Why is my movie preview choppy, jerky, or stuttering?

The performance of the real time and full screen preview within Photo to Movie is dependent on many factors. Some suggestions for improving performance follow.

It is important to note that exporting the movie from Photo to Movie will produce a perfect movie every time, independent of the factors below. When you burn your movie to DVD it should play without any jerkiness or stuttering. Previews are only a preview of how your final movie will look.

Use smaller original photos. JPEG photos will perform better than TIFF photos. Your photos only need to be large enough such that the smallest key frame on that photo is at least as large as your export format frame size. For instance, if your export format is CD-ROM (see making your movie) then your export size is 320x240. If your smallest key frame is 80% the size of your photo then your photo size can be as small as 320x240 / 0.80 = 400x300. For optimimum quality your photo should be large enough that the smallest key frame is twice the size of the output resolution. In the example it would require an original photo of 800x600.

Make the editing window smaller. Using a smaller window will produce faster real time playback. Full screen preview, if available, will give the worst performance.

Edit your photo track first, without titles and without audio. Add the audio and titles after you're happy with the photo motion. Real time audio and title rendering can slow down the preview.

Quit other applications. Quitting other applications will stop them from using the processor and also free up additional memory.

Install more memory or use a faster computer. Photo to Movie can be a demanding application and more memory improves performance considerably.

To improve playback performance (Summary)

  1. Use smaller photos
  2. Decrease size of editing window
  3. Edit photo track without audio and titles first
  4. Quit other applications
  5. Use more memory or a faster computer
