Trusted by professionals since 2019. Now even better.
For the discerning filmmaker, the direct-to-camera interview is a critical moment of connection. Achieving a genuine, natural eyeline to the camera is not just a technical challenge - it's essential to the story.
Since 2019, cinematographers, camera operators and production teams on high-stakes shoots have trusted the VoxBox Pro to deliver that connection with speed and reliability. Now, the VoxBox Pro MK3 evolves that legacy.
Choosing Your Interview Style:
Off-camera or down the lens?
There is no "correct" way to shoot an interview. The traditional off-camera eyeline remains a powerful tool for observational documentaries and specific narrative styles. It creates a sense of the audience looking at a conversation.
However, the visual language of filmmaking is evolving. Driven by the intimacy of social media, today's audiences are accustomed to being spoken to directly. The "down-the-lens" style breaks the fourth wall, turning an interview into a conversation with the viewer. It creates immediate intimacy, higher engagement, and a stronger emotional hook. The VoxBox Pro simply gives you the power to make that creative choice, perfectly.
Off-camera
Down-the-lens
How does it work?
The VoxBox Pro creates its connection using physics, not tech. It attaches to the front of your camera and utilises a clever system of precision mirrors (a beamsplitter and a secondary mirror) to fold the line of sight.
This means you achieve the perfect shot with no AI tricks, no extra cameras, no tablets, and no technology that can fail.
The Subject: Looks directly into the lens but sees a clear reflection of the interviewer's face in the glass.
The Interviewer: Sits to the side of the camera and looks through a portal in the box to see the subject.
The Result: The subject feels like they are having a natural face-to-face conversation, but on film, they are staring perfectly into the lens—resulting in the authentic, confident eye contact that cinematic storytelling demands.
Seamless integration. Effortless setup.
The VoxBox Pro MK3 seamlessly integrates into any professional camera setup.
No cumbersome baseplate, no special hardware. Its tool-free design sets up in under two minutes, saving critical time on set.
Standard rail mount
Mount it directly to your existing 15mm rail bars, just like fitting a matte box. Kit includes rail block with height adjustment (rails not included).
An optional 19mm rail block is available separately.
Light stand mount
A standard 3/8ths inch threaded hole on the unit allows it to be attached to standard grip accessories.
The included 16mm adaptor allows easy mounting to a light stand - ideal if you don't have rails or prefer this alternative mounting option.
Four interviewer positions. Built for real-world locations.
The VoxBox Pro is designed for the kinds of spaces filmmakers actually walk into - cramped offices, awkward corners, and rooms that were never meant for filming. With four possible interviewer positions around the unit, you can adapt instantly to whatever layout you’re given.
And for solo shooters, it’s a game-changer: the camera operator can conduct the interview directly while monitoring the shot, without breaking the subject's connection.
Upgrading from the MK2? New features explained
Every element of the VoxBox Pro MK3 has been re-engineered from real-world feedback by working cinematographers.
A wider perspective, the same perfect eyeline
The MK3's redesigned system now accommodates wider lenses up to 28mm*, allowing for more environmental context without sacrificing the intimate, down-the-barrel eyeline.
*Test conducted with Sony G-Master 24-70mm; Sony FX9 full frame (6K).
Solves handle and rail clearance issues
The MK3 is designed to fit your camera package, not fight it. The redesigned housing effectively solves the clearance conflict with the Sony FX6 top handle, allowing for seamless rigging even when using short-barrel or pancake lenses.
Additionally, this new shape provides clearance for longer support rods. You no longer need to ensure your rails sit shorter than the front of the lens, giving you more freedom with your baseplate setup. Whether it’s handle placement or rod length, the MK3 removes the friction for a fast, adaptable build.
Integral filter tray
The VoxBox Pro MK3 integrates standard 4x4" and 4x5.65" PV filter support - so you never have to compromise your creative vision when filming interviews.
A dual-size filter tray is included, allowing you to craft the look you want right at the lens - ND, diffusion, Soft FX - whichever your scene demands.
It’s one less accessory to rig, and one more reason cinematographers reach for the VoxBox Pro on every shoot.
Need a teleprompter?
The VoxBox Pro MK3's versatility now extends to large-screen prompting. The included tablet holder clips on instantly, transforming your eyeline tool into a professional teleprompter.
We’ve redesigned the mount to be more robust, easily accommodating larger devices - including the 13-inch iPad Pro.
This allows you to run scripts, patch in a remote director, or conduct video calls, all while the talent maintains a flawless, direct-to-camera connection. It’s the perfect solution for hybrid shoots and presenter-led content.
Engineered for the real world
Designed and built in Britain, the VoxBox Pro MK3 is more than a piece of kit. It’s the bridge between your story and the audience.
Engineered from a carbon fibre–infused polymer, the MK3 achieves the perfect balance of strength and refinement — durable enough for the most demanding productions, from high-end documentaries to premium branded content and feature interviews, where quality, speed, and reliability matter most.

3mm enclosed mirror for extra protection

While entry-level kits often cut corners by shipping in flimsy cardboard or basic nylon bags - if they provide a case at all - we believe storage is as critical as the product itself. Professional gear lives on the road, and equipment is only useful if it survives the journey.
That's why the VoxBox Pro MK3 ships standard in a rugged, IP67-rated hard case. It is engineered to withstand the rigors of airline travel and the demands of the toughest production environments.
Inside, a custom-cut, high-density foam insert perfectly cradles the parts. It is designed to absorb shock and impact, preventing movement and ensuring every component stays exactly where it belongs during transport.
The optical core of the VoxBox consists of two critical elements: the high-grade beamsplitter glass and a side mirror. The beamsplitter glass remains fitted within the main unit, while the side mirror is stored in a dedicated recess in the case lid.
This design isolates and secures each optical component individually, protecting these delicate elements during transport and ensuring the system arrives ready for use.

Real results, not just promises
You’ve read the specs - now hear the reality.
The only opinion that truly matters is the one behind the camera. Here is the unvarnished truth from the DPs and filmmakers using the VoxBox Pro in the field every day.
"We spent six months planning this film for The York Policy Engine and the University of York. It wasn't just about capturing footage; it was about translating complex academic and policy concepts into a stunning, engaging narrative. When you have that much creative thinking on the line, the kit just has to work.
The VoxBox Pro MK3 was invaluable on set. Directing non-actors and experts can be challenging, but the VoxBox allowed our contributors to deliver their lines with confidence and maintain that crucial connection with the audience 'down the lens.'
Ultimately, it’s about the outcome: the client was absolutely delighted with the creative direction and the end results. I highly recommend the VoxBox for any shoot where you need to bridge the gap between technical execution and creative vision.
Seeing months of meetings and creative planning finally come to life on screen was a joy, and the VoxBox played a massive part in making those days run smoothly. Highly recommended."

"On a busy shoot, my kit needs to be second nature - I can’t get bogged down in the 'meccano' of camera rigging. For this project, relying on my Sony mirrorless setup, the VoxBox Pro MK3 became the missing piece of the puzzle.
It bridged the gap between scripted teleprompting and natural interviews perfectly. The unit integrated seamlessly via 15mm rails, allowing us to mount an iPad for teleprompting and then instantly switch to the director for engaging 'down-the-lens' conversation. It was lightweight, fast, and elevated the production value significantly without compromising our speed or the camera's footprint."
— Dan Mears, Freelance Director of Photography
"We used the VoxBox Pro MK3 on a shoot for an international hotel brand, filming across several prestigious hotel locations in and around London. The schedule was fast-paced, with multiple set-ups each day, so speed and reliability were absolutely critical.
The VoxBox Pro MK3 was incredibly quick to rig and became an invaluable part of the kit. That efficiency gave us more time to focus on performance and storytelling rather than technical compromises.
Our contributors were hotel staff, speaking directly to fellow colleagues, so achieving a genuine sense of connection through the lens was essential. The VoxBox Pro proved to be the ideal solution, allowing contributors to engage naturally and confidently with the camera. The result was a much stronger, more authentic connection on screen.
It worked superbly and is now a go-to tool for this kind of interview setup."

"For the FIFA Club World Cup Technical Study Group, direct engagement was critical. We needed experts to deliver complex tactical analysis while maintaining perfect eye contact with the viewer.
The VoxBox Pro MK3 was the perfect solution. It balanced effortlessly on our Sony FX9 rails, and the tool-less setup allowed us to maintain a fast, efficient workflow in the hotel-based studio. It’s solid, reliable, and essential for high-end interviews."

Product Comparison
VoxBox Air vs MK3 — What’s the Difference?
The VoxBox Air and the VoxBox Pro MK3 share the same core principle — delivering natural, down-the-lens eye contact in a reliable package — but they’re built for different kinds of productions, user needs and budget.
Designed for portability and speed, the Air is the lightweight option for run-and-gun crews, one-person operators, and fast turnaround shoots. It’s ideal when you need minimal setup, easy travel, and a smaller footprint without sacrificing the signature VoxBox experience.
The MK3 is the more robust model. With greater lens compatibility and a heavier-duty build, it’s designed for higher-end productions and environments where the unit stays built and ready to roll. It offers more flexibility for demanding shoots and a more rugged workflow.

VoxBox Pro MK3 FAQs
Will it attach to my camera rig?
Standard 15mm rails are recommended for optimal use. You will also need a medium/heavy duty tripod to support the front weight of the main unit.
Sold separately is a 19mm rail block.
Is it supplied with 15mm rods?
No, you should already have 15mm rails to mount the VoxBox Pro MK3. Ideally your rails should not extend much past the front of the lens.
Sold separately is a 19mm rail block.
If I don’t have rails or if I am using a small camera or a DSLR?
The VoxBox Pro comes with a 16mm receiver adaptor. This screws onto the base of the VoxBox, allowing you to attach it to a standard light stand. The unit can then be positioned in front of the camera lens.
Does it work with FX6?
Yes. Even with short barrel lenses, a cutout in the VoxBox body will support the FX6's top handle.
How heavy is the VoxBox Pro?
The VoxBox Pro main unit is about 1.9kg (without tablet adaptor or side mirror).
Do the mirrors adjust for different interviewers?
The side mirror can be titled for interviewer comfort. If you are not using the side mirror, simply set the height of the camera to match the eye-level of the interviewer (as you would a standard off-camera interview) and frame the subject.
Does the beamsplitter glass give any loss of light or colour shift?
You will lose less than 1 stop of light through the glass. This is not a problem for most cameras. The glass ‘warms up’ the image slightly, which can be corrected in post-production if necessary.
What’s the widest focal length I can use?
On a full-frame sensor, around 28-30mm is the widest before the edges of the VoxBox Pro are visible in the frame. This figure depends on many factors such as lens design and how close the front of the lens is to the VoxBox Pro's beamsplitter glass.
What is the diameter of the hole on the box?
The opening at the back of the VoxBox Pro (where the lens is positioned) is 140mm (5.5 inch). Doughnuts are supplied to fit on various lenses to eliminate light.
How do I clean the beamsplitter glass?
Make sure all dust and grit is brushed or washed from the glass. Do not rub it when dry. When clear of dust and grit, the surfaces may be cleaned using any soft cotton based cloth. Man-made fibres will eventually damage the surface. Dabbing the surface with a damp soapy cloth to remove dust and grit is safe. The glass can then be polished. Non-greasy window cleaning products used in conjunction with a cotton cloth should be safe, once all grit has been removed
Which tablets work with the VoxBox Pro?
The included adjustable tablet holder will accept any device up to 13 inch iPad Pro. Max size between the clamps is 227mm (8.9 inch).
Note that due to the size of the opening at the side of the unit, some of the tablet screen may be cropped.
Which teleprompting software works with the VoxBox Pro?
There are many free and paid-for Teleprompter software applications available. We recommend applications with the following features:
1. Flip mirrored text horizontally
2. Text justification (recommended if using a tablet bigger than the beamsplitter glass can acommodate).
