Ran into a ‘fun’ issue and I wanted to let others know in case I’ve advised them in the past. I’ve learned that RV’s
name tag on movieprocs require the url_safe version of base64’s encode, otherwise
/ characters will break the movieproc and you’ll get default args to your movieproc.
+ characters as valid characters in addition to a-z and A-Z, the url_safe version will avoid those characters.
