By navigating to Settings > Thumbnails, you can specify a thumbnail image for each video that has been placed within your digital publication.
This thumbnail will appear before you play the video, assuming your video isn't set to auto-play.
Note - the thumbnails must be uploaded to the publication directly, not the group folder
To select a thumbnail, first navigate to the Files section and upload a .PNG or .JPEG image of any size or dimensions using the upload facility. Special usage should be set to None.
Next, navigate to the Settings tab, then Thumbnails.
The uploaded file(s) will appear in the drop down menu next to the relevant video(s) you have uploaded - simply select the image from the drop down menu and hit Submit to save the changes.
Remember to Regenerate your preview link to see the changes.
