Unable to find video preset options when exporting audio file for youtube video

I have a music track (no video) and I am exporting it as a video file to upload to youtube.  Previously, I was able to select from a variety of stock video presets to accompany my audio file, they included an animated vinyl turntable, an undersea animated fly through and several other animated video presets.  I can no longer find these.  It only exports as a black video with the audio.  I've tried every type of file type etc, and nothing brings back these video presets.  Where are the found?  They are not in any of the export areas, although they were when I tried several months ago but I can no longer find them.  Help!
