Why does downhill look very flat when viewing headcams!
Because if you are riding on the flat or downhill or uphill the bike is always at the same level/angle as the camera pointing in exactly the same place, down the trail.
Until recently, most lenses are crap, left over from security cameras and use convex lenses (fisheye), meaning trees on the outside of shots would bend making it even more difficult to work whether the rider is going uphill or downhill.
When a lense capable of recording to a blu-ray standard becomes available things will change. The current 1080p and some of the older 720p are half decent though.
Then youtube compresses the hell out of the videos, meaining pixels of information are merged into blobs of similar colours, making it harder to see detail in trail features. hi-def on youtube is a joke. The Beeb do broadcast occasssionally in true hi-def and itv get somewhere near but s*y is way off.
And finally most video compression relies on parts of the image staying the same from frame to frame, think someone walking left to right across a screen. Only the area where the person moves changes and the background remains the same. However, when you are bombing down a trail every frame is different.
At the end of the day your asking a tiny mechanical device to record onto a tiny memory card the experience of riding down a hill at 30mph.
