If you are talking in a purely Eyes on FF sense as your audience, then yes, videos are not people's preferred method of LP around these parts. They much prefer screenshots and text.

If you prefer making videos to that then I say just make videos and don't worry about the reception you get on EoFF. YouTube itself has a potentially vast audience you can appeal to and gain a following, although it's a heavily over saturated market which is difficult to break into. You need to have good SEO on your description and video tags, appealing thumbnails and appealing video titles.
