Thirty years on set, and the profession has changed more in the last decade than in the twenty years before. The electronic gimbal, motion control, FPV drones, LED walls: each of these technologies has altered the way we prepare a shoot, read a script, anticipate a camera move. What hasn’t changed is the physics. And the sense of movement.
What technology has actually changed on set
The question isn’t whether these tools are useful — they are. The real question: what they demand of us.
An electronic gimbal like the DJI Ronin 2 or the Ronin 4D doesn’t replace the operator. It amplifies their decisions. When an ARRI ALEXA 35 camera with a Zeiss Supreme lens exceeds 15 kg on the system, every micro-gesture gets amplified or corrected by the stabilisation algorithms — but the quality of the movement, its dramaturgy, its timing, that remains in the crew’s hands. The gimbal has no narrative sense. We do.
What has truly changed: upstream preparation. Where a manual tracking shot was adjusted in rehearsal on set, a motion control sequence is programmed the evening before, sometimes two days ahead. You need to master the software, understand the axes, validate the trajectory with the cinematographer. It’s no longer just grip work — it’s multi-level technical coordination.
How the electronic gimbal has transformed daily work
Electronic stabilisation has opened up unprecedented movement possibilities. Moves that were once reserved for the Steadicam — pursuit shots in interiors, following through a stairwell, tracking in confined spaces — are now achievable with a gimbal operator and a well-configured rig.
But this apparent freedom conceals increased demands. Configuring a DJI Ronin for a heavy head requires knowledge of motor parameters, follow curves, and control modes. On productions like those we’ve done for Prime Video or HBO, you don’t arrive on set with approximate settings. The camera must be perfectly balanced before you even discuss artistic intent. (And trust me, a first AC waiting on their focus pull while you rebalance an 18 kg head — that kills the mood.)
“The gimbal is a formidable tool when you know what you’re after. Otherwise, it’s just expensive equipment poorly used.” — Fabrice Mignot
The most demanding shoots still combine gimbal and dolly. The dolly guarantees consistency over long distances. The gimbal takes over for finishing touches or impossible spaces. Two tools, two logics — it’s the key grip who decides which serves the image at which moment.
Motion control: when the camera becomes programmable
The Bolt Junior, the Milo, the Kira: these motion control systems were long reserved for commercials and post-production visual effects. Today they appear on high-end series, music videos, and ambitious features.
The principle is simple to describe, complex to master. You programme a camera move on a software interface, the robot executes it identically — a hundred times, a thousand times if necessary. For a stop-motion scene, for a green screen composite, for multiple takes with different lighting: exact repeatability is what human grip work cannot offer.
On a feature we prepped with Agat Films, the motion control operator needed twenty-two identical takes for a complex composite. Twenty-two. No manual tracking shot would have held to 0.3 degrees across all of them. That’s where the robot wins — not on intent, on raw precision.
What this changes for the grip: you need to understand movement files, know how to read an animation graph, dialogue with the motion control operator. It’s not a separate role. It’s an extension of ours. The grip crew configures the rails, validates safety margins, supervises the mechanical installation. The software is another pair of hands you need to learn to direct.

FPV drones: an aerial grip tool, not a gadget
FPV drones have changed the approach to action shots. Where you once set up a crane, sometimes a camera car, sometimes a helicopter with a gyro-stabilised head, you now place a pilot with goggles and a drone capable of flying through fifty-centimetre gaps.
What many productions underestimate: a cinema FPV drone is not a recreational drone. Systems used in professional shoots carry lightweight but precise cameras, and their piloting requires coordination with the entire set crew. Safety distance, flight corridor, coordination with the AD, DAS validation for exterior shoots: regulations apply fully.
The grip’s role in these sequences is to ensure the space is secured. That cables and ground equipment don’t pose a danger. That transitions between the drone and other devices — a dolly, a crane — are prepared with precision. The drone doesn’t replace ground-based grip equipment. It complements it for specific moves that nothing else can reproduce.
LED walls and virtual production: what it changes for grip work
Virtual production shoots with LED walls fundamentally alter the relationship between grip equipment, lighting, and set design. On a traditional set, the key grip works within a defined space — rails, dollies, and cranes are adapted to the actual configuration of the location. In virtual production, that space is partially virtual. The constraints change entirely.
The camera must remain within a precise zone for the LED wall’s perspective to match the rendered image. Camera tracking — a system that communicates the camera’s position and orientation to the 3D engine in real time — is integrated directly into the grip equipment. The head, the crane arm, the dolly become elements of a larger digital system.
Understanding tracking constraints. Not introducing parasitic vibrations that would disrupt synchronisation. Working in close coordination with the virtual production team. The mesh between disciplines — grip, VFX, lighting — is total, and it represents a genuine shift in posture for crews accustomed to working in silos. The article on the impact of LED walls on grip work explores these constraints in detail.
What will never change: the sense of movement
I’m often asked the question: “Will these technologies replace grips?” The short answer is no. The complete answer deserves a few lines.
“What has changed in 40 years — and what will never change: the sense of movement.”
A dolly on rails, a 10-metre crane, a motion control robot costing €80,000: none of these tools decides alone what emotion a shot should provoke. What makes the difference on an HBO or Netflix shoot is the ability to read a scene, to anticipate an actor’s dynamics, to propose to the cinematographer a move that serves the story. No algorithm replaces that.
The physics is still there. A digital camera with a lens and cage assembly weighs between 15 and 25 kg. Rails must be laid on sometimes unforgiving surfaces — a forest floor, a spiral staircase, a rooftop. Safety remains a human responsibility, non-delegable. A poorly secured crane arm remains dangerous, regardless of how sophisticated the control system is.
What technology actually demands: a more complete grip. Capable of handling a wrench and reading a trajectory file. Capable of laying track by hand and understanding why motion control is preferable for a given take.
Adapting without losing yourself: the skills that matter today
Training is evolving. Specialised technicians are emerging — motion control operators, certified drone pilots, virtual production technicians. These are professions in their own right, and that’s a good thing. Specialisation enables depth.
For a key grip, the question isn’t mastering everything. It’s knowing in which context to call on which expertise, and being able to dialogue with these specialists from an informed position. No need to become a trajectory programmer. Need to understand what the robot can do and what it can’t.
The priority training areas today:
- Understanding the basics of motion control (axis logic, movement files, safety margins)
- Knowing how to configure and balance a cinema gimbal with heavy loads
- Mastering the regulatory constraints of drones on shoots (DGAC, DAS, zones)
- Understanding camera tracking and its mechanical implications in virtual production
The rest — reading a set, anticipating the unexpected, managing a crew under pressure — that’s learned over the years. And no technology can accelerate that.

FAQ — Technology and the grip profession
Does technology (gimbal, motion control) replace the grip?
No. These tools augment the crew’s capabilities, but they don’t replace technical judgement or the dramaturgical reading of a shot. A gimbal doesn’t decide the timing of a move. A motion control robot doesn’t know that an actor has slightly changed their path. The grip remains the guarantor of coherence between artistic intent and mechanical execution.
Is specific training required to work with motion control?
Yes, without hesitation. Systems like the Bolt Junior or the Milo require training in trajectory programming software and knowledge of safety protocols specific to this equipment. On professional shoots, this typically means a dedicated motion control operator, with whom the key grip works in coordination for installation and safety. It’s not a role you improvise on the first morning of a shoot.
What is the difference between an FPV drone and a crane for an aerial shot?
An FPV drone offers mobility and the ability to navigate confined spaces that no crane can reproduce. The crane remains superior for slow, precise movements, long controlled amplitudes, and situations where image stability takes priority over trajectory freedom. Both coexist on high-level sets — the choice depends on the nature of the shot and production constraints.
How do LED walls change grip work?
The main change is the playing zone constraint. In virtual production, the camera must stay within a precise volume for the LED background’s perspective to remain coherent. This limits movement amplitudes and requires close coordination with the tracking system. Grip equipment must be selected for its precision and low parasitic vibration levels — a dolly that rattles on its bearings is a dealbreaker.
Is the grip profession accessible without mastering all these technologies?
At the start of a career, no — it’s impossible to have complete expertise across all these systems. Progression happens through gradual specialisation. What matters in the short term: mechanical fundamentals, set safety logic, and a genuine capacity for rapid learning. Specialised training (motion control, virtual production) comes later, through projects. I’ve seen very solid technicians on the basics become formidable motion control operators in eighteen months — provided they put in the work.
