You mean how do you make a vid from aeroflypro or other sims?
You need a program that will capture the video for you. Fraps is what shortbus reccomended to me. It is a downloadable program cost is $37.00 usd. works very well. then you can use microsoft movie maker to edit your video and add sound. I am still learning my way around this stuff, it is a heck of a lot of fun to do. I think it could be addicting. I am sure there are many people on here that are more qualified than me to help you make a vid, but I will help in any way I can.
