I am using WMM to record live vocal covers to upload onto Youtube. The video is captured on a camcorder and the sound is recorded through an external mic using Audacity. The recorded vocal and music backing track is then imported into WMM and aligned with the video footage so it matches up and is in sync. Its all good until I save the project and watch it back, its all completely out of sync. Can anyone help with this problem?

Thanks in advance,

Adam
