Reviewing our film

We have reviewed the editing we have done so far on our music video and we are nearly coming to an end. Nevertheless we have identified that the first 30 seconds of the film does not flow with the rest of the video so we have to go back and film some more and adjust the lighting. The first time round we got the lighting wrong and the position of the singer wrong. We couldn't actually see the character singing because it was too dark and the quality of the camera was poor as well.
