That's include buddy and being honest, I totally agree. I buy skiing & snowboarding films from MSP and The Orchard and they are filmed using 8K Phantom cameras and lenses, so you can imagine how they shine in 4K combined with the natural sunlight bouncing off the snow!
I will check out that documentary although as a natural bodybuilder, I'm rather horrified how the non-natural sport industry operates!
The guys in the documentary definitely cycle. However, their muscles and veins looks very alive in the exceptionally well shot 4k documentary.
