So now I have 4 videos, each of a person singing along to a piano music file being played. As each video is being recorded by an Iphone, both the piano music being played through speakers, and the singing are being recorded.
So I wind up with four mp4 video files, each containing audio that is a combination of voice and the piano accompaniement..
I then import the four videos, place each in a trrack, highlight the four audo tracks, and click the synch by audio button.
When I tried this with only two tracks it seemed to work, but it seems not to work with four tracks. I might get three of them synched if i am lucky, but not all four. I realize it is asking quite a bit for the software to synch multiple audio tracks when the audio tracks are composed of a combination of the piano music mixed with different voices.
I am new at this What approach should I be taking here? And suggestions much appreciated.
Thanks
