This is usually caused by either mismatching your project settings with your source video or by using incorrect output settings.
What type of camcorder did this video come from and how did you get it into your computer?
Which settings did you select when you started your Premiere Elements project?
When I started the project I just took whatever the default settings were, which as I'm checking now is NTSC-DV-Standard 48kHz. I'm looking more into it since you suggested this, so I'll let you know if I find anything else.
As for how I got the video. It's from my Canon Vixia HG20. I imported them to my computer first, and then used Premiere to take the files that were already in my computer. As I stated in this thread: http://forums.adobe.com/message/3360868#3360868 , I couldn't import directly from the camcorder to Premiere.
Changing the settings for the Project seems to have done the trick! Thanks!
The only thing I could see different is that the sound seems to be a little quieter in the exported video compared to the original. Weird I guess, but nothing that I couldn't fix in editing.
By the way, do you know how I could set my new Project settings as the default when starting another project?
Glad you figured out the project settings, Mehzers!
As I explain in my books, once you've selected a project setting, it will remain your default until you select another. So, if you've selected the correct AVCHD project setting, you've made it your default automatically! Happy moviemaking.
