Does anybody know the exact way to record avi for N64 roms?

I am doing long plays of games you can see my game plays in emuparadise lets plays...So I needed a N64 emulator with avi recording feature and some people suggested me to use Mupen 64 but I tried all the way it just records audio but no video I used mupen64 and mupun64 plusplus also but I get some kind of errors and every time it fails..If anybody knows how to fix this problem please let me know and others as well as they may also come to know...

I need step by step procedure so kindly post it in detail so I can use it...
