Introduction: The Evolution of 360 Action Cameras

Remember when capturing a moment meant pointing a camera in one direction and hoping you didn’t miss anything? With 360-degree action cameras, that’s no longer a problem. You press record, and the entire scene—front, back, up, down—is captured in one seamless sphere. Among the leaders in this space, Insta360 has consistently pushed the envelope, and their latest releases, the Insta360 X3 and Insta360 X4 8K 360 action camera, represent a significant leap forward in immersive video technology.

As someone who’s tested both models side-by-side—from mountain biking trails to underwater snorkeling trips—I’ve seen firsthand how these cameras transform storytelling. Whether you’re a content creator, adventure seeker, or just someone who wants to relive memories in full 360 glory, choosing between the X3 and X4 can feel overwhelming. That’s why I’ve put together this detailed comparison. We’ll dive into specs, real-world performance, usability, and more, so you can decide which model fits your needs—without the marketing fluff. Let’s explore how the Insta360 X3 vs Insta360 X4 8K 360 action camera specs truly stack up.

Sensor and Resolution: The Heart of the Image

X3: Dual 1/2″ Sensors with 5.7K Max Resolution

The Insta360 X3 features dual 1/2″ sensors, each capturing 18MP stills and up to 5.7K resolution at 30fps for 360 video. That might sound impressive on paper, but in practice, it’s the baseline for modern 360 cameras. The 5.7K output is great for social media and standard viewing, especially when you reframe shots in post using Insta360’s excellent editing app.

One thing I appreciated during a recent hiking trip was how well the X3 handled dynamic scenes. Even when I was moving quickly through a forest with dappled sunlight, the camera managed to retain decent detail in both shadows and highlights. However, in low-light conditions—like twilight at the summit—the smaller sensors started to show their limits. Noise crept in, and colors became less vibrant.

Tip: If you’re shooting in variable light, use the X3’s “Auto Exposure” mode with caution. Manually adjusting exposure in the app before filming can prevent blown-out skies or underexposed faces.

X4: Upgraded 1/1.7″ Sensors with True 8K 360 Video

Now, the Insta360 X4 8K 360 action camera takes things to another level. It sports dual 1/1.7″ sensors—larger than the X3’s—and can record true 8K at 30fps (7680×3840). That’s nearly double the pixel count, meaning you’re capturing far more detail, especially when zooming in or reframing during editing.

I tested this during a beach day with friends. When I later edited the footage, I could clearly see individual grains of sand on someone’s foot and read a distant sign across the bay—something impossible with the X3. The larger sensors also mean better light gathering, which translates to superior low-light performance. In a dimly lit cave dive, the X4 produced cleaner, less noisy footage compared to the X3, which struggled with grain.

Another standout: the X4 supports 8K at 24fps and 5.7K at 60fps, giving you more flexibility. For slow-motion shots of waves crashing or skate tricks, the 60fps option is a game-changer. The X3 maxes out at 5.7K/30fps or 4K/60fps, which is good but not as future-proof.

Pro Tip: Use the X4’s “HDR Video” mode in high-contrast scenes (like sunsets). It preserves more detail in both shadows and highlights, though it requires a bit more processing time in the app.

Video Quality and Stabilization: Smoothness Meets Sharpness

FlowState Stabilization: A Step Forward

Both cameras use Insta360’s proprietary FlowState Stabilization, but the X4 has a significant edge. The X3’s version is solid—great for casual use—but I noticed slight wobble when mountain biking on rocky trails. It wasn’t bad, just not buttery smooth.

The X4, however, uses an upgraded stabilization algorithm that leverages its more powerful processor. During the same trail ride, the X4’s footage looked like it was shot on a gimbal. Even when I hit a bump or turned sharply, the horizon stayed level. This is thanks to 360 Horizon Lock, which keeps the horizon perfectly level regardless of how you rotate the camera—a feature the X3 lacks.

Example: I attached the X4 to my bike helmet and rode through a winding forest path. When I later reframed the shot to follow my handlebars, the view remained rock-steady. With the X3, the same shot had a slight “bobble” effect when I hit uneven terrain.

Dynamic Range and Color Science

Color reproduction is another area where the X4 shines. It uses a newer image processing chip that delivers more natural skin tones and vibrant yet accurate landscapes. The X3 tends to oversaturate greens in forests, which can look artificial. The X4, by contrast, renders foliage more realistically.

Dynamic range is also better on the X4. In mixed lighting—say, a campfire at night with people in the foreground and stars above—the X4 captures both the warm glow of the fire and the subtle starlight without clipping highlights or crushing shadows. The X3, while capable, often requires post-processing to balance these extremes.

Tip: Shoot in the X4’s “Log” mode if you plan to color-grade in post. It preserves more dynamic range, though it looks flat straight out of the camera. The X3 doesn’t offer a Log mode, limiting your grading options.

Audio Quality: Small but Noticeable Differences

Both cameras have built-in microphones, but the X4 adds wind noise reduction and a wider frequency response. In a windy coastal shoot, the X4’s audio was clearer, with less distortion. The X3’s mics pick up more ambient wind, which can be distracting.

Neither is ideal for professional audio, but if you’re recording voiceovers or ambient sound, the X4 is the better choice. For best results, consider using an external mic (both support USB-C audio input).

Design, Build, and Usability: Form Meets Function

Size and Ergonomics

The X3 is compact and lightweight—about the size of a small flashlight. I’ve carried it in my pocket on hikes, and it never felt bulky. The front touchscreen is responsive and makes framing shots easy, even with gloves on.

The X4 is slightly larger and heavier (by about 20%), but still highly portable. The bigger body accommodates the upgraded sensors and battery, and it feels more substantial in the hand. The 2.5-inch touchscreen (up from the X3’s 2.29-inch) is a welcome improvement, making it easier to navigate menus and preview footage.

Tip: If you plan to use the camera with a selfie stick or drone, the X4’s weight difference is negligible. But if you’re carrying it all day, the X3’s smaller size might be preferable.

Durability and Water Resistance

Both are IPX8 rated, meaning they can be submerged up to 10 meters (33 feet) without a case. I’ve taken both snorkeling and had no issues. However, the X4’s redesigned lens covers are easier to clean and less prone to fogging. After a dive, I could wipe off saltwater quickly, whereas the X3’s covers sometimes trapped moisture.

For deeper dives (beyond 10m), you’ll need a dive case. The X4’s case is slightly thicker, offering better protection, but both are reliable up to 50m.

Battery Life: A Major Upgrade

Battery life is where the X4 truly outperforms. The X3 has a 1800mAh battery, which lasts about 81 minutes when recording 5.7K/30fps. The X4’s 2290mAh battery delivers 135 minutes of 5.7K recording—or 75 minutes at 8K. That’s a huge difference for long shoots.

I tested this during a full-day ski trip. With the X3, I needed to swap batteries twice. The X4 lasted the entire day on a single charge, even with 8K recording and frequent app usage. Plus, the X4 supports fast charging (50% in 30 minutes), while the X3 charges slower.

Pro Tip: Carry a power bank. Both cameras support USB-C charging, so you can top up on the go.

Editing and Software: The Post-Production Experience

Insta360 App: Smoother and Faster

The Insta360 app is central to both cameras, but the X4 benefits from optimizations for 8K footage. Editing 8K videos on the X3’s app can be sluggish, especially on older smartphones. The X4’s app handles 8K clips more smoothly, with faster preview rendering and export times.

Both apps offer AI-powered editing tools like auto-reframe, object tracking, and “FlashCut” (which auto-edits clips into a montage). The X4’s AI is more accurate, especially when tracking fast-moving subjects. In a skateboarding video, the X4’s app followed the board perfectly, while the X3 occasionally lost focus.

Desktop Editing: More Power, More Options

For professional editors, the X4’s 8K files offer more flexibility. You can crop, pan, and zoom without losing detail. The X3’s 5.7K files can feel limiting if you’re creating 4K output with heavy reframing.

Both support Apple ProRes (X4 only) and H.265 encoding. ProRes files are larger but retain more color data, ideal for grading. The X3 only supports H.264 and H.265.

Tip: Use the X4’s “Single-Lens Mode” to extract 4K flat video from one lens. Great for traditional vlogging without 360 effects. The X3 offers this too, but at lower resolutions.

Accessories and Ecosystem: Expand Your Creativity

Mounts and Add-Ons

Both cameras use the same accessory ecosystem, which is a big plus. You can use X3 mounts, cases, and filters with the X4 (and vice versa). This is great if you’re upgrading—no need to replace your gear.

Popular accessories include:

• Invisible Selfie Stick: Disappears in footage, making it look like you’re floating.

< Drone Mount: For aerial 360 shots.

• 360 Lens Protector: Essential for protecting the lenses during rough use.
• Mic Adapter: For connecting external mics (X4 supports higher bitrates).

Special Features: What Sets the X4 Apart

The X4 introduces several new features not available on the X3:

• 8K Timelapse: Create hyper-detailed time-lapses.
• Pre-Recording: Captures 15 seconds before you hit record—great for action shots.
• Voice Control: “Start recording” or “Take a photo” hands-free.
• AI Highlight Detection: Automatically tags exciting moments in your footage.

I used the pre-recording feature during a surfing session. I didn’t have time to hit record when a big wave came, but the X4 saved the 15 seconds before—capturing the entire ride. The X3 doesn’t have this.
