You should also not, though, that video is a relatively low resolution medium (roughly the equivalent of a 640x480 image). Documents (including PowerPoint pages) rarely are readably clear when you transfer them to video.
So if your goal is display a document for reading onscreen, it's probably not going to work. You're best off recreating the document in the titler.
I sort of figured it out on my own, no matter what resolution I used to scan or create the file, jpeg, psd etc. Once you insert the file into the video it comes out blurry. Then it dawned on me to use HD output which reflects the final image, of course the problem is still there that the size of a document will cause problems. So what I'm going to do is use portions of the document to limit the image blur. Thank you for the suggestion of using the Titler, in some conditions this can work but for others it might be too much work. Can you cust and past an entire document to a frame?
What is the format that retains the most sharpness for importing to PE or does it not matter just the settings?
TIFs and PSDs are cleaner than JPEGs.
However, as I said, video is only the equivalent of 640x480 pixels. You are not going to be able to produce a readable document as a graphic, except for maybe a few close-ups on the page.
Are you going to write a DVD, or a BluRay, or a file that is computer only?
If DVD, you are limited to the specification for that media, as Steve noted

The video will eventually be a HD You Tube video. Thanks for all the input
