Grainy still shots after rendering

I have Sony Vegas Pro 9 which does a nice job once you get the hang of it. The AVCHD video and sound are fine but my digital still shots are very grainy in the finished video. The original files are perfect played directly from the camera or from a burned data disc but once they are processed into a slide show they look terrible. Any suggestions out there. Jim

Hi.

You haven't provided a great deal of info about formats you're using/ rendering to, so it makes it a bit hard. Assume you're filming in HD (1920 X 1080 interlaced?) and then rendering to what? I'd be interested to know if you are rendering to a smaller format (e.g mpeg 2 for DVD) which obviously requires video and stills to be resized, which can cause quality degradation issues. What size are your still images. If you are shooting high res still photos they are likely to be considerably larger size than 1920X 1080 and resizing the stills in a graphics program (rather than relying on Vegas to do this) might help considerably (I prefer .png format and Vegas seems to handle these well).

Others here are way more experienced and knowledgeable than me, but this is an approach that has improved resultant stills for me.

Agree with Duncan, we need to see what you're talking about.
It's not uncommon for people to use the word "grain" when they mean something else. In fact grain simply doesn't exist in images from a DSC, only film has grain.
Digital can have noise, it could be compression artifacts, it could be aliasing.
Rip a still or two from the "slide show" for us to see and then someone might have a shot at figuring is what is going wrong.
