From the perspective of getting ranked on video tags longer titles can sometimes be better. It does make a difference in getting ranked on more tags if you can fit more keywords in, and sometimes this makes me want to make the titles longer. I've changed some video titles and got ranked on tags that I wasn't previously ranked on just by putting different words into the title or more keywords. So I would choose your title carefully based on which tags you are trying to specifically target. At the same time you obviously don't want to turn people off with odd titles so you have to word it so the keywords seem natural.
For example the titles you have, I would choose the bottom one if you were trying to rank on the tag "software tutorial". (that's probably not a doable one because I imagine it would have a lot of competition but just as an example) It would be much harder to rank on that tag with the other title. If you're trying to rank on any tag with the word "tutorial" in it, you probably want "tutorial" in the title.
Longer titles can be confusing but I think if you word them right they are very useful for getting your video ranked well.
