Video essays cost money to make. There’s the cost of the research, the writing, the assembling of materials, the editing. It adds up to hours and hours of work for something that takes minutes to consume. My average just for editing (not anything else) is about 8 hours of editing for every 1 minute of video essay. So the 9-minute Jackie Chan video was around 72 hours of editing. It was probably at least double for research and writing.
