Let me check out your short content and get back to you later.
Or actually, having read your full (long) post, I don't feel I even need to do that before writing this.
I totally feel you. I myself am someone who tends to use a lot of words (besides my quiet time), but Steemit has definitely made me think of compressing my output. Mainly due to lack of views on my posts. At the same time, I am as a visual person too and I am looking for ways to incorporate that in my work on here.
The question is, how much do you adapt to a platform/ conform to the audience, without losing your voice// style? A question I asked myself as a filmmaker too.
You yourself seem to have talent (for lack of a better word) for both articulate long posts and shorter (more visual) content. That said, I wouldn't feel too bad for 'rewarding' yourself for the latter. Especially after investing so much time and money in Steem(it).
I totally understand that it might sometimes feel wrong/ askew though. Don't feel bad about that either.
Keep doing what you do - as long as it feels good enough/ in line with you - and please keep sharing these ('boring') longer posts every now and then to talk about important questions/ issues that many of us wrestle with but few actually share, let alone in such an articulate way.
Have a great day!
