Apparently Adobe video related products are slightly selective in what metadata they show or not. My experience with Prelude CS6 and Premiere Pro CS6 is that any kind of clip or memo text markers are not supported and do not show in any way.
I had this idea to roughly sync slideshows with memo text markers to the video of the presenter, but now I have to check timecodes separately in P2 Viewer and then add the slide transitions to appropriate spots in Premiere.
If there happens to be a better way to do this, please let us know.
