Why are food websites introduced in graphic form instead of video? Isn't video more direct?

The requirements for graphic shooting are low, the occupied space is small, and the requirements for server traffic are low. Post-processing can produce good drooling effect. Learning to cook is also directly using pictures and texts. Reading pictures and texts saves time, and you don't have to watch videos from beginning to end. Also, have you ever tried to cook according to the recipe, just open the page and cut the video with your mobile phone in one hand? Do you still have time to look at the front and back? That's really hehe. The video only introduces the application of tongue class.
