There can be no free short video training. And most of the short video training is unreliable, because they just want to make money, and there is no real way to make money for you. If they really earn so much money, then they will definitely not teach others.
With the rise of short videos, any enterprise, any studio and individual need to edit and produce a large number of videos to display their brands, vibrato, friends circle, Taobao and other media channels. Moreover, the techniques of short video shooting, editing and special effects production do not require any artistic and musical attainments, and are basically fixed routines. What style and rhythm do you want can be easily mastered after three or four months of study.
