Resolution of the XL1 CCD's?
 

Does anybody know how many pixels are in the XL1 CCD's?

I know there are about 272,000 pixels but what does that come out to in terms of image size?

I figured a SD signal that is 60i would have to have at least 480 lines of resolution or the fields would be messed up. This then leaves us with roughly 566 pixels for a 566 x 480 image.

566 x 480 = 271680 pixels

Does this seem right or does anybody have any detailed information on how the CCD's are built?

566 x 1.25 would equal roughly 708 which would explain the black bars on the side of the image from the XL1.

Per a Canon manual, the effectived imaging area of each CCD is 512x492 (250k pixels). Canon uses a horizontal pixel shift technique (commonly used in high end progessoinal gear as well) to obtain something around 750x492 pixel performance for "average" scenes, which nets to roughly 500 lines of horizontal resolutioin.

I believe the usable DV image size is about 704x480 pixels.

thank you very much for the info. I am trying an experiment to match 3D objects to XL1 footage by trying to render out with the same sort of path the XL1 uses to get its image.

If you render out great sharp CG at 720 x 480 and try to composite into an XL1 frame there will always be something a little odd unless you blur your CG a little bit. I am trying to see if I can get my renders to be close to the look of the XL1. This may be a waste of time but oh well I have time to kill since I am on vacation.
