I find on Ask Ubuntu that I answer questions better than I ask them. No big issue, it is something that I am working on. So when I create a question I put a lot of thought into it, witness this Q&A effort here:
For this question I found a gap in Xenial Xerus: FFmpeg can produce hevc files but WinFF cannot as it does not have a suitable preset. With a little research I produced a good preset, tested the installation and running of the preset and finally created the Q&A.
A couple of Close votes came in and this is fine, I am more than happy to listen and be guided by Community needs and I have altered my question to make it both clearer and less broad as suggested. A comment left after the question outlines this for the benefit of others looking through the Close review queue.
But what I am after with this question is this:
Consider leaving some constructive comments intended to guide a question along a better path along with your Close vote. This will be particularly effective with those question writers who have perhaps been with Ask Ubuntu for a while and who are probably keen to produce a good quality question which will enhance the site...
Such feedback in Comment form would certainly have guided me along in fine tuning my own question and I suspect that this is probably true of many other questions asked on Ask Ubuntu.
That is all :).
