Bridge construction propaganda film, animation+others, about 10 minutes. Approximate price
Animation is very expensive. We have made a video of the bridge ballastless track before, and the production cost is 200 RMB per second, which is made in Wuhan. You can refer to this price. It might be cheaper to make a video. We'll find someone from the TV station, shoot for a few days, and finally dub. In short, a set still costs tens of thousands of dollars.
