Lip Syncing Practice of Ellie

I have now filmed Ellie lip syncing to my chosen song 'The Show' so it would give her an idea of how to lip sync but also to be more familiar with the song as she would be lip syncing the majority of the song in my music video. Now I would need to edit it and put the song over to see how easy or difficult it is to match the lip syncning to the song so when it comes to the actual editing of my music video, I would know how to do it.
