The most important thing is whether the content is compelling or not. If the content is good and your channel attracts many loyal followers, then whether the content is short or long is no longer important. Focus well on the content and find a loyal audience, and you will succeed.
Shorter than 30 seconds risks losing the concept, and longer than 2,3 minutes usually drops viewer retention. The key is to deliver your idea clearly, as quickly as possible, without cutting the essence.
