Hi ebbinjose. Some of the post formats, including the Video format, are not activated in the theme version in the WP theme repository. See this post for more information. If you want to upgrade to the version available on the theme website, here is some information.
There are actually two versions of the theme: one in the wp.org repository (v1.3.9 with an upgrade to v1.4.5) and one available on the theme author’s website (v2.2.0). There isn’t a direct upgrade path from v1.4.5 to v2.2.0 because they are aren’t quite the same. The version on the theme website contains addtional functionality which is described there.
To upgrade from v1.4.5 to v2.2.0:
1. Activate a default WP theme like Twenty Fifteen.
2. Delete the currently installed version of Hueman (if you’re using a child theme, delete the parent theme, not the child theme).
3. Download the new version zip file from the theme website.
4. Install the new theme in your Admin panel by selecting Add New > Upload Theme > Choose File, then select the zip file.
5. If you’re using a child theme, reactivate the child theme.
If you want to use a child theme there is a pre-configured theme available. Go to Theme Options and select the Help tab in the upper righthand corner. The link for the child theme download is listed there. Install as noted in #4 above.
Couple of notes about the version on the theme website:
1. You will not receive any automatic notification of updates. You’ll need to check the website periodically for new versions and you’ll need to follow the same process described above to install an updated version.
2. If you use the built-in Custom CSS option you’ll need to save that code or the custom.css file before you upgrade.
Also good information in the detailed theme documentation. A link to the documentation is located in Theme Options under the Help tab.
