SUPER job John.
I am certainly "of the opinion" that you need to find the music (first) that inspires you to make the movie),then fit the visuals in, as indeed you seem to have done so well here.
I have made a lot of videos and most "royalty FREE music" ----isnt. It costs.
Consequently, ive used most of the free favourites from "BENSOUNDS" others are left but they cost but strangely the costing ones are no better than free ones.
Where is this music from plz? Is it via youtube, as I haven't got around to trying their music as it appears you add the music after the visuals are uploaded, and as such I cant do that because I need to have control of titles, film, and music to blend it inside iMovie.
Very relaxing autumnal video to go with a nice cup of coffee perhaps?
