Is your feature request related to a problem? Please describe.
Currently, the function adddatasetstovideolistandviceversa tries to add the video, assuming that its in the videos folder. If one has a folder in the "labeled-images" folder that does not have a corresponding video in the videos folder, DeepLabCut will not report it missing but instead print that it added the video.
Describe the solution you'd like
Add a print() statement to the function when found is False
