Wondering about this? Not sure if this is the right part of the forum.
I see some of the videos on GMC move between different camera angles. Surely unless you have more than 1 camera you would need to record video again for the section that has a different angle over which you would "mime" to the original track?
Regardless though, with only one single camera angle all the way, if recording both vid and audio at the same time you would need to press record for both (for me the buttons for audio and the video aren't near to each other). Wouldn't it be less hassle to record the audio first, then record the video separately (while playing the audio to hear so you can synchronize your playing), then put the audio and video together afterwards in an editor?
This way if you don't like the way you play a note but the video is perfect, or if you play the audio perfect but you move off-shot slightly on the video without realizing (for example), then you don't have to record both video and audio again due to an error on only one? or is that a cop-out because you are not really "playing" on the video, but instead playing over your own playing? What do you do?!
