I believe this question is on-topic.
- Because it's specifically targeted at this audience. He wants to show us his solution to a question here on gaming, which I'm sure a lot of you would want to do too
- Because he's using a game-specific tool. FRAPS = short for frames per second, a tool to show off how many fps your awesome GPU can generate
But isn't encoding like totally off-topic?
Well encoding might not be directly about games, but come-on so are questions about gaming-slang, who the best pro-gamers are or any other meta-ish gaming question. We allow those grey-area question, because we dig them and think they help out the community.
But a similar question has already been asked and answered on Super User!
Duplication across the network is fine, as long as the question suits it's destination. As a moderator on Super User, I can't begin to explain how many different wordings users can have for asking encoding questions. Because let's face it: encoding is really a geek speak term!
All this question really is about is shrinking this darn screencast, so he can put it on Youtube. The fact that we geeks or super users call this encoding, doesn't really help the guy, because he has no idea what your talking about. Telling him this, doesn't help him either, it will just make him dislike the site.
So should we start allowing any grey-area question now?
Hell no! But this question is about helping a fellow gamer in need, who wants to help out another gamer in need. Isn't that what this site is about? If we start bashing these questions, then we do our community as a whole a disservice.
My advice: chill! And start looking for bad questions to close, instead of trying to hinder enthusiastic community members, from helping others.
