I made another sculpture video, now you'd probably ask yourself why do I make these videos shorter? One person in the community said my video lacks more detail, but here's why.. I purposely made them shorter, for a creator who is still new you want people to watch your videos to completion especially on Facebook.
A short video is more likely to be completed by more people and the algorithm will push it more.
Once you are established and have an active audience u can make ur videos as long as u want because already your audience likes ur content but if ur still new u want ur videos to be pushed more by the algorithm.
Here's my handles Facebook and Instagram. If you wanna see more of my videos u can head over there but it's not many I've just started my page is about a month old.
