Issues With Guitar Synching

During the filming for the performance, we ran into some issues with the guitar synching. Our main actor who was also lip synching in the video and being our artist couldn't play the guitar, and it looked very unprofessional. We got around this by using another friend who could play the song. We carefully recorded him playing the song, so that you couldn't see it wasn't our original artist and then synched it perfectly with the song. This ended up really well, with the synching then being perfect and the whole project looking more professional.
