Thanks for the reply and encouragement! The reason I have little to no info on the YT page right now is that their record label is going to officially host it on their channel when the album drops in a month or so, at which time I’ll be taking this one down. I needed to upload it so that the band and the label could show it around conveniently! Otherwise, you’d be 1000% correct in taking care of the copyright info.
I’d like to make more videos like this, the pay is pretty solid and Synfig just works so well for my needs. I’m primarily an illustrator, and the cutout processes available from Synfig are perfect for my workflow.
