What did I learn from The preliminary task?

When Filming the preliminary task, I realised that it wasn't as easy as it looked to sing along to a song in time and make sure that you are able to see your lip sync, but to help this you can sing out loud and film whole takes of the song so you can choose bits when editing. However the main problem was whilst editing, as we thought we would try to make a split screen, which ended up as lots of clips (although all in time) popping up everywhere and covering other bits as it was all slightly confusing as we had so many different layers.
