(adsbygoogle = window.adsbygoogle || []).push({}); ive made a video which needs commentray. I just need to know how i should do it and what is the best software or whatever to use.

You can do voice commentary lots of ways. Some people like the big commentators you find on machinima and shit obviously can afford to expend on a proper microphone to make it crystal clear, but if you haven't got money for that you can use a digital camera or an Xbox mic or an MP3 player! Just take the sound and put it over the video.
