You may find that resolution is too high. The closer you get to the actual resolution the better.

Scaling down loses resolution, especially on text which has hard edges and becomes blocky.

e.g. If you're using 720 x nnn and the image is to be used full screen then 1440 should be the maximum width of the image.

First, read this old thread that has lots of good info on scanning for Vegas:

Scanner questions (for photographs)

In that thread, I gave a basic tutorial that explains dpi vs. pixels:

relationship between dpi and total pixels

Finally, you say you are scanning a brochure. This suggests, perhaps, that this is something that was printed using a traditional printing process. If so, the photographs in it will be composed of individual dots rather than continuous tone photographic particles. If so, these dots must be removed before you use the result in Vegas or you will have really nasty artifacts, especially if you us pan/crop to animate the photos. Some scanning software can "de-screen" these photos during scanning. The nomenclature used to describe the function may vary depending on your scanning software, but the intent is to merge the dots together. If your scanning software doesn't have this feature, then your photo editing software may have it. Also, you can use very, very small amounts of Gaussian Blur in your photo editing program. If you set this just right, the dots will disappear, but all the detail will be retained.

Hope that helps.

The most effective method i've found for dealing with screening is to scan at an extremely high resolution, such as 4800dpi, then resize/resample the picture in photo editing software much smaller. So, if i'm shooting for 300dpi i'll scan at 4800 then resize to 1/16 afterwards. That pretty much eliminates the screening completely while retaining a lot of detail.
