<b>Warning!</b> Blazy Filter is useless and broken when you enable <b>Media embed</b> or <b>Display embedded entities</b>. You can disable Blazy Filter in favor of Blazy formatter embedded inside <b>Media embed</b> or <b>Display embedded entities</b> instead. However it might be useful for User Generated Contents (UGC) where Entity/Media Embed are likely more for privileged users, authors, editors, admins, alike. Or when Entity/Media Embed is disabled. Or when editors prefer pasting embed codes from video providers rather than creating media entities.
