is 720x576 and PAL Widescreen Video is also 720x576 BUT the widescreen pixels have an aspect ratio of 1.77 so the TV stretches the picture width to fill the screen!!

    In HD the TV will stretch the picture from 1440 to 1920...that's the way they work with all widescreen video.


    Don't panic your video WILL be full 1920x1080 when played on a TV .. with any widescreen format you have to take the horizontal aspect ratio into consideration so get used to editing at 1440x1080 and watching at 1920x1080!!!

    Thank you for that answer. That does explain it all. This is the standard.

    If you use HDMI it will be 1920x1080 with 4:2:2 color space, and you have to record directly to your PC. So its true it is 1920 x 1080.

    1440x1080 with 4:2:0 is the limitation of Mini DV tape.

    I hope that clears up the confusion a little bit.
