How can I sync two videos together in Corel VideoStudio Pro X3 I have two videos of a dance at a dance competition taken by two different people. The videos are of the same dance but are from different angles.

I want to create a single video that contains both videos side by side and synchronised to the same point. The videos start and finish a few seconds apart from each other and thus are slightly different length.

My video application is Corel VideoStudio Pro X3. How can I do this? I imagine that somehow using the audio this could be done. The music should act as a good guide for syncing them together.
There is no way to do this automatically. It has to be done manually by matching the frames together from the two videos. This can be done by placing the videos in separate overlay tracks and works for two or more videos.
