Subject: [OSM-talk] adding Wikimedia videos to OpenStreetMap objects
To: Talk Openstreetmap <talk(a)openstreetmap.org>
Dear fellow mappers,
It is possible now to upload to the Wikimedia Commons the videos which
illustrate Wikipedia articles. On Saturday I went to the highest summit of
the Swiss portion of the Jura mountains, Mont Tendre
<https://en.wikipedia.org/wiki/Mont_Tendre> , and filmed a short, 4
minutes, video about it.
Then I added this video to the respective Wikimedia category and to the
Wikidata page, and added wikidata=* and wikimedia commons=* tags to the OSM
node of the summit:
http://www.openstreetmap.org/node/343335042
I used for filming the cameras Sony RX100 V and DJI Osmo, and for the
aerial footage the latest DJI Phantom 4 Pro+ quad-copter. The Wikimedia
accepts videos in the free open WEBM format, so I converted the MP4 file
into WEBM with the ffmpeg <https://ffmpeg.org/> command line tool.
The quality of the resulting WEBM video:
https://commons.wikimedia.org/wiki/File:Mont_Tendre_Jura.webm (select at
least 1080P resolution in the player for viewing)
is comparable with its Youtube version:
https://youtu.be/pgNiCYzr7sg
The DJI Phantom 4 Pro+ has got a camera with one inch image sensor and
improved lenses. In my opinion, it is the first aircraft of this class
capable to film really useful aerial photos and 4K aerial videos. Creating
a good video is not a trivial task, still there is a lot of information on
it, and the quality equipment is readily available.
And it is kind of interesting. In fact, we could climb on the Mont Tendre
only from the third attempt. Two first attempts failed due to the snow,
wind, low outside temperature, and the remoteness of a location (it is also
the most isolated mountain of the canton of Vaud), besides we had to carry
the equipment. Probably, I would never did it in winter, if it were not for
filming.
A video may convey much of significant information about a location. It may
provide not only ground and aerial footage, but also some practical advice
and insights via a microphone. Perhaps, in future we may think about
creating a video=* key for direct linking to the videos with a Creative
Commons license. But even now it is possible to do it via wikidata=* and
wikimedia_commons=*.
With best regards,
Oleksiy
