SD is NOT] 72dpi.

There is NO dpi associated with video.

Ignore dpi. It is completely meaningless in video.

SD is 787x576. HDV is either 1280x720 or 1920x1080. Resize your pictures appropriately for those frame sizes.

Don't forget to add extra resolution for pans and zooms. You should be able to zoom into a quarter frame, so you want to start with a picture that is twice as big as you would need if you weren't using motion.

Usually a photograph is taller than a widescreen video frame, so if you adjust for width, the height will be more than enough. With that in mind, an HD frame is 1920 pixels and an HDV frame is 1440. Multiply that by two and you get 3840 for HD or 2880 for HDV.

Thus if you batch run your photos through a resizing program that will give them a width of 2880 (the height will be more than you need), you'll be ready for your pans and zooms.

You don't want to use 1440 as the width for HDV. Use 1920. Photographs use square pixels. A 1440 wide photograph would only fill 2/3 of the width of the frame.

Yeah except that it's interlaced. The real vertical resolution is really only 540 x two fields. The sensors in a camera like the Z1 are square pixel as well and they are only 960 x 540 and nobody is complaining about that. Anyway, we're just talking about enough resolution to cover the maximum zoom.

Yes but there's 3 of those sensors that are offset. A DSC has only 1 sensor.

That sensor offset is what gives you the 1440 out of the 960 sensors. The point is, the maximum resolution out of an HDV camera like a Z1 is 1440 x 540. With that in mind, a square pixel image that is 1440 x 810 isn't bad.
