Simple Answers re Scanning

I've seen probably ALL of the Vegas forum postings regarding scan resolution vs. print vs. screen, etc., etc. I do understand the differences and I don't want to revive that discussion. Many of experts seem to have quite diverse answers. There may be some exceptions, but I'm looking for a general answer that would work in most situations for the following: If you were scanning photos for one of your project that would be used with standard, widescreen HDV footage (1440 x 1080), and were going to be doing some moderate zooms/pans, can you provide simple answers to the following:

1. Scanner resolution setting (150, 300, 400, 600 ppi):
2. If you're going to be doing moderate zooming, and you were adjusting and saving the pixel dimensions in Photoshop (to include in a project with 1440x1080 HDV footage), you would set the photo pixel dimensions at:
3. You would save them in the following photo format:

Scanning resolution depends on the photos dimensions in inches. If you're doing an HDV project, assume the full square pixel HD dimensions of 1920x1080 and not 1440x1080. If you'd like to zoom in by 200%, you would want the image dimension to be twice the size of a 1920x1080 project, which would be 3840x2160.

If your picture is a 4x6, which is 6 inches wide by 4 inches high, then you would want to scan at at least 600dpi. A six-inch wide photo scanned at 600dpi will give you a scan that is 3600 pixels wide by 2400 pixels high. (6x600=3600 and 4x600=2400) If it's an 8x10 photo, then 400dpi would work, 10x400=4000 and 8x400=3200.

It's pretty simple, divide 3840 by the longest dimension in inches and that will give you the minimum DPI at which to scan the photograph.

Save it as a .PNG which is the native format of Vegas.
