Hollyland Mars 400S Pro - Do You need a Video Transmitter?

Video transmitter from a solo filmmaker perspective with Hollyland Mars 400S Pro as an example.
There are a lot of technical reviews and tests of Hollyland Mars 400S Pro on Youtube so in this video I focus more on a practical use case scenerios, so you can see if you should get one for yourself.
Hollyland sent me this transmitter for free but it's not a sponsored video so you will hear only my honest opinion.

Subtitles in English and Polish are available.
