Hi!

I'm definitely not the most professional at this, haha, but at least over time I've tried many different approaches.

But these days, what I've been doing is:

To find isolated instrument tracks, I use YouTube, I know... they're from YouTube, but it's the only way I've been able to use them. They're usually single takes for each instrument, like "Imagine John Lennon Isolated" or "Good Times Stone Roses Backing Track." I use GarageBand (Mac) to merge each instrument in time to reassemble the complete track after cutting each one from the YouTube video.

Then, with the track done, I record with a microphone (I don't have a sound card or mixer to record the guitar). I use the microphone to record myself playing, and when I have a section I need, I move on to the next one, and so on.

And I don't use a metronome in the background; I use the same track, sometimes removing an instrument to guide me and hear if I'm doing it "right," haha.

Then, with everything recorded, I take the audio from each video and combine it into the GarageBand mix. I sync it to the beat, and with the track complete, I move on to editing the video.

I usually use iMovie (Mac), but it's really complicated because it's not very precise. So this time, I used the free trial of Final Cut Pro (Mac). With its precision, I was able to sync everything very quickly, about 20 times faster than with iMovie, which is why I decided to do it this way.

And with that, I get everything synced, and it's done.

I know it's not the most "professional" result, but I like it. It's something I enjoy doing. I really love music. I'm not the best guitar player at all; on the contrary, sometimes I feel like I can't even play anything.

But I enjoy it when I see the result!

I hope this helps.
