16:9 Widescreen DV capture (from Camcorder) - Proper Resize?

[Dali Lama]

Hi,

I think the title says it all. My Sony camcorder supports 16:9 aspect ratio recording. I used it and I loaded it into my computer as a DV file. However, once I process the video I am confused as to the proper way to crop and resize to get the square pixels.

Here is what I know:

For most video, the pixels are meant to be viewed as square. This means that on a monitor, a square pixel 640x480 should take up 640x480 pixels. The pixels in DV video, on the other hand, are taller than they are wide. However, when viewing a DV video on a monitor (a square pixel device), are pixels are displayed as square. This forces the DV pixels, which are supposed to be horizontally thin, to stretch out so they are square. The result is that the video is wider than it should be. To correct for this, the video must be shrunk horizontally through resizing. Thus, you resize a 720x480 DV video to ~654x480 to make it look correct on a square pixel monitor.

However, this does not mention 16:9 aspect ratio recordings. My DV file resolutions are still 720x480 NTSC.

Thanks for the help,

Dali

and Donald Graft (neuron2) has the "Smart resize filter" for VirtualDub that could help you :-) .

Probably you know all of this, but if not, maybe it helps.
