SlideShowPro Director automatically creates preview images of videos after they're uploaded. These images are then used for navigation links and as video previews in slideshows when videos are setup to not auto-start. Director stores multiple preview images for each video (using random keyframes from the video), so you can always change video previews to a different image, or upload your own. If your server doesn't support the ffmpeg library, you'll always need to create your own.
Click on the "Content" sub-navigation link in the album containing your video. Next, double-click on the video you want to edit. In the video edit area will be the default video image under the "Video previews" header. Click on the "Large" image. A dialogue will appear asking you to either select an existing image from the album, or upload a new one. If you haven't uploaded an image yet, choose the latter.
When finished, the assigned image will be used for both the video's preview graphic and any place where a thumbnail is needed. If you need to assign a different image for the thumbnail version, click on the "Thumb" image, then repeat the same process.
After assignment, video preview images remain in the album as album content, but their appearance is set to "Inactive" so they don't appear as slideshow content.
Click on either the "Large" or "Thumb" image that has been assigned to a video. A dialogue will appear with an option to remove the assigned preview image. When clicked, the video preview will revert to its default image. You may also remove a preview image by editing the preview image itself, and clicking the "Remove" button contained therein.
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 video you wish to assign it to, and release. The image will then be removed from the album's content. When the video is loaded in SlideShowPro, the assigned image will be used.
