I am currently contemplating starting a youtube channel and have a macbook air. I will most likely be editing a video a few times per week. I currently have a MacBook Air 2013 with 4GB of ram 13.3" Base. Is it possible to encode and export on an 8GB ram macbook air OR should I look at selling my current macbook air and upgrading to the MacBook Pro W/ Retina Display? I will be using an external thunderbolt hard drive as storage, so I do not need a TON of hard drive space. Does anyone here make youtube videos? I have bought Final Cut Pro X, what else do you use? Any other recommendations. I do not want a desktop because I will be going to school in England at the beginning of next summer so I need something fairly portable. Do you think 16GB of ram is necessary/required? because I don't know if I'm willing to pay $300.00 for apple ram. Thanks! D.
