Could the YouTube video comments be provided with download link for the model used in the video or model which is an example of what the video demonstrates?
If not possible in YouTube, then a link below the video thumbnails found on “https://plusspec.com/pdb-xxxxx-tutorials/” webpages?
This way the user can examine the model while the video is running. Also, examine the model in Layout and the TAGs/Layer Manager, check out different scenes, other features, or use the model to recreate copy of it or experiment with changing different parameters and compare the results to the original.
