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 ←

NVIDIA Slow Motion Interpolation With AI Deep Learning Tech!

NVIDIA Slow Motion Interpolation

NVIDIA has been hard at work on the problem posed by high frame rate interpolation of video data shot on lower fps.  We have had this tech since the late 1990s with the advent of Twixtor and refined over the decades in systems like Twixtor Pro and Adobe’s Optical Flow in After Effects. You are still not getting real temporal detail data since the frames are created by extrapolating velocity and direction vectors plus pixel values between frames to get the result.

We explored this technique in our post on interpolation here and why it is no substitute from a real slow motion camera solution.  NVIDIA’s new method uses machine learning along with 11,000 videos to arrive at a more convincing result. Considering the relatively small sample size we can imagine a future where hundreds of thousands or millions of footage samples are used to generate near flawless interpolation. This technique takes some serious computation and data sets so as of now it is not really ready for the mass market but that could change with the cloud very soon. → Continue Reading Full Post ←

Lenovo ZUK Z2 960fps Slow Motion Just Interpolation!

Lenovo Zuk Z2

The slow motion phone that was gathering a lot of interest regarding it’s capability was the Lenovo Zuk Z2 Pro with a spec reported to be 960fps.  Such a spec would leapfrog the current iPhone 6s and Google’s Nexus 6P 240fps 720p spec. However it seems such bold claims are usually met with a reality that does not match such claims.

The Youtube channel C4ETech “Subscribe Here” has had a go with the Zuk Z2 and found that the spec is pretty much smoke and mirrors. The 960fps spec which was supposed to be HD quality and full frames is nothing more than 120fps 720p interpolated by software up to 960fps. It doesn’t even allow real 240fps like other competitive phone options. → Continue Reading Full Post ←
