FAQ
Do I really need ND filters on a GoPro?
If you shoot outdoors in daylight and want smoother, more natural motion blur, ND filters help prevent overly fast shutter and “stuttery” footage.
How fast can I swap filters?
The magnetic system is designed for quick, tool-free swaps so you can react to changing light without stopping your shoot.
Can I stack filters?
Yes—up to 2 filters is recommended to avoid the edge becoming visible at ultra-wide / certain sensor modes.
Built for creators who shoot in the real world: fast exposure control, glare reduction, and a clean rig you’ll actually use on every shoot.

Sunglare?
Sun Shade to the rescue
When you're vlogging an adventure, trying to get that cinematic sequence or time laps, sun glare can often completely ruin the footage, leaving it void of contrast and color. That's where the sunshade comes in.
Durable
When the sun shade is closed, the Action Box Cine doubles as its own travel case.
Interchangeable
The sun shade is easily attached and detached, so when you don't need it just take it off.
Magnetic ND filters
Magnetic ND filters
Magnetic ND filters make changing filters effortless and enjoyable.
Motion Blur = Cinematic
There’s a reason the film industry relies on ND filters: they create a natural look by enabling motion blur. This technique helps achieve a cinematic quality in video, making your footage feel smooth and engaging.
How do ND's work?
ND (Neutral Density) filters reduce the amount of light entering the lens, helping to prevent overexposure in bright conditions. They enable a slower shutter speed for natural motion blur, allow for wider apertures to enhance depth of field, and maintain color accuracy.
Circular Polariser
The Action Box Cine features an easy-to-use external adjustment wheel for a pre-installed CPL (Circular Polarizer), perfect for reducing harsh glare on reflective surfaces like water or glass. Capture stunning contrast in every shot, transforming ordinary moments into extraordinary memories. Just keep in mind, it’s not ideal for low light conditions or wide-angle lens settings.
External Mounting
Mounted externally, the Action Box Cine lets you effortlessly attach all your favorite grips and mounts, eliminating the hassle of disassembling your rig just to change a battery or SD card.
