BSR screen Recorder Settings

So I was recording this
YouTube - Dbz legends cell with cartoon shader +2xsal

Now it was like 37.5mb i size for only 1.27 playtime.. and it looked well mediocre... quality could be alot better, also it seemed to be laggy and audio a bit off.

It was recorded with BSR screen recorder with the ffdshow video codec...

Now i don't have any idea how to properly set it up so I get high quality or at least decent videos 100% in sync..

Im using it to record aPSXe game video.


System:
