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.

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.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
