Can I get a suggestion

Hey guys the reason I am posting this is to ask you guys if you have any good suggestions for a  free gaming  unregistered screen recorder download for pc so I can record some stuff and I have tried bandicam,Camstudio,hypercam,and camtasia but most of them caused lag to my minecraft and hypercam wont let me change the color scheme that I need,so please if you guys have any suggestions feel free to post about one.Thanks!!!!!!! 

Screen-Cast-O-Matic

All screen recorders will lag your mc, Its just what they do.
For free ones I would recommend bandicam.

Not all of them I've used ones that don't lag but they don't even work.

Try Open Broadcaster. It's free and pretty good.
Look up a youtube vid to set it all up correctly.

Ok cool I'll go check it out.

Problemo solved I got bandicam again it turns out I just wasn't using the right setting to record minecraft very well,but thanks for your suggestions!!!!!!!!!!
