Most videos you see on the news is to some extent faked. That is just the nature of the news. There is a narrative, and that narrative determines what is broadcast. You are being played.
This particular video was immediately removed after it was posted by the "White Helmets." But a copy had already been made:
1: The White Helmets receive funding from UK ($65m via UK Foreign Office), US (US State Dept via USAID $ 23m), Holland ($ 4.5m), Germany ($ 7.87m) and Japan (undisclosed sum from the Intl Cooperation Agency), Denmark (undisclosed sum) – via the Mayday Rescue “foundation” that was set up by the British ex-military trainer of the White Helmets in order to transfer funding to the White Helmets. The White Helmets also receive equipment and supplies from various EU member states. This funding is concealed behind the generic heading of “Emergency Health and Relief Support to the Population Affected by the Crisis in Syria”, through the Directorate-General for European Civil Protection and Humanitarian Aid Operations (DG-ECHO), formerly known as the European Community Humanitarian Aid Office.

But remember, you are being played.
