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.
