I prefer video in media information.
The reason is because, when the information is in a video form, you can understand it more. It is better than text because you still need to visualize it. It is better than audio because you still need to understand what is the speaker talking about, especially if the audio is not that clear. Lastly, it is better than visual because you still need to interpret the picture. If the media information is in a video form, it is like the combination of all those 3 ; text, audio, and visual.
