pan & zoom is not smooth

In the past, when I pan and zoom on JPG or TIF stills, I got a very smooth result. Really looked like the camera was panning and zooming. Recently, however, I have tried to pan and zoom on a JPG or a TIF of fairly high resolution and the result is a very jerky output. Sort of like the frame rate is 10 fps rather than 30 fps. Not at all acceptable.

Any suggestions?

Have you tried one of the old, working stills? What happens?

Is the problem in the rendered video or in the preview?

The problem appears in both the preview and in the rendered MPEG movie.

Did you try any of the same exact files that used to work? IanG's suggestion sounds like a good one to see if anything has changed in your setup.

the older pics work just fine. very smooth.

Couple thoughts/observations.

The new pic that will not smoothly pan and zoom is not a very high resolution image. Could that be part of the problem? I could make it a higher resolution JPG or TIF if we think that might help.

Another observation is that the new pic (the not smooth one) is full of sharp/distinct horizontal and vertical lines. Not smooth, rounded, blended, edges but very sharp lines. Could it be that MovieStudio has difficultly smoothly panning and zooming such distinct lines?

The Fast Video Resizing option is checked by default. I found that if I uncheck this item, the Pan & Zoom functions much better. It will increase the amount of time to rendor your video.

The old stills (any "photograph") works just fine. I am having the problem only with this one graphic. It is a "tree chart" that is generated in JPG, TIF & PDF (my choice) from a geneology program. Hence all the vertical and horizontal lines. This is the only "picture" that seems to be giving me trouble.

And yes, the lack of smoothness problem is not just in the MovieStudio preview but in the finished MPEG also.

If you haven't tried it already, I'd see what happens if you up the resolution as high as the program can go.

Alternately, you might consider printing it out, then using a scanner to capture into a higher-res image file.

What resolution were the "old" images that worked fine?

The old (good) stills were taken with a 2 megapixel and some with a 4 megapixel Canon digital camera.
