Still image quality is inferior.

I want to use some still images in my video, but I can not get the quality of the still images to be as good as the video. The sharpness is lower. This means that when I play the resulting video there is a disturbing change in picture quality while the still image is displayed on the screen.
I have tried to resample the still image in PhotoImpact to various pixel sizes but I have not been able to get the original quality of the still image.
As I want to pan a little which image size is optimal.
I have saved my images as jpgs with 95%. My video is PAL.

Any ideas or suggestions would be most welcome!

Thanks

Where did you source the stills from?

The stills are coming from my Canon Digital Ixus 800 IS (Powershot Digital Elph 6.0 Mpixs). They look great printed on paper or in Photo Explorer/PhotoImpact.

Hi

I use 768px x 576px (minimum size) for my image sizes.

If I intend to use Pan and Zoom, some quality loss will be experienced when Zooming in.
To compensate I increase the pixel size to 1536 x 1152.

What size (pixels) images are you using?

I have tried various sizes between 2000 to 768px (width).

When you insert your pics to you get a quality that reflects the quality of your originals?

Hi

The quality of my inserted images are as good as the originals. (usually Jpeg at 768 x 576) No pan and zoom

Playback, as viewed on the preview screen may be a little slow depending on the amount of editing., but once rendered and burned to disc show very good.

This subject has been discussed many times. Some people, such as myself, never have to change the size of my pics. I just import them from my camera and they look great, even if I use Pan & Zoom. Maybe it's a hardware issue (graphics card?) since some have problems and some don't.

In File/Preferences, Edit tab, do you have the Resampling quality set to Best?

I never tested with the various settings there to see the difference but I always used Best and the Compression/Quality slider bar to 100 for rendering and like Black Lab used my pics straight out of my 8 Mpixels camera and the quality was always excellent, even with pan & zoom.

Just to confirm, my Resampling is set to Best, and I always set the Compression/Quality to 100.
