Canon HV40 question

[hpharley90]

I just received my new HV40 and have read many threads about the HV20,HV30 and HV40 on this forum.
I'm playing around with it and saw that the dimension are 1440X1080 instead of 1920X1080.
Why is that?
I brought a small clip into Premiere Pro CS3 and that is when I noticed the dimensions.

Also when capturing with CS3 there is no preview in monitor during capture.Weird. I pause and then you see the clip in the monitor. As soon as I hit record some Asian writing appears in monitor during capture. It appears normal but I don't like it.
I then used HDVSplit and I like that tool better for capture. I am starting to learn to use new tools.
I am down converting in camera now but I want to try the HD on SD disc that I read here this afternoon.

Hi Richard,
The dimensions for HDV are 1440 x 1080 and will upconvert to 1920 x 1080 at export and the quality will be excellent. I think Paul or Bob can explain a little better why it is that way. All I know is that I capture with HDV split, it has a preview and can split by timecode, and then import that into Premiere 1080i 30 project. Everything from that point when exported can be 1920 x 1080 and still have the same great quality, not sure how that works but it does

I also recommend capturing with HDVSplit - many of us do.

Yup. That's what I use too.

Chuck is correct. The reason that the dimensions are 1440x1080 is that it is recorded on the tape in HDV format. The HDV specification supports 1440x1080 with a pixel aspect ratio of 1.33:1. Because of the larger pixel aspect ratio, the 1440x1080 image will display the same size as a 1920x1080 image (which has a pixel aspect ratio of 1:1). There will be a little lower horizontal resolution compared to 1920x1080, but the image quality will still be excellent.

The sensor in the camera is capable of 1920x1080, but to get it you would need to capture live, not recorded to tape, with the camera tethered to a computer using a HDMI connection to a Black Magic Intensity capture card. You would also need some large raid 0 disks to keep up with the transfer rate.

Thank you very much for the explanation guys.

Thanks Bob. I hooked the HDMI cable from camera to TV played a clip and all 1920x1080 pixels were lit up.
