Razer Kiyo Pro Ultra Review: It Comes So Close to Greatness

The 4K streaming-optimized webcam can deliver excellent quality compared to current competitors, but it can also be just a little too glitchy.

My initial reaction to the Razer Kiyo Pro Ultra’s video was «Wow! Finally a webcam as good as a compact vlogging camera.» My reaction after trying to adjust the settings, especially when using it with a third-party application, was «I’m going to reach through my screen and punch you now.» Seriously: Razer’s Synapse software is the only thing preventing this $300 (£300, AU$500) 4K webcam for streamers and power videoconferencers from getting an Editors’ Choice award.

Synapse is the only way to control most of the settings, so it can make or break your experience. If you don’t need to change settings besides zoom, focus or white balance that often (they’re available via the Windows driver), then you’ll probably be OK. And even Synapse 3 doesn’t work on the Mac, so the webcam’s not well suited for that platform.

Like

  • Excellent quality and performance
  • Nice built-in lens cover design
  • Has a relatively large number of adjustable settings which compensate for issues other cameras have

Don’t Like

  • Synapse control of camera is glitchy and the camera occasionally hangs when changing settings
  • You can only change settings when Synapse has exclusive control of the camera

The Kiyo Pro Ultra’s closest competitor would have been the Elgato Facecam Pro, which no longer seems to be available anywhere despite shipping in November 2022. (It used a previous generation of the Sony Starvis sensor, and it’s always possible that it’s being reworked with the newer sensor.) 

That camera supported 4K at 60fps compared to the Razer’s 30fps (at 1080p and lower it can do 60fps), but otherwise the Razer has a lot of the same strengths, including manual exposure controls, user presets and other settings which can help you tweak the quality of your output, such as MJPEG quality (for streaming at 1440p or 4K) and the ability to meter off your face in autoexposure mode (important if you’re off center) and lens distortion compensation. 

While it looks similar to the rest of its Kiyo siblings, the Pro and the X (on our list of the best webcams we’ve tested), it has something I’ve wanted for a while: a built-in lens cover. Razer cleverly incorporated it as an iris that closes when you rotate the outer ring.

Top marks for quality and performance

When it’s good, the Kiyo Pro Ultra is great. It incorporates a 1/1.2-inch Sony Starvis 2 sensor, which is a just bit smaller than the 1-inch sensor in compact vlogging cameras like the Sony ZV-1 but loads bigger than the sensors in other webcams, with a good size f1.7 aperture. 

The larger sensor and aperture means it shows perceptible depth-of-field blur. It doesn’t have as wide a field of view as many webcams, only up to 82 degrees (72 degrees with distortion correction on) rather than 90 or more, which could affect its suitability for your needs.

The Ultra displays excellent tonal range for what it is, though it falls short in handling bright areas. It needs some software tweaking for that, I think. It has the typical HDR option, but in a backlit shot with a properly exposed foreground (as well as without), it didn’t help clip the overbrightness in the back. There are toggles for both dark and light rooms, but neither seemed to make a perceptible difference. I’ve had other cameras handle it better. 

It meters properly, for the most part. Center metering works best if you’re in the center — face metering overexposes oddly without tweaking the exposure compensation, otherwise. But if you lean to the side, face metering keeps it from spiking when it sees your black chair instead of your face. White balance is very good as long as you’re not in too dark an environment. Even then it’s not bad. Nor does it lose a lot of color saturation. 

You can toggle a couple of noise reduction settings and they do make a significant difference in low light. The distortion compensation makes a visible difference as well. 

Standard autofocus is meh, just like all the other webcams. But there are several settings to mitigate the frequent hunting, which other webcams don’t have. Face autofocus does a good job of keeping it from hunting when you move your head, and there’s a «stylized lighting» setting which helps the AF system lock when the lighting might otherwise confuse it. 

The camera handles some of the image processing that might otherwise be sent to the PC, notably the MJPEG compression of the stream you’re sending, and you can set how aggressively it compresses either automatically or on a performance-to-quality continuum. 

Still needs some baking

Unfortunately, it’s still just a little too glitchy and the software limits it unintentionally. You can’t access any of the settings in Synapse — most notably resolution/frame rate and manual exposure (ISO and shutter speed) — unless camera preview is enabled. And Windows only allows one application to access a camera at a time. 

So, for example, if you’ve accidentally left the resolution at 4K but you need it to be 1080p in OBS, to change it you have to first deactivate the camera in OBS — thankfully, OBS has that option, but Nvidia Broadcast doesn’t. Then jump over to Synapse, turn on preview, change the resolution, turn off preview, jump back to OBS and reactivate the camera. And resolution, among other settings, doesn’t seem to be saved as part of the profiles you can create.

Doing it once isn’t that much of a problem. After the 10th time in an hour it gets old. 

It’s also complicated by the occasional failure of settings to kick in, which sometimes forces you to loop back through that activate-deactivate cycle: Why does my adjusted exposure not look adjusted? Do I have to kick it to get autofocus to kick in? The preview in Synapse isn’t always accurate, though that’s not unique to Synapse, but it means you can’t assume your adjustments there will be correct. Synapse also froze several times while I was trying to swap between profiles.

Almost every other reasonable webcam utility allows you to change settings while viewing within the application you need them for. Yes, sometimes a few are disabled (because Windows), but at least they’re not all unavailable. It’s possible that all these issues can be ameliorated with firmware and software patches, but I have learned never to assume that just because they can be that they will be.

The Razer Kiyo Pro Ultra is a capable webcam that just needs some software and firmware polish before I’m comfortable considering it a reliable, consistent performer.

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
