When I move over a wav file into the software, the video speeds up. the audio is fine. i play the file outside the software everything is in sync, it only happens when i put the file in movie studio
When you import the WAV file or the video files are you getting a message that it does not match the project settings and do you want to adjust?
What are the project settings? A screen shot would help.
Download and install MediaInfo and analyse one of the video clips and WAV files and post the results, see this tutorial on how to setup MediaInfo and analyse a video/audio clip for all the data required.
In case it is needed, I would suggest you put your computer specification, Windows version and program version, see this topic for what is required and please quote processor and graphics card make/model in full, in your Profile Signature
