How to Sync Audio to Video in an AVI File
Having the audio properly synced to a video track is very important. Most video editing software offers audio syncing tools. Sony Vegas, Adobe Premiere Pro, Avid and Apple's Final Cut Pro allow easy audio syncing. The syncing is done by isolating the audio from the video track and repositioning the audio correctly on the time line. Perfect audio syncing takes practice, but it is not difficult to master.
