Tried to download WMM, but had to add it to an account cart, then it wouldn't let me log in, apparently I had an account yeas ago but had long forgotten the password. I expect to have to add a credit card to my account even if this app. is 'free.' Typical complications to irritate potential users.

BTW to upload an audio track to YouYube they force you to turn it into a movie first. Never did work out how to do that.

For video work the one and only app. I ever thought was worth purchasing was VideoRedo and VideoSuite.

BTW YouTube vets uploads for copyright infringement and uses AI to detect and id even clips of copyrighted works. It is also draconian over checking for material unsuitable for kids, although it tolerates depictions of such as nakedness and gay sex FGS.
