Hi there, 

I'm trying to export a 6 minute video in Premiere, in the edit the audio is perfectly synced but after export the audio is a whole minute longer than the video and completely unsynced. It isn't happening in other formats but I need it in H.264

How can I fix this?

If the footage is variable framerate convert to constant framerate with Handbrake before bringing into Premiere.

as Ann suggested, you've probably got sources that have a variable frame rateuse mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate

and here's a tutorial on how to use handbrake
