The problem is that when I export the video, there is static in the beginning of each clip, which goes away after a little while. It's very prominent when there are a lot of quick cuts. In the longer clips there is static in the first 5 seconds or so and then it sounds fine. The worst part is that I can only sometimes hear this in Premiere Pro, mostly the audio sounds perfectly fine start to finish, but it's there every time I export the video. I've been using the youtube exporting preset. I've also tried .avi file and it's there, too.
The mic we used in the shoot was a Sennheiser MKE400, and the sound was quiet and there was a lot of static, so I had to use compression and denoiser effects.
Please help! Here is a short sample of the video:
