Adding Video to Recording

I have been playing rhythm guitar for about 3 years and am now being asked to do more vocals. I have a small FB private group of select friends who are musicians that i have asked to help me critique my vocals. I have been recording my playing and singing with my camera phone. I want to get an audio interface and DAW so that I can mix the recordings. But if I do that, how would I add the video so they can view my posture, strumming, etc. I'm 52 years old and some of this technology is out of my wheelhouse. 

Hi, Dwayne! What kind of computer do you use?

The process will be:

1. Begin recording (video)

2. Begin recording (audio)

3. Clap a few times (so there's a big "spike" in the audio waveform)

4. Bounce/export your audio file, including the claps

5. Import both audio and video files into video editing software

6. Line up the video's audio with your DAW-edited audio (using the clap spikes as your markers). Note: some software has an "auto-sync" function that does this with the click of a button, but it's not too difficult to line up the audio manually.

7. Mute or delete the video's audio, so only the edited audio is heard and is properly synced with your video. 

Thank you Camille! I will be using a Windows 10 laptop. 

Great! Let me know if you have issues along the way. I know there will be some helpful video tutorials on YouTube as well that show the process - particularly in whatever video editing software you use. Just include the software name in your search!
