I've never used video editing software - the most I've ever done is upload standard videos to youtube!
What I'd like to do is create 2 videos but then play them side by side in a split-screen format, where you can see and hear both simultaneously. So when uploaded to youtube for example, it appears as one split-screen video where clicking play will play both.
eg a man playing a guitar on one side, and the same man singing the melody on the other side, so that when you click 'play' it all works together.
Can anyone help me with where to start, what software I may need etc?
Thanks in advance
