An informative video of the route

[Isca-camigo]

It is in Gallego but even if you don't understand the language you can get the general gist.

I would also say that many of the shots are on and near roads, it could be that they drove to certain points and filmed near where it was accessible for them.

The end of the 1st etapa they use is Terras de Bouro which is 28km from Braga, but if you make the Albergue in Caldelas as your 1st stop( 17km from Braga) then the next day you bypass Terras de Bouro and take an alternative route with less descent and ascent and follows the Roman road, it's adds about to 2km to the whole Camino, the end of the stage is Campos de Geres where there is 2 youth hostels, it is about 30km from Caldelas.

It is in Spanish or I understand Gallego

Ha! It is in gallego, but it must be a native castellano speaker. In my experience, when I listen to newscasters or other native castellano-speaking people supposedly speaking gallego, I can pretty easily understand them. But when I am on a camino in a small town and a couple of the old residents get going, I can’t understand a word, not one word.

I was walking with my grandson a couple of years ago and we got off the route on one of those shortcuts that actually turnout to be long cuts.
We went in to a local bar in a little farm community for a cold drink and I was confused as I had to pretty much order from the bartender by sign language.
We sat and were trying to understand what the local farmers were speaking. My grandson had pretty good school Spanish and neither one of us could pick up one word.
It did suddenly dawn on me where we were and that they were speaking real Gallego. The bartender did not (or refused to) speak castellano (or English, of course).

I wasn't sure myself, I had to ask my partner who said it was Gallego, her childhood language was Gallego.
The murder mystery series on Netflix 'Bitter Daisies' apparently gives 'pure' Gallego so that's a good way in. + The first series was in and around A Estrada on the Camino Geira, the 2nd series seems to be having a love in with the region the Camino Invierno is in.

Yes. Amazingly easy to get the gist of that Galician. And here is the same video narrated in Brazilian Portuguese:

That must be it. I also understand Valenciano which is even more like Spanish. Forget Catalan
