Someone who has a quadcopter created a serene 4K video of Lac de Salanfe in Valais, Switzerland. The video is now linked from the Wikidata entry page for the reservoir (https://www.wikidata.org/wiki/Q680375) and Wikipedia pages in English https://en.wikipedia.org/wiki/Lac_de_Salanfe, French https://fr.wikipedia.org/wiki/Lac_de_Salanfe, and Russian https://ru.wikipedia.org/wiki/%D0%9B%D0%B0%D0%BA-%D0%B4%D0%B5-%D0%A1%D0%B0%D0%BB%D0%B0%D0%BD%D1%84 .

If you watch the video, I recommend watching it in full screen mode.

What's making you happy this week?

Good afternoon,

I filmed a short, 8:25, 4K video [1] of the lake Lac de Salanfe [2] last weekend for its Wikidata page [3].

For the first time I used a 3D flying while filming an aerial footage. It starts at 6:33. The difference with usual aerial filming is that a quad moves not just on a flat plane in the air with a constant altitude, but in three dimensions.

The idea is to fly following a relief of an geographical area and by this creating its three-dimensional representation for including it as a part of a video.

This lake is located at an elevation of 1925 m, so the air is a bit rarefied. The quad which I used weighs less than 500 grams. It has got a modular design. I plan to upgrade some of its components, especially switching to the digital ESCs, so that the aerial footage would be smoother. This time it was just an experiment.

It is possible to view the same video on Youtube [4] too.
