Converting FLV (VP6f) to Mp4 (h264)

[riddlemd]

I have some flv that I need to convert from FLV (VP6f) to Mp4 (h264).

I've been using SUPER which uses (ffmpeg), the problem I am running into is audio desync -- right off the bat, it's messed up.

Try some other tool, like Avidemux.

I'm a pretty big noob when it comes to this stuff, I've only tinkered with it on and off.

But lets say my orginal FLV was 20fps and When I ran it through ffmpeg it was being set to 25fps would that throw off the audio?

Yes. The problem is that FLV can have variable framerates.
Typically what I do is run the FLV thru VirtualDub, and find the average framerate, then encode.

DirectShowSource with Convertfps=true can usually resolve VFR issues.
