I've converted my free report into a powerpoint to upload to my blog and distribute to video sharing sites but the quality of the text is too poor to use. So I now have some questions and need a bit of help.

Does anyone have any tips on improving the quality of text in videos?

What is the best system to use for powerpoint to video... i've tried moviemaker and memoriesonweb and both times i've ended up with poor quality

Perhaps it's just the format i'm saving in ... what's best to use?

Any help greatly appreciated
