Use case or problem
If a video has large resolution, embedding it into md doc, it may be very large in the preview. So a way to control the video frame size is needed.
Proposed solution
For now we can use syntax  to control image size like this: , so I suppose this could be also implemented to a video like these:


![[demo video.mp4|180x320]]
Current workaround (optional)
HTML label. Not handy to use.
