When producing a company promotional video, the following things are very important and should be considered.
First of all, the content is the most important thing since it plays an important role in whether the video is effective. We should include some interesting and informative information in the video in order to attract our customers’ attention. If the video is boring, customers may not even bother to watch it.
Commentary, on the other hand, should also be taken into account because it’s impossible for the video to include every detail, the commentary may serve as an explanation to the pictures and a supplementary device for what can’t be seen in the video.
So that’s why I think these two factors are both important.
