You need to do a search with queries such as "FPS" video software clients, etc
I see great upload videos on youtube people looking at there pc screens while playing musical instruments. And the video is way better then I have seen that some $40.00 web camera does which cannot handle fast movement witout producing multy ghost of hand like or audio is has delay. Where the you tube videos are so live and motion perfect along with audio, One would think it was from a video camera, instead of a web cam. which it must be since there close and looking stright at pc screen while fast playing musical instruments.
I posted the web camera question here,for I did not see web cam listing anywere else.
