Will this solve my problem? (Nvidia Shadowplay)

I was wondering which section to put this thread in, but in the end I chose this one.

So, I have been using nvidia's shadowplay a lot recently and there are features that need to be added in but one that I am wondering about solving the issue on the variable frame rate.

Before the 1.8.2 update video's would be recorded at 1080p at 60fps. When recording my frame rate would be around 40-90fps. I think this is what causes the variable fps?

Now 1.8.2 has been released with the ability to change the recording frame rate would setting the recording fps to 30 stop the recording framerate fluxuate or do I have to handbrake my files before putting them into prem pro?
