Hi, I am a beginner in this thing and i am a music lover. So i want to start making videos for my you tube channel. My question might sound stupid but hope you won't mind giving me the right advice. So my question is - how do i record guitar and vocal using audio interface while i shoot the video at the same time. I can record my audio(guitar and vocal) using audio interface(focusrite solo) connected to ipad/iphone but how do i record the video also at the same time using its camera? Can i do that or do i have to use an external video recorder and then sync audio and video later on?? For example Focusrite has this product called itrack pocket, an interface with guitar input, in-built microphone and a cable that connects it to iphone/ipad, which helps in recording your audio and video at the same time. But the problem with this is i cannot connect external microphone(for better vocal recording). So, i want to upgrade a little. Please advice me how do i do that.
