The files in this directory are not meant to be tracked in git.ipng.ch.
Instead, they should be added to media.ipng.ch/sabbatical/media/
and then pushed to the nginx0.*.ipng.ch cluster.

After pushing, you can use tags like this, both in the staging and in
the production environment:
{{< video src="https://sabbatical.ipng.nl/media/vdo/IMG_0406.MOV" type="video/mp4" preload="auto" >}}

Note: the production environment does not allow resources to be loaded
outside of the domain itself for security reasons, but `hugo serve` is
not as strict.
