Samsung ISOCELL GN2 does 480fps!

The hegemony of phone sensors has been the purview of Sony with their Exmor sensors for many years but now Samsung has started making inroads in the space with their ISOCELL chips. The latest is currently mass-produced and shipping in handsets already which is not a paper launch, but a real thing. The chip is capable of massive low light improvement compared to other sensors because it is essentially a near 1″ sensor with 1/1.12-inch measurements. This is close to what Sony RX cameras use as a main sensor, and a first for a phone.

As to how they are able to fit this sensor on phones, it is a dance between a protruding camera bump that is a little larger than usual and also a lens system that creates a full imaging circle from a minute distance. The GN2 is capable of recording 480fps in HD 720p, 4k 120fps, 30fps in 12.5MP windowed size and 10fps in 100MP mode which uses a clever algorithm and three RGB exposures to derive a 100MP image from the 50MP source. → Continue Reading Full Post ←

Xiaomi Mi 11 Ultra Slow Motion Mode 1920fps Fake?

Xiaomi has surprised this year with now the Mi 11 Ultra phone which is a big step up from the Mi 11 released earlier this year. The huge difference lies in the size of the sensor which is close to a 1″ camera sensor like those found on the Sony RX camera series for example. The phone has two 48MP sensors and a main 50MP sensor for the main camera with a highly protruding camera bump that really screams for a case to be able to balance well on a flat surface.

The slow motion modes on the phone are rumored to be the garden variety with 120fps/240fps 1080p, 60fps 4k, and also a selfie camera that does 720p 120fps which is becoming commonplace. What is really peaking our interest is the 1920fps slow motion mode that is touted by some reviews. It is unclear what the phone is capable time-wise as the specs are still not all there. The samples we have seen show detail loss and the clear signs of interpolation. → Continue Reading Full Post ←

Xiaomi Mi 11 Slow Motion has a 480fps mode!

Xiaomi Mi 11 Slow Motion

There are many new phones about to be announced including the most awaited Samsung release of the year, the Galaxy S21 which is due in a day or so. However the Xiaomi Mi 11 which was recently announced has been making a great impression on reviewers with a fluid 120Hz display, above-average camera features, 8k video, and our main interest the slow motion recording modes.

The high speed mode includes a 240fps 1080p mode but most interestingly this extends to 1080p 480fps which might be of comparable quality.  The Xiaomi brand has been making cameras and phones for a few years now and while it is usually discounted as a budget brand, the inclusion of pro features like a Snapdragon 888 processor and a whopping 108MP main camera make it stand apart.

Xiaomi Mi 11 Slow Motion Modes:

Main Camera:

  • 4k video at 30p/24p/60p
  • 1080p Full HD: 30/60/120/240/480fps
  • 8K video recording: 24/30fps

Selfie Camera:

MAIN CAMERA Triple 108 MP, f/1.9, 26mm (wide), 1/1.33″, 0.8µm, PDAF, OIS
13 MP, f/2.4, 123˚ (ultrawide), 1/3.06″, 1.12µm
5 MP, f/2.4, (macro), 1/5.0″, 1.12µm
SELFIE CAMERA Single 20 MP, 27mm (wide), 1/3.4″, 0.8µm
Features HDR, panorama
Video [email protected], [email protected]
PLATFORM OS Android 11, MIUI 12.5
Chipset Qualcomm SM8350 Snapdragon 888 (5 nm)
CPU Octa-core (1×2.84 GHz Kryo 680 & 3×2.42 GHz Kryo 680 & 4×1.80 GHz Kryo 680
GPU Adreno 660

MSRP Price: $739.74

We are happy to see such a plethora of frame rate and a very high-end performance package all for under $1000USD, in fact, it has an under $750 price tag which is very tempting.

We are also happy to see 120Hz becoming commonplace as a default refresh technology for displays on most mid to high end phones. This makes the experience fluid and for slow motion video it allows you to see 120fps live if needed before getting to a video editor.

Xiaomi Mi 11 Slow Motion Samples:

We found what we assume are legitimate samples of the slow motion mode. The quality is not class-leading but not that awful either. You be the judge:

Slow Motion Phones and the Youtube Fakes!

Slow Motion Phones

Believable slow motion video samples on Youtube for phones and cameras are so confusing nowadays that you simply cannot rely on them unless it comes from a reputable source.  The avalanche of fakes is so big that it makes it next to impossible to find the real ones out there.  It also makes it extremely hard to choose a slow motion capable phone when the supposed videos you are looking at are faked from other devices or even professional slow motion cameras.

There is also the big problem of stealing real quality slow motion footage from other channels and using it in compilations that claim to be from a phone or camera in order to get clicks and views for quick revenue.  The problem goes even deeper when these fakes overtake most other real videos due to the viral nature of their compilations as they usually look much better than anything these cheap devices they claim to represent can do.   We examine a few cases that can educate you on how to spot these fakes!

Slow Motion Phones Sample fakes:

The Xiaomi Mi 10 pro, for example, is a phone that boasts the following specs in frame rates:

960fps 720P/1080P
240fps 720P/1080P
120fps 720P/1080P

Xiaomi is not very forthcoming with the specs of the slow motion as it does not specify duration or method of capture. The samples below show us the problem of fakes head-on:

Slow Motion News August 2019

Slow Motion News

We have a few developments to share in the high speed camera world. Things have been somewhat quiet in the phone front as the high speed component feature was relegated to a footnote in 2019 after a great 2017 and 2018 main spec treatment. We may get much better phone slow motion as memory size and speed increases while maintaining the same price range thanks to the fast pace of electronics development.

Sony just announced their latest RX VII camera which means that an RX10 and maybe a new RX VA version will show up before the year is over.  We were not happy with the feature being stagnant in resolution and speed on the RX series for 3 years in a row now. Sure AF and overall speed have increased when it comes to other parts of the camera but the high frame rates remain frozen in 2016 specs.  In the meantime, we have a few new things to show you.

Chronos 1.4c Camera Software V0.3.2 Development improves Frame Rates and adds new features:

We installed the Chronos V0.3.2 RC1 Beta software and on initial testing find the software to be mostly stable and the new features make it a better camera all-around.

In our testing, we found that noise and column gain was reduced considerably after a 15min warm-up.  Also, the saving to SDHC cards is faster in RAW mode, we were getting 4.8fps instead of 3.7fps in 0.3.1 this makes a very noticeable difference in saving speed which seemed too restrictive in RAW.

We did encounter some problems when using HDMI external monitors and viewfinders when using the peaking function. These are already being patched for the next release so we recommend you wait for v0.3.2 RC2 if that feature is needed while monitoring.

The camera now has the ability to format and see how much space is left on SD and USB/SATA media which is a very welcome feature set for on the field users. We would love the ability to load saved clips for playback at a later date as software evolves including post save editing and clip erase if possible.

Another welcome feature is now the ability to shoot even faster frame rates for all resolutions. 720p has gained 17 frames from 1502fps to 1519fps which is our main use resolution.  However, the camera is now able to shoot up to 40,420fps at 320*96 pixels which used to be 38,565 fps for a 1,855fps gain with no quality degradation. It is not often that you get free speed in any camera, this time it is lossless and operates just as before.

For more information on the Chronos 1.4 camera visit the Krontech.ca and or info on the patch at the development forum thread here: http://forum.krontech.ca/index.php?topic=488.0

Notable Changes:
– Automatic ADC calibration during black calibration, which should reduce column banding across a wider temperature range.
– Add a storage tab to the util menu to view, eject and format the attached storage devices.
– Speed boost at most resolutions, with a top speed of 1069fps at 1280×1024, and 40420fps at 320×96.
– Configurable automated power-on and off depending on the AC adaptor status.
– Option to disable the ring buffer when in segmented recording mode.

Minutae:
– Factory black calibration is now user accessible from the Factory tab of the util window.
– The software update button has been moved to the storage tab of the util window.
– Shipping mode to disable power-on by battery until an AC adaptor is attached.
– Add a watchdog to reboot the camera in case of a power-on boot failure.
– Display descriptive error strings instead of number on failure.

Fixed Bugs:
– Gated burst record mode may lock up after several trigger edges.
– Gated burst record mode unreliable when trigger debounce is enabled
– Memory leak in the M3 video coprocessors which could lead to a crash after lots of H.264 encoding.
– Ignore video which was recorded during zero-time black calibration (which happens after changing resolution).
– Stuttering issue on the playback window on new production LCD modules.
– Fixed deadlock in camera when restoring user settings from external media.

Fixed since V0.3.2-beta-6:
– Changes to focus aid or exposure aid (zebra stripes) would have no effect until resolution is changed.
– Changes to exposure may be overwritten during black calibration.
– Bad image quality at 336×120 resolution
– Util window, storage tab – bottom of text cut off if device has multiple partitions
– Factory black cal (black cal all resolutions) would get overridden by old user black cal, if a user had done their own black cal, even before.

Known Issues:
– On the save file settings window, the bitrate as listed above the resolution may be lower than the actual bitrate, if Saved File Framerate is lower than 60fps

Updating Your Camera
====================
– Extract the `.zip` file into the root directory of a FAT32 formatted USB drive.
– Turn on your camera and insert the USB drive into the USB/eSATA combo port, not the one labeled ‘OTG’.
– From the main window, tap the `Util` button to open the utility window.
– As a precaution, tap the `Backup Calibration Data` button on the utility window before starting the update.
– When the backup is completed, a pop-up window will be displayed.
– Tap the `Done` button to close the pop-up window.
– From the utility window, tap the `Apply Software Update` button to begin the software update.
– A warning message will be displayed, tap the `Yes` button to confirm and begin the update.
– If a pop-up that says ‘No software update found’ is displayed, even when a USB stick containing the update in the correct location is connected, reboot the camera and try again.
– During the update, the screen will go blank and an `Applying Update` message will be displayed.
– After approximately 60 seconds, the update will be complete and the camera will restart.

Xiaomi Black Shark 2 Pro Phone Announced with 1920fps at 720p!

As we have seen from Chinese phones this year, the 1920fps spec for slow motion at 720p is included in several spec sheets like the Nubia Red Magic 3 but we found out that it is not only a fake spec but the actual video quality is pretty low.  The phone uses a 480fps capture at 720p and then creates interpolation of 4x  which is 480 x 4 =1920fps to create the final video. In some phones, it is just playing back 4x slower but in others there is interpolation. WHatever the came may-be, you are better off by avoiding this feature in your buying decision.  The quality is low and compression high, then the stuttering of faking the 1920fps kicks in and you end up with a subpar experience.

Here is a video sample of what appears to be a real clip from the Blackshark 2 Pro. You can easily notice the interpolation.

Now for some fun, The Slow Mo Guys have played with a huge amount of Gallium metal which becomes liquid at under 30 degrees C and looks pretty close to mercury without the toxicity. They do remind us that Gallium corrodes Aluminum on contact as it amalgamates with it, Aluminum which is what most cameras and lens cases are made of are pretty vulnerable,  so if you try this with your slow motion camera, be sure to use a barrier. -HSC

Pocophone F1 will get 960fps Slow Motion Mode!

Pocophone F1 Slow Motion

The Pocophone F1 by Xiaomi is an ultra-budget phone about $289 USD on some places for the 64GB model which feels anything but cheap. It has a 4000mAh battery, 6GB of RAM, dual cameras and a Notch screen all powered by a Snapdragon 845.  Now the software updates will include a 960fps mode in 1080p for a very short rec time. Some initial tests put it at 25MB in size which might be about 0.2sec.

So you get a phone that also will shoot the 4k 60fps spec with the update but what about the video quality?  Actually, it is not that bad and quite competitive with some mid-range phones.  It will not be flagship quality like those $800 USD + phones but it will get the job done. When it comes to slow motion 120 and 240fps 1080p mode it does lower quality quite a bit which may be a preview of the quality that the 960fps mode will deliver.

Pocophone F1 Software update in February:

The =&0=& beta update was being pushed to testers in early December and the full update should be released in February with a focus on improving video features.

  • -960fps Slow Motion mode
  • -120 and 240fps Slow Motion
  • -4k 60fps video mode UHD
  • -Interface improvements
  • -Usability improvements
  • -Super Low Light Mode for Photo- 8 image stack for low light improvement!

The update should be pushed to Pocophone F1 owners by mid-February and be a seamless update.
