Via ferrata
Also known as: iron way, cabled route
A protected climbing route with fixed cables, ladders and bridges, where the exposure is extreme and both hands belong on the steel.

What it means
A via ferrata is a climbing route equipped with fixed steel. Cables, rungs and bridges let somebody cross terrain that would otherwise need rope skills, clipped in with a lanyard the whole way along.
The exposure is the subject. A route frequently runs across a vertical face with hundreds of metres of air underneath, and conveying that is what separates good footage from a sequence of ladders.
It is not the same as Climbing footage of a roped ascent. Movement here is continuous and the protection is already in place, so there is no belay, no pause and no obvious moment to film.
How it works in practice
Both hands are occupied almost all of the time. A helmet or a Chest mount is the practical answer, since anything handheld has to be stowed before the next section rather than used on it.
A shot looking back down the route reads the exposure. A camera angled past the body towards the ground below gives the drop a reference, where a forward view along a cable shows only steel.
A bridge or a ladder is a scheduled shot. Those features are known in advance from the route description, so a camera can be left running at the far end before anybody crosses.
What to watch out for
A wide lens destroys the exposure. The one thing worth conveying is the drop, and a fisheye field of view flattens a vertical face into something resembling a steep slope.
Dropping anything is a serious matter. A camera that works loose from worn Mounting fingers falls onto whoever is below, which is why the attachment gets checked rather than assumed.
Queues decide what is possible. A popular route has people within a metre in both directions, so the clean frame does not exist and the crowd becomes part of the record whether anybody wanted it.
How RawClip handles it
A continuous route with no pauses gives the selection very little to anchor on, so the bridges, ladders and the most exposed traverses are what survive. The worn angle and any fixed positions are combined, which is what gives a route a sense of progression.
