With its Pixel 8 and Pixel 8 Professional smartphones, Google is bringing its huge weapons to the battle for smartphone photograph and video management. Amongst greater than a dozen notable enhancements coming to the Android telephones is a software referred to as Video Increase that makes use of AI processing on Google’s server-packed knowledge facilities to dramatically improve picture high quality.
While you first shoot a video, you may have only a 1080p preview model. However throughout a pair hours or so for importing and processing, Google makes use of new synthetic intelligence fashions too huge for a smartphone to enhance shadow element, cut back pesky noise speckles and stabilize the video. Meaning Google’s Night time Sight expertise, which in 2018 set a brand new customary for smartphone images taken in dim and darkish situations, has now come to video, too. Or at the very least it’ll when Video Increase ships later this winter.
“Night time Sight means one thing very huge to us,” stated Isaac Reynolds, the lead product supervisor answerable for the Pixel cameras. “It’s the finest low-light smartphone video out there, together with any telephones that may have not too long ago come out,” he stated in an unsubtle dig at Apple’s iPhone 15 fashions. However Video Increase improves daytime movies, too, with higher element and smoother panning.
Reynolds spoke throughout an unique deep dive interview in regards to the new photograph and video expertise within the $699 Pixel 8 and $999 Pixel 8 Professional, unveiled Wednesday. He detailed the brand new {hardware} Google calls twin publicity that makes Night time Sight video doable, together with a spread of latest Pixel pictures advances: higher-resolution images, higher lenses, a brand new app with superior pictures controls, a capability to create a bunch photograph the place all people is smiling and an Audio Magic Eraser to scrub up the sound in a video.
Digicam skills are key to smartphones, however particularly to Google’s Pixel telephones. They’re gaining market share however stay comparatively uncommon, accounting for simply 4% of North American telephone shipments within the second quarter. Good images, bolstered by years of computational pictures work, are arguably the Pixel line’s strongest promoting level.
However the Pixel telephones’ video has been weak when there’s not a lot mild. Enhancing that, even when it takes a serving to hand from Google’s servers, is essential to creating a Pixel telephone value shopping for.
“The place we actually needed to make an enormous distinction this yr was video,” Reynolds stated. Video Increase is “probably the most thrilling factor that I’ve executed in years.”
This is an in depth take a look at how Google is attempting to wring higher images and movies out of its Pixel 8 telephones.
How Pixel 8 Video Increase works
Many developments had been essential to make Video Increase doable.
On the basis is a more moderen picture sensor expertise within the Pixel 8 most important digicam referred to as twin conversion acquire that improves picture noise and dynamic vary — the power to seize each shadow and spotlight particulars. Google refers to its method as “twin publicity,” however not like standard HDR (excessive dynamic vary) expertise, it does not mix a number of separate photographs.
As an alternative, the twin conversion acquire expertise is ready to concurrently seize particulars from each low-light and vibrant areas of a scene pixel by pixel, then mix one of the best of each. The outcome: “Whether or not it is a high-contrast scene or a low-light scene, you are going to see dramatically higher efficiency versus the Pixel 7 and Pixel 7 Professional,” Reynolds stated. “You do not have to surrender the dynamic vary. Meaning much less underexposure, which suggests much less shadow noise.”
Subsequent is the brand new Tensor G3 processor, the third technology of Google’s Pixel telephone processors. The G3 has extra built-in Google circuitry for AI and picture processing than final yr’s G2, and Google makes use of it to supply two movies. One is the 1080p preview model you may watch or share instantly.
The opposite is the Video Increase model that is uploaded to Google for extra modifying. The G3 preprocesses that video and, for every body, provides as much as 400 metadata components that characterize the scene, Reynolds stated.
The final Video Increase step takes place in Google’s knowledge facilities, the place servers use newly developed algorithms for noise discount, stabilization and sharpening with low-light imagery. That processed video then replaces the preview video in your telephone, together with a 4K model, if that is the decision you initially shot at.
Reynolds defends the video’s knowledge heart detour as worthwhile.
“The outcomes are unimaginable,” he stated. Moreover, folks prefer to reminisce, revisiting a second via images and movies hours later, not simply months or years later. “I do not assume there’s any draw back in any respect to ready a few hours,” he stated.
It might be well worth the wait, however the wait additionally is perhaps longer than only a couple hours to pump gigabytes of video to Google. In case you’re away from house Wi-Fi, you is perhaps anxious about blowing via your plan’s cellular knowledge cap. And while you’re at house, you is perhaps among the many thousands and thousands of individuals whose broadband does not truly provide quick add speeds.
Extra megapixels on Pixel 8 cameras
In case you’re taking images, the sensor does not use the picture sensor’s twin conversion acquire expertise — at the very least but, although Google says it is excited in regards to the expertise’s potential.
However there are different huge enhancements: Like Samsung and Apple, Google is now advancing past the 12-megapixel smartphone photograph decision we have had for years.
When Apple launched its iPhone 14 Professional in 2022, it let photographers shoot 48-megapixel images with the primary digicam. Samsung goes even additional with a 200-megapixel sensor, although the outcomes aren’t usually spectacular past 50 megapixels. Compared, despite the fact that the Pixel 7 and seven Professional had 50-megapixel most important cameras, Google supplied images at solely 12-megapixel decision. (Although it did provide 2x and 10x modes that took benefit of the complete decision of its sensors.)
This yr, Google is leapfrogging Apple relating to pixel depend on the Pixel 8 Professional. Not solely can you are taking images on the most important digicam’s full 50-megapixel decision, you can even take 48-megapixel ultrawide (like this yr’s OnePlus 11) and 48-megapixel 5x telephoto photographs. (The Pixel 8 solely can take 12-megapixel ultrawide photographs.)

Like all flagship telephone makers, Google has employed a expertise referred to as pixel binning that provides photographers a selection between full-resolution photographs and decrease resolutions that work higher in low-light conditions. However this yr, it’s going to allow you to shoot full-res photographs even in low mild in the event you choose. That is not like Apple, which switches to pixel binning and low decision robotically when it is darkish.
“You’ll at all times get extra element by enabling 50 megapixels [than when shooting at 12 megapixels], even in very low mild, though you could undergo some noise penalty,” Reynolds stated.
You can even use Night time Sight for decrease noise. It really works at 50-megapixel decision.
Apple modified its most important digicam’s default photograph decision from 12 megapixels to 24 megapixels with the iPhone 15 fashions, launched final month. It additionally makes use of the HEIF picture format, which shops information extra compactly than the older JPEG. In case you’re a Pixel photographer, you may select the complete decision or 12 megapixels, however nothing intermediate. And there is no HEIF assist, as a result of Google prefers JPEG’s common compatibility.
We can’t know till testing whether or not Google’s high-resolution photographs are value it. Small pixels are worse relating to picture noise and dynamic vary. However Google has invested in higher {hardware}, together with wider aperture lenses that collect extra mild.
Pixel 8 digicam {hardware} upgrades
Each the Pixel 8 and Pixel 8 Professional get the brand new higher-end most important digicam with twin conversion acquire, and that gathers 21% extra mild than on the Pixel 7 technology.
Each telephones get a brand new selfie digicam, however it autofocuses solely on the Pixel 8 Professional. Higher picture processing doable with the G3 helps enhance colour and cut back noise on each telephones, Google stated.
And as with the 2022 telephones, solely the Professional mannequin will get a 5x telephoto digicam. It makes use of the identical sensor because the Pixel 7 Professional, however this yr, the Pixel 8 Professional will get a wider f2.8 aperture lens to assemble 56% extra mild. That is the identical aperture as on the iPhone 15 Professional Max’s 5x telephoto.
“We’re going laborious on low mild,” Reynolds stated. A secondary profit: Switching to the 5x digicam is quicker as a result of the telephone can lock focus extra swiftly than with the Pixel 7 Professional’s f3.5 lens.
Images and movies are a prime precedence and a aggressive sturdy swimsuit for for Google’s telephones. This closeup of the “obsidian” coloured Google Pixel 8 Professional exhibits its bigger new 48-megapixel ultrawide digicam at left, its up to date 50-megapixel most important digicam within the heart and its 48-megapixel 5x telephoto digicam at proper.

Solely the Professional will get an improved ultrawide digicam. It will probably collect 105% extra mild due to a bigger sensor with a wider-aperture lens. That is vital for low-light scenes and for supporting the 48-megapixel decision.
The Professional’s ultrawide digicam additionally will get autofocus skills and reduces its close-focus distance from final yr’s 3cm to 2cm — about 0.8 inch. Meaning macro photographs can have significantly better background blur, Reynolds stated.
New Google digicam app will get “professional controls”
Google is happy with its “computational uncooked” expertise, which mixes the multishot mixing used to create bizarre JPEGs with the modifying flexibility of uncooked images. Meaning extra dynamic vary than with single-frame uncooked photographs, which is useful for individuals who edit their images afterward in software program like Adobe Lightroom.
With the Pixel 8 telephones’ digicam app, Google is giving photographers new controls to present photographers fine-tune their photographs as they’re taken. It is bought new “professional controls” that expose choices for shutter pace, publicity size, white stability, ISO sensitivity and focus, Reynolds stated.
Most individuals will not shoot uncooked or use the handbook controls, however that does not imply it isn’t vital. “It will get you the photograph you want while you completely must have it a sure means,” Reynolds stated.
One other huge change to Google’s digicam app has already began arriving. For years, that app has introduced buttons with a selection of modes like photograph, video, panorama, Night time Sight and sluggish movement video. Now Google provides a grasp change for video and photograph, every with its personal vary of buttons.
Additionally new to the digicam app is an enchancment to the DNG information used for uncooked images. They now retailer extra metadata so software program like Adobe Lightroom will show a model that higher matches the colours and tones of the Pixel’s fine-tuned JPEG. Uncooked images generally have been retuned for higher colour and delicate tonal variations, Google stated.
The Pixel 8 telephones are the primary smartphones to make use of Extremely HDR, an Android photograph format that provides further data to a JPEG photograph so appropriate software program can present a excessive dynamic vary model. As an example, Extremely HDR brightens stars in astrophotography images, which present extra element at 50-megapixel decision.
New Pixel 8 taking pictures tips
The brand new Pixels include different skills, too, many utilizing synthetic intelligence expertise. Listed here are some:
For group images, a brand new characteristic referred to as Greatest Take allows you to select the faces you need from a bunch of images. It exhibits thumbnails of every face within the images, and while you faucet on one, it exhibits you the varied expressions. You’ll be able to decide all people’s finest smiles or goofy faces for the composite photograph the digicam creates.The G3’s AI acceleration skills robotically reduce noise from crowds and wind out of movies. However a brand new modifying software referred to as Audio Magic Eraser isolates completely different sounds to allow you to decide what you need. Sound stage sliders alter the combo of sound from speech, wind, music, crowd hubbub and background noise.A brand new Magic Editor software allows you to improve or lower the scale of scene components like folks. One faucet outlines a scene ingredient, then pinching or dragging strikes it round. Like Video Increase, this software goes to Google’s cloud computing system to do the heavy lifting of making any new imagery that is wanted. The software will solely be out there in an early entry model to start out.Google has taken some measures to enhance lens flare issues frequent on smartphones. Amongst different issues, when taking pictures towards vibrant level sources of sunshine just like the solar, the Pixel can take away the distracting inexperienced dot such sources usually produce.Magic Eraser, which helps you to obliterate scene components like distracting folks within the background, will get a giant AI increase. It now makes use of generative AI so the telephone can fill in bigger areas. It can also take away shadows from chosen components you are erasing.
How properly all these options and applied sciences work stays to be seen. However it’s clear Google is investing closely within the Pixel photograph and video expertise.
