It still has a slightly too much red in the shot it see the ND filter is causing it, cause looking at the footage behind my laptop I could finally see that there are some shots that are very red or even looks like a pink cast over the whole image. Its actually something that is cause by the ND filters cause they are not doing a good job in filtering the red color spectrum. It seems if you really want to use an ND filter you really need to pay allot of money
