Poor resolution rendering to MPEG 1

Has anyone got any experience in rendering to Quick Time? I've been trying to improve the clarity of jpeg graphics (taken from powerpoint slides), but can't seem to get really crisp, clear video from them...resolution is very fuzzy and blurry. A friend suggested that perhaps MPEG 1 wasn't robust enough to support really detailed jpegs, but MPEG 2 leaves me with a file too large to burn to a CD. Is Quick Time a potential solution to my resolution problem?

JPEG is a poor format to work with as too much data has been lost in the initial compression. Going back to the ppt files and saving in something like tif might help.

To make jpeg graphics sharper in your rendered movies, it helps to do the following prior to rendering:

With your jpeg picture on the timeline and showing in the preview window, right-click on it. A window will appear; click 'Display at Project Size.' Your picture will pop up larger in the preview window. After you render, it will now be less blurry.

I'm not familiar with Quicktime so can't say how that video would turn out. Also, mgeg1 files will look good viewed in a small window but will be fuzzy at full-screen size. Nevertheless the jpegs should improve with the above procedure. I hope I've understood your question correctly and that this works for you.

blakeh: most of the quality depends on the bitrate you use for encoding. What are your encode settings? If you're using the standard VCD template then the mpeg file's resolution will also only be 352x240. Can you tell us what render settings you're using for mpeg 1 and mpeg 2? We can give you some suggestings for improving it.

Also, what is your final destination for the files? Are you planning on having people play the disc on a set-top DVD player? Or are you intending for people to play them in something like MediaPlayer on their computers?

Chienworks: I'm just using the standard template for Mpeg-1, although I've tried the VCD PAL setting, as well. I'm trying to create a CD with a video file, and consistently get either poor resolution or the file won't run in WMP due to an unknown file type or a codec error. Can you advise me? How do I improve my resolution in MPEG-1 (I've found that in some cases, MPEG-2 is too big for a CD)?

You're never going to get "crisp" videos out of VCD -- it's just not going to happen. It's like trying to get Roseann Barr to look like Brittany Spears.
