vivo X500 Pro series teases 4K 240fps video with custom Sony sensor

Four times the resolution at four times the frame rate
The X500 Pro's 4K 240fps capability represents a significant leap from typical smartphone video performance.

So vivo is putting a custom Sony sensor in these phones. How much of this is actually Sony's work versus vivo's?

Mimi

It's a co-developed sensor, which means both companies had a hand in the design. Sony manufactures the silicon, but vivo's Blueprint Imaging team shaped the specifications to fit what they wanted the phone to do. It's a partnership, not just a purchase.

Luke

Right, but we should be clear: we don't know the exact division of labor. "Co-developed" is a term that can mean anything from 50-50 collaboration to one company doing most of the work. The source doesn't break that down.

Mark

And the 4K 960fps recording—that's not actually captured by the sensor, correct?

Mimi

Correct. The sensor captures at lower frame rates, and then vivo's algorithms interpolate the frames in between. It's a software trick, but it's a legitimate one. The result is slow-motion video that looks like it was shot at 960fps.

Luke

Which is important to note because "4K 960fps" might make someone think the sensor is natively capturing that much data. It's not. The quality and smoothness of that interpolated footage is still an open question.

Mark

What about the dynamic range number—17EV. Is that good?

Mimi

Seventeen stops of dynamic range is quite good for a mobile sensor. It means the camera can hold detail in both very bright and very dark parts of the same frame. Most smartphone cameras max out around 12 to 14 stops.

Luke

Though we should note that dynamic range specs can be measured different ways, and we don't know exactly how vivo is measuring this. The number is impressive on paper, but real-world performance depends on how well the sensor and the processing pipeline actually use that range.

Mark

When do we actually get to see these phones?

Mimi

Later this month in China. That's all vivo has said so far.

Luke

And we don't have pricing, availability outside China, or any hands-on footage yet. The demo video vivo released shows the feature working, but we haven't seen independent testing.

  • The race to redefine what a smartphone camera can do has a new frontrunner: vivo's X500 Pro series promises 4K slow-motion recording at frame rates that most flagship phones cannot approach even at lower resolutions.
  • The tension lies in the gap between specification and reality — ultra-high frame rates like 480fps and 960fps at 4K are achieved through algorithmic interpolation, not pure hardware capture, raising questions about how the footage will hold up under scrutiny.
  • A custom Sony-co-developed sensor called the Phantom 900, with 17EV dynamic range and built-in 3-axis optical stabilization, gives the system a credible hardware foundation that goes beyond marketing language.
  • Vivo is managing anticipation deliberately, releasing camera details in stages ahead of a full launch later this month, keeping the conversation centered on imaging rather than price or availability.
  • The phones are landing into a market where 4K at 60fps is still the consumer norm, meaning the X500 series, if it delivers, could force a meaningful recalibration of expectations across the industry.

In the ongoing human pursuit of capturing reality with ever-greater fidelity, vivo is preparing to release two smartphones in China that blur the line between consumer device and professional cinema tool. The X500 Pro and Pro Max, built around a custom sensor co-developed with Sony, can record 4K video at 240 frames per second — a threshold that has long belonged to specialized equipment far beyond the pocket. This moment reflects not just an engineering milestone, but the quiet, relentless migration of extraordinary capability into ordinary hands.

Vivo is preparing to launch the X500 Pro and X500 Pro Max in China later this month, and the story is almost entirely about the camera. Specifically, the ability to record 4K video at 240 frames per second — a capability that has until now lived in specialized cinema equipment and high-end action cameras, not in devices that fit in a pocket.

At the center of the system is the Phantom 900, a custom sensor developed jointly by vivo's Blueprint Imaging team and Sony's imaging division. It is not an off-the-shelf component. The sensor delivers up to 17 stops of dynamic range — meaning it can hold detail simultaneously in the brightest highlights and deepest shadows of a frame — and includes three-axis optical image stabilization built directly into the hardware, a critical feature when shooting at extreme frame rates where even minor movement becomes visible.

Beyond the 4K 240fps headline, vivo has confirmed support for 4K at 480fps and 960fps as well. These upper tiers rely on frame interpolation and variable speed mapping algorithms that synthesize additional frames rather than capturing them natively, filling in the gaps between what the hardware actually records to create the appearance of ultra-high-speed footage.

Vivo has already released demonstration footage of the 240fps mode and has been deliberate in its pre-launch campaign, releasing imaging details ahead of full specifications. The strategy keeps the phones in the conversation while foregrounding the engineering work behind the camera system.

For context, most flagship smartphones top out at 4K 60fps, or 1080p when pushing to 240fps. Whether the X500 series delivers on its specifications in real-world conditions will become clear once reviewers have access — but the hardware foundation, at least on paper, represents a genuine step forward for mobile video.

Vivo is preparing to launch a pair of phones built around a camera system that pushes mobile video into territory most smartphones have not yet reached. The X500 Pro and X500 Pro Max, arriving in China later this month, will be able to record video at 4K resolution and 240 frames per second—a capability that until now has lived mostly in the realm of specialized cinema equipment and high-end action cameras.

The heart of this system is a custom sensor called the Phantom 900, developed jointly by vivo and Sony's imaging division. This is not a generic component; it represents a collaboration between the phone maker's Blueprint Imaging team and one of the world's largest camera sensor manufacturers. The sensor itself carries substantial specs: it can capture up to 17 stops of dynamic range—the technical measure of how much detail a camera can hold in both the brightest and darkest parts of a frame—and it includes three-axis optical image stabilization built directly into the hardware. That stabilization matters when you are shooting at extreme frame rates; without it, even the smallest camera shake becomes visible.

The 4K 240fps recording is the headline, but vivo is not stopping there. The company has confirmed that the X500 Pro models will also support 4K at 480 frames per second and 4K at 960 frames per second. These even more extreme frame rates are not captured natively by the sensor; instead, vivo's engineers have built algorithms for frame interpolation and variable speed mapping that synthesize the additional frames, creating the illusion of ultra-high-speed recording by intelligently filling in the gaps between what the hardware actually captures.

Vivo has already released a short video demonstrating the 4K 240fps slow-motion recording in action, giving potential buyers a concrete sense of what the feature can do. The company has been methodical in its teasing campaign, releasing camera details ahead of the full launch announcement. This piecemeal approach keeps the upcoming phones in the conversation and allows the company to emphasize the engineering work that went into the imaging system.

For context, 4K 240fps recording has been rare in consumer smartphones. Most flagship phones max out at 4K 60fps or, in some cases, 1080p at 240fps. The ability to capture four times the resolution at four times the frame rate represents a genuine leap in what mobile devices can do with video. The practical applications range from slow-motion sports footage to detailed capture of fast-moving objects, and the dynamic range specification means the camera should handle tricky lighting conditions without losing detail in highlights or shadows.

The X500 series launch is set for later this month, which means full specifications, pricing, and availability details should arrive soon. For now, the focus remains on the camera system—a signal that vivo believes imaging performance is the primary selling point for these devices. Whether the real-world video quality lives up to the specifications will become clear once reviewers get their hands on the phones, but the hardware foundation appears substantial.
