    The pixel aspect ratio (PAR) of HDV footage is 1 to 1.333.
    Each pixel is stretched 33% wider to fill the 1920x1080 display aspect ratio.
    This is the HDV standard.

    Confused me too until l understood this . . .

    Hey thanks for the info :)

    I'm not sure about the differences of Edius's prject settings of interlaced and progressive?

    Hmm, interesting! Well I am rather pleased with my V1E and how good it's crisp interlace artifact free progressive mode and it's beautiful 20x lens looks on my HDTV when connected to Edius via the NX hardware.

    To keep this on topic with Edius, if I may...

    Since the V1E's progressive frames are actually carried over 50i (progressive segmented frames), does anyone know what advantage there is to choosing the Edius 1440 x 1080P over 50i project preset (field order progressive) over the standard 1440 x 1080i (upper field first) preset?

    Seems to me there is no difference, I always see only great frames - which is fine by me but maybe there are other differences that in the camera footage, such as added titles or pips in motion animating a frame at a time instead of a field at a time? Only this is not certain in my mind and GV must have introduced this "1080P over 50i" for a specific reason.

    Interesting...it is there on Sony's web site. You have to hunt a little bit, but it is 960x1080. The key part of the reference to 1920x1080 is "internally process signals." The camera captures at 960x1080. Then, completely inside of the signal processing chip, the video is "interpolated" to 1920x1080 and "resolution converted" to 1440x1080. The conversion to 1440x1080 occurs before HDV compression, so the useable output from the camera is 1440x1080, not 1920x1080.

    Thankyou, thankyou, thankyou!

    It does matter to me, because I hate not knowing. And also, there are a few more camera's that have very similar features to the V1P for 1 - 2 thousand less. I imagined that if it did shoot 1920x1080 then that would justify the price, but now that that has been cleared up ...

    Oh, and I had the idea that HDV is always 1440x1080, but wasn't sure. Thanks again for clearing that up.

    I've been searching for the answer for like nearly 2 hours.

    I know it shoots 1080i, but what about the pixel shape and the vertical lines???

    The reason I am confused is because in sony's specs page there is a diagram which shows 1920x1080 and a line that says something like "....which internally process signals in the progressive domain at 1920 x 1080...." but nowhere does it say

    "record mode of 1920x1080"...

    Thanks heaps :)

    By the way, I've searched dvinfo and cant find the answer there...
    1080 HDV is always 1440x1080. That is the format spec. Some HDV camcorders have 1920x1080 image sensors. One thing that can make this useful (to some) at the lower end is the ability to pass 1920x1080 video through HDMI direct to disk. I suppose there could also be a claim that starting at 1920x1080 is better than 1440x1080 even where the recording format is 1440.

    Maybe the image sensor resolution is what's being referred to in the case of your HVR-V1P. Again, it can't be HDV recording.

    Does that have HDMI?

    I have the HVR V1E that is sold here in the UK, it records in 1440 x 1080 anamorphic (squished) format.

    Does this matter to you?
