Premiere Pro H.264 Export Problem: Disorder video and audio

[shihchiehc73951788]

Hey Guys,
I have reInstalled lots of versions of Premiere and the problem still goes on>

When I export H.264, I found it always have some part of the video and audio, show up in the wrong time or disappear. Wierdly, the corrupt part will be different each time I exported.
The footage I use is only one sequence. I have work for the same projects for many years, and didn't occur this kind of problem before. I am wondering if it cause by my Hardware or Premiere bug?

You did not mention Premiere version and build and your comp setup but if you are using a Nvidia card make sure it is set to the most current Studio Driver.

As Ann mentioned, the team does need more info to help you find a solution, @shihchiehc73951788. See: How do I write a bug report?

I hope the team can help. Sorry for the problem.
