Best Slow Motion Phones of 2019!

Best Slow Motion Phones of 2019

This year we have decided to have a special post to highlight the advancements in smartphone camera systems that allow the recording of super slow motion video. We have seen after all huge advancement this year especially by Asian companies making their best efforts to exploit the camera module’s strengths without crippling them to sell a newer model. The Chinese have decided to create a camera war between phone builders that one-up each other every few months.

We value image quality just as high as frame rate and when phones claim to be 1080p in high frame rate modes we usually find that the real case if 720p or similar upscaled to full HD 1080 with artifacts and jagged edges that can make you dizzy. But not all phones are created equal and that is where this list of the best of 2019 comes in. If by any chance an even stronger contender comes in before the end of the year we might revise this list but it would be a fluke. → Continue Reading Full Post ←

Huawei Mate 30 Pro New Slow Motion Samples!

Huawei Mate 30 Pro New Slow Motion Samples

The Huawei Mate 30 Pro has been out for a few weeks outside the US, mainly in China and India and we have gathered 15 video samples from its slow motion mode which as of today is the best performing high-speed phone ever developed.  We had some shortcomings about the way the phone reaches the highly hyped 7,680fps mode which is 1920fps multiplied by 4x in software from a small snapshot of the video memory.

We also had some suspicions that the 1080p 960fps mode was also interpolated but looking at the samples we gathered it seems that was a premature call. The phone is actually capturing the full frame rate at 1080p or close to that.  The real max mode is 1920fps at 720p which is then interpolated to 7,680fps with good success by the new Kirin 990 chipset. Your mileage may vary and the results depend on the subject matter more than anything as organic slower motion looks much better than fast unpredictable bursts that break the interpolation algorithm. → Continue Reading Full Post ←

Huawei Mate 30 Pro Slow Motion The Real Story!

Huawei Mate 30 Pro Slow Motion

Huawei has just launched the Mate 30 Pro and Mate 30 Pro 5G Smartphones which sport an impressive camera module with a large sensor array that shoots at 40 Megapixels.  We had rumors sent a couple of weeks back but had our reservations due to the less than optimal slow motion in the P20 and other Huawei Smartphones.  The phone is now untouched by the competition as it can shoot a half-second at 1920fps 720p or 960fps total which translates to 32 seconds on a 30p timeline.

The headline slow motion feature of 7680fps is not real as it is derived from the 1920fps 720p half-second which the phone then uses AI selection to isolate a 0.12 seconds segment of the capture then finally interpolated by the Kirin 990 Chipset to the full 7680fps. So it does a 4x slow motion on top of it to get the great-looking result. → Continue Reading Full Post ←

Galaxy S10 Slow Motion Video Samples!

Galaxy S10 Slow Motion Video Samples

Now that the Galaxy S10 has been shipping to customers for a couple of weeks we can now see a plethora of video samples showing the 240fps 1080p, 960fps 720p and 4k 60p high frame rate modes. We can clearly see a better compression on the new S10 samples compared to the Galaxy S9 in all modes. There is still some aliasing and moire but it is very well controlled.

Noise doesn’t become a problem unless it is very dark which means the Samsung noise reduction is doing an incredible job.  It is maybe too clean as some detail seems to be flattened out to control for artifacts. All the Galaxy S10 variants shoot the same quality slow motion in the main camera module so if you want to only get the S10e for it’s lower price of $749 you get to keep the high-speed feature intact. → Continue Reading Full Post ←

Galaxy S10 Slow Motion Recording Is Slightly Improved!

Galaxy S10 Slow Motion Recording

So it seems the rumors were true about the slow motion component being preserved on the Galaxy S10 phones from last year’s S9. Last year the stand out feature of the phone in video mode was the slow motion capability and it was one of the main selling points for the Galaxy S9.  We got no mention of the feature during the Samsung event today for the S10 but we can find it buried in the phone specs with some details.

It seems the feature is slightly improved in bit-rate quality, color, and dynamic range. However, the main improvement is the recording time which has gone up to 0.4sec from 0.2sec and up to 0.8sec in 480fps mode which is half the frame rate.  In essence, it seems the phone is now the flagship slow motion performer for Samsung. → Continue Reading Full Post ←

Xiaomi Mi Mix 3 960fps Mode Uses Interpolation?

Xiaomi Mi Mix 3 960fps

The Xiaomi Mi Mix 3 had a few leaks in the past weeks concerning the slow motion mode and the company even released a water balloon sample. We decided to wait for the real reviews and samples before making an opinion on this phone which is destined for the Chinese market first. The phone is supposed to shoot 960fps in 1080p mode which is exciting as an initial spec matching the Sony Xperia XZ2 and XZ3 phones in resolution and frame rate but we really have no slow motion duration spec yet.

After looking at the samples we have seen a clear indication of software interpolation to fill in video frames between high frame rate recorded video which looks to be 240p at 1080p and then conformed in software to 960fps on the fly using the phone’s hardware. The results are very good and beat anything we have seen before on phone frame rate interpolation which is a good thing, however, it looks like the phone is faking its way into slow motion 960fps. → Continue Reading Full Post ←
