Hello everyone, I have been conducting research on social media based videos for a long time, but most of them have been in long format (10 minutes and more). This time it looks like we have many short-length videos. I read a paper a long time ago, about either Instagram or Tik-Tok videos, where they used a classification such as reply video, reaction video, commentary video, etc. Does anyone have a similar classification that we could use as reference? I am not talking about automatic classification here, so please keep that in mind. Regards, Xanat V.
