I want to make a video and i have a couple of replay too but i dnt know what to do after could someone help

P.S make sure it works for Mac computers

you have to download a screen capture program
there are many out there but most cost money
fraps WILL NOT work on macs
after you use youre screen capture program to get a video file edit and compile the clips with a non linear video editing program ie sony vegas, windows movie maker kk?

Thank you but if anyone knows any free site post here please
