Thank you for your support, dear brother.
The process is really simple:

  1. Record the base with a single instrument (guitar) and voice.
  2. On that first base I record the audio and video of the other instruments (bass, second guitar and percussion).
  3. Finally using a video editing program (I use Wondershare) I synchronize the shots and add the mastered audio.

It is very fun to do it.

Hugs!
