First test footage of DJI's Zenmuse X7 camera in 5k using a 50mm lens. The location is Vinci, in Tuscany, the birthplace of Leonardo da Vinci. The time was around 4pm and it just stopped raining. Temperature was around 4 degrees Celsius. Footage has been slightly color corrected with Red Giant's filters.

Oh, for a sample you'll have to ask the owner of questioned original footage, since I do not have X7 camera. I don't contradict your statement. I just simply doubt YouTube player ability to faithfully reproduce published video material, that's all.
