Why Is My Computer Running Slow

sorry: if at some parts the words don’t move with my mouth. I tried my best editing it, on my slow computer The sound if its not that good. and the video quality Process of how the song was made I played the instrumentals on a piano, recorded it with my mp3 player, transferred it onto my computer. Using audacity, i recorded my voice and added different sound effects, such as snap my own fingers and hitting tables. I’m sorry if its not the greatest. OneLove I would like thank my friend Laura Martinez that helped me shoot the school scenes. She is just too amazing. I have another video with the lyrics, you can check them out on my channel

THIS TOOK ALOT OF EDITING THANKS TO MY VERY SLOW COMPUTER and i had to produce it to wmv after i would edit like 2 seconds to make sure the syc is right, but it was blurry so i couldnt really tell, so if the sync is off im sorry
