Thank you it actually helps alot! but the bad thing is that its freezing sometimes, its going pretty smooth, but sometimes my game is freezing in 1-2 seconds then going again while recording. Anything i should change in the setting? You able to add me on skype to help me out? Or you can just write it here. Thank you for helping my friend.
If you have not already, install optifine. It is a mod which will give you more settings and help minecraft run a lot more smoothly. Make sure vsync is off and also (assuming you have a 64bit system) install and/or update 64bit java. http://java.com/en/download/manual.jsp
Also don't use 12Gb ram, you have 16gb so 8gb will work as well and leave more room for your other programs (such as recording software). You can look on youtube/google for codecs and settings in dxtory to improve recording even more and I would advise you have java and minecraft installed on your ssd and the recording saved to your hdd.
