Would you please offer some more detail about your project, the source of both the audio and video and your output choices?
The video is GoPro footage and the sound is from iTunes.
I don't have a GoPro and have not used iTunes for a long time. Consider these as suggestions.
GoPro footage is frequently mentioned as being difficult. I think it has to do with what is called variable frame rates. The normal solution is to use GoPro's own software to "pre-process" the footage into a more common 1920x1080p30 or 60 MP4 file.
iTunes tracks are known for compression, formats and copy protection to make it hard to use. Copyrights are involved. There are utility programs that can convert iTune formats to useful MP3 files. I once converted everything I bought for an iTouch through iTunes. I don't remember the utility I used.
Hope this helps. With luck a GoPro expert and a iTunes expert will pitch in.
The utility that can convert iTunes .m4p audio or .mp3 audio to WAV files is a free download called Audacity.
That said, are you saying that the audio is only scratch AFTER you output your video from Premiere Elements -- not when you play the timeline?
Yes that's right, the sound is only scratchy after it's been saved with any other file extension besides .prel.
Steve Grisetti: I noticed that my default video format was "Full HD 1080i 30" and I came across your video to change it to "AVCHD 1080p60" if I was having problems with video playback. I made the changes to a new file, imported a few frames from my GoPro and audio from iTunes and saved it as an MP4 file. That worked. Thanks for your tutorial video Steve!!
The only issue I'm running into now is that I can't change my original video's format so I may just have to suck it up and make my original video all over again.
It sounds like you're on track to resolve this issue, karla. (And thanks for your kind words about my tutorials on YouTube at on my web site, Muvipix.com!)
Have you converted your music files to WAV files, as I suggested above?
