Thank you so much for highlighting the significant points. Honestly, plagiarism avoidance strategies especially respected in this study. How can the researchers evidently prove the credibility of the videos? Do the researchers applying the YouTube videos as an instructional material or treatment successfully publish their articles? 

If something exists it can be used as evidence. 

If you happen to find a video which e.g. helps you to write better academic English, then you can acknowledge that in your Acknowledgements section. It does NOT appear in your References section, or the body of your thesis. 

Please give an example of where you have found credible medical research being talked about on YouTube, which is NOT available in the scientific literature?

Here is an example. Suppose a researcher is about to present the video file in his online classes before administering some academic writing tasks. He is also interested in analyzing the students' performance after watching the video file. Is there any publication rule for accepting or rejecting the articles in which such videos presented as pedagogical instruments? Anyhow, in this situation, in addition to the in-text citations, the references likewise have to appear in the reference list.

Ok. So the educational video is your intervention, which is supposed to produce some improvement in the integrity of writing of those students you expose to the video. How can another researcher duplicate your research without knowing which video you used? So you have to reference it in your research report and the general remark of your librarian is false. 

Thank you again. However, as you know, not all the videos publishing on YouTube are reliable resources. In fact, the characteristics candidating the videos for intervention requires careful attention. Whether or not, administering untrustworthy resources might result in article rejection!  

Dear Moohebat,

Similarly citing  websites, your question remind me  years ago asking about citing website in scientific research.  if  really something important , official or a surgical operation, or analyzing runners videos as to do optimal performance is acceptable.  I have cited this video in my work for first time in the journal of Visualized Experiments.

Thank you all. The attached link also shows the effectiveness of web 2.0 technology, and particularly the YouTube videos, on teaching and learning progression.
