Converting MySQL default format from Antelope to Barricuda

I have some software that I need to upgrade.
It requires Barricuda format, but my MySQL by default uses Antelope.

I found a you tube video that show how to do this:


Basically, from PHPMyAdmin, I enter 3 commands:
SET GLOBAL innodb_file_format = barracuda
SET GLOBAL innodb_file_per_table = 1
SET GLOBAL innodb_large_prefix = 'on'

Does anyone have any experience with this, or could confirm it looks right?

Thanks

Joseph
