I don't think the goal here is to get as many views as possible, but get the best information out there.
From my point of view, tutorials have to last the time they last. It is, after all, a tutorial. Wouldn't be worth much if it skipped important parts due to length because some people prefer short bust of info instead of larger ones.
The only other possible approach would be to split a long video into smaller ones, but then, why not watch for a while and note the point where you stop? Or simply tag it as "Watch later" until you've gone through it. :P
Hey Jack, i've just finished watching it now and actually the length was fine and definately appropriate for what was shown. But, for example, the 'particle emitter' which was 10 minutes could have been put into a seperate tutorial, so users who search 'jmonkey particle emitter' or something, would have it there :). I don't mean cutting out important parts at all though! No way that tutorial would have been possible condensed into 15 minutes, there was so much information which is brilliant!
I'm not sure, it's just a suggestion :D.
I watch quite a lot of online tutorials and have personally found the 10-15 minute ones better for taking in information(but these are generally far more boring haha), however, I have problems with concentration and this is probably the longest tutorial by far i've ever been able to watch without feeling 'cmoooon hurry up and get to the point' and end up skipping lots of parts. I think this is because Normen manages to condense it in a way that every second does provide really useful information.
Thankyou very much Normen :). You've really made things sooo much easier with your last two tutorials!! Are you planning on doing more?
