[Air-L] About classification of short-length videos

[Xanat Meza]

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,
