Camera Video Recording

Video recording on the Pixel 3’s is still limited to 720, 1080 and 4K at 30fps. The resulting video is encoded in H.264 and Google offers a switch to enable EIS, or to leave it disabled and solely rely on the OIS of the camera. The disadvantage of EIS of course is that it’ll result in a narrower field-of-view compared to the native FoV of the camera.

Pixel 3:      Pixel 2: 

Overall, the only big difference in video recording quality between the Pixel 3 and its predecessor, at least in these sample videos, is that the Pixel 3 is seemingly doing a much brighter exposure. This also resulted in some loss of contrast in some scenarios, and also less saturated colours. Oddly enough the new Pixel 3 also limits the digital zoom available when video recording, only going half as far as on the Pixel 2.

Speaker Evaluation

The Pixel 3 comes again with stereo front-facing speakers. This time around Google promises great improvements in the audio quality thanks to improvements in the software audio processing. To test this, we’re using our new speaker measurement methodology, and to do more direct comparisons I also revisited the Pixel 2’s speakers so that the size difference to the Pixel 2 XL doesn’t affect our evaluation.

Speaker Loudness

In terms of speaker loudness at maximum volume, the Pixel 3 is about 0.6dB louder when holding it in one hand, and showcases a 1.1dB advantage when cupping the phone with both hands. There’s some variability here as I prefer to measure the phones in-hand, as to represent the audio response as you would have when listening to the phones in real life.

The small difference between the one-handed and two-handed results showcase the front-firing nature of the speakers, showing that they have good frontal directionality.

Moving on, we’re doing a frequency response measurement sweep from 20Hz to 20KHz. The measurement is done with the phone in landscape mode held in two hands, with the palms again naturally cupped around the phone, as you would hold it when gaming.

The one very weird result about the Pixel 3 that differs from any other phone I’ve measured, is that the speakers go a lot further in the high frequency range than any other phone. Now this should be positive in general, however the Pixel 3 here oscillates significantly in terms of volume at the high frequencies, and this is plainly audible when doing the frequency sweep test, something unique to the Pixel 3.

Applying a psychoacoustic averaging filter to the results and comparing it to the Pixel 2, we see exactly how the speaker improved in terms of its sound output. I calibrate the volume of all phones in this comparison to a level of 75dbA on a pink noise output, so all phones are at the same perceived volume.

The Pixel 3 improves throughout from the bass range up to the low mid-range, showcasing a significant increase in volume in these frequencies, something that should be immediately audible. The Pixel 3 also has an abnormally loud output in the high frequencies above 15KHz – normally where other phone speakers would drastically fall off. The issue here is whether the big dip around 12KHz will adversely impact the phone’s audio.

It’s very hard to accurately convey speaker quality as recording equipment will always change the frequency response. I tried my best in terms of measuring this as best as I can through recording the phone’s output through a binaural microphone setup. The best playback experience for these recordings is achieved through headphones, or better, IEMs.

My calibrated speaker setup is meant to serve as a baseline to which the recording microphones should be compared to.

Comparing the Pixel 3 to the Pixel 2, there an evident increase in bass and depth of the audio, marking a significant improvement over last year’s model. The issue here is I feel there’s too much components in the high frequencies and the sound can seem notably harsh and shrill at maximum volume.

Another issue is that the phone is seemingly suffering from distortions – this something that I’ve also encountered on the G7 and seems to be linked to the fact that the glass back of the phone is allowed to vibrate a lot, instead of the sound pressure going out through the speaker grill. Also, if you happen to partially cover the bottom (bass) grill, the speaker membrane will notably distort. Pressing against the back will also change the frequency response of the audio.

Overall, the Pixel 3’s speaker are still a significantly improvement. I still prefer the iPhone XS and S9+ speakers – but the Pixel 3 is not far behind, especially having very strong mid-ranges.

    You're looking at this wrong, *flash*, not night sight, should be the last resort. On axis flash is almost always ugly and detrimental to what you're trying to capture, and severely interferes with post processing, night sight saves the need for flash, which is the way to go.

    "I’ve never really understood why people claimed the Pixel 2 camera to be good in low-light, because in my experience as well as visible in these sample shots, the Pixels were never really competitive and are outclassed by the better sensors from Samsung and Apple, when capturing in traditional modes."

    It's not that Samsung or Apple used 'better sensors', they just used longer exposure times (down to 1/4s), while the Pixel 2 would try to stick to 1/25 to 1/40s to avoid motion blur in human subjects, and only reluctantly dropping to 1/15s in very very dark situations.

    The reason many were impressed by the low light performance of the Pixel 2 was that it could retain good image quality in *less* low light (but still low light - such as indoors) conditions, while not having human subjects blurred. Also, iPhone motion estimation would jack up the shutter speed (to ~1/30s) when any movement was detected (human subject or shaky hands), and image quality would drop drastically, below that of the Pixel 2 (b/c it wouldn't also average as many frames as the Pixel cameras do). Things have improved with the XS.

    So it's a question of *how* low light of a scene are you interested in, and are you photographing human subjects or still scenes.

    Thanks for the review, very nice comparisons, and great work in particular with your display evaluation. It's irksome that despite having a proper CMS in the OS, every app appears to be rendering to sRGB. Google Photos app is even color profile aware, but converts images with ICC profiles (say: P3 or even ProPhotoRGB images) to sRGB for output (which means in 'Adaptive' screen mode, the sRGB output gets stretched, yielding oversaturated inaccurate colors). This just isn't how color management is meant to work - the CMS should take the embedded ICC profile and convert to the display profile.

    Love the detailed review, Andrei.
    Could you comment on the quality of the sound recording of the videos on Pixel 3, reading a lot of complaints on that.

    Andrei, thank you for the thorough review, especially the display section.

    Did you evaluate display uniformity at all? A lot of users (me included) are reporting a green-to-pink gradient across the display. It's very easy to notice with a gray background at low brightness levels in low to moderate light (think: using the phone in bed with only a bedside reading lamp illuminating the room). I'm curious whether only some devices are susceptible to this or if you noticed it on your Pixel 3 sample as well.

    Going forward, I would really like to see some measurement of uniformity included in display evaluations. If the dE at the centerpoint of the display is very low, that's great, but if the display isn't also uniform it can be a misleading indication of the overall quality of the display.

    Thanks!

    What's the best screen mode for pixel 3?
