What's the difference between short video and vlog?

The difference between short video and Vlog is that vlog video basically needs bloggers to appear, and bloggers need to introduce something to you or express something through narration and explanation. However, short video content is more content creation, and the meaning of "recording" is not strong, more like a unit drama, a "flash" performance in a short time. Vlog is something that the audience and bloggers experience together, which has a certain sense of participation and existence, while short video is just a simple bystander watching a performance.
