I play 2 different instruments, and would like to make a video of me playing both instruments to the same song. Now, I can’t really clone myself, but I can record me playing the first instrument on video, and then during the playback, play the second instrument along with the video while recording.

I would like to do this in a way where I don’t have to merge or synchronize video, but rather - after the second video recording everything is merged, synchronized, and ready to go.

I own a Logitech webcam. One way I’ve thought of trying to do this would be to record the first part, and then during playback, set up a screen capture program that is set to capture both:

The first video playing back, e. g. in VLC media player AND The Logitech software window that displays what is currently being recorded (the second part).

Has anyone tried this type of thing, and can share whether the above method will work, or can suggest a better way to do it ?

Thanks in advance,

Joe
