If you are using the "Thumbnails" Navigation Link Type or link preview pop-ups in SlideShowPro, you'll want a thumbnail image for your video. First, upload an image (if one isn't in Director already) to the album containing the video. Then in the "Content" area, click and hold on the image you want to use, drag it over the image area of the video you wish to assign it to, and release. The image you uploaded will be removed from your slideshow content, and will be associated with the video asset instead.
