Alice Camera and why the Future is Bright!

Alice Camera

The Alice Camera, launched to great success this month has to be the most hopeful product for the future of cameras that we have seen lately. It marries the Sony IMX294, a 10.7 megapixel 4/3 sensor with a custom chipset including the Edge TPU chip from Google for AI and an FPGA for calculations.  The result is a camera body with the same sensor as the GH5s which is a killer low light camera capable of excellent 4k footage and images with super low noise.

Then the camera back is attached to your Android or Apple smartphone to gain an interface and software to control it. The camera is capable of using the latest research for computational photography including HDR with multiple exposures merging, tracking, night mode, averaging of pixels, and as an open-source architecture, you can add features by other coders or your own to make the camera increase the feature set. → Continue Reading Full Post ←

Sony a7s III Slow Motion Samples!

Sony a7s III Slow Motion Samples

Now that the excellent a7s Mark III video recording mirrorless camera has been out for over six months, it is time to revisit the slow motion component and see what quality we can expect from the Sony a7s III Slow Motion Samples. Many have praised the 4k 120fps mode which is heavily detailed, low noise and suffers from only a very small crop factor that is hardly a problem.

We looked at the Full HD 1080p 240fps mode on the camera and it was clear it did not match the 120fps 4k mode as it was not only less detailed but full of aliasing and moire if you looked for it. It was clear the camera was not up to professional standards when in this mode which is to be expected from a full-frame sensor cropping to 1080p. That said, this camera is a powerhouse that easily takes the mantle as Sony’s best mirrorless compact video camera.

Sony a7s III Slow Motion Samples:

Be aware that 120fps in 4k is not only highly detailed and full of dynamic range but it is the best high frame rate this camera has to offer. You can easily use this mode for professional broadcast or film work is shot in good conditions.  The a7s Mark III is the best Sony Alpha line camera for low light performance and it is evident by the samples this translates directly into higher frame rates.

Fujifilm X-E4 Slow Motion 240fps disappoints!

Fujifilm X-E4 Slow Motion

The recently released camera called the Fujifilm X-E4 shares many of the traits of their lower brethren but also from the higher-end models in a compact package. It ditches the better viewfinder for a small 2.36 million dot EVF that makes it a bit hard to see your composition but that also allows the camera to be smaller and more stylish than the beefy SLR style Fujis out there.

The Fujifilm X-E4 Slow Motion feature is the same as found on cameras like the excellent Fujifilm XS-10 which is a 120fps or 240fps full HD component that records in camera. Why are we not excited? well, the quality is lower than expected with some aliasing and moire characteristics that are so last decade. When are manufacturers going to offer the same 1080p quality at all frame rates instead of relegating the 120fps and 240fps modes to the lower bitrate and detail bin?

Fujifilm X-E4 Main Specs:

  • 26.1MP APS-C X-Trans BSI CMOS 4 Sensor
  • DCI/UHD 4K at 24p, 25p & 30 fps
  • 2.36m-Dot 0.62x OLED EVF
  • X-Processor 4 Image Processor
  • Compact classic body
  • 3.0″ 1.62m-Dot 180° Tilting Touchscreen
  • 425-Point Hybrid AF System
  • Film Simulation Modes
  • Bluetooth and Wi-Fi Connectivity
  • Lens Kit includes: XF 27mm f/2.8 R WR Lens
  • MSRP: 1,049.00 USD Lens Kit or $849.95 Body only!
  • Release date March 11th, 2021

Fujifilm X-E4 Slow Motion Specs:

Full HD (1920 x 1080)

  • 50p/59.94p
  • 100p/119.88p
  • 200p/239.76p
  • [100 to 200 Mb/s]

While we get the same frame rates as the best value/performance on Fuji’s arsenal the XS-10, you get the aliased version of the footage. While the final quality is passable for your Youtube Vlog, it will not be ready for more professional uses, the pixelation and stair-stepping looks like badly captured 720p video in a 1080p wrapper.

The video below by the amusing and great Kai W, has a sample of 200p video on the camera at the 4-minute mark.  You can clearly see the aliasing in the footage when you load it at full resolution.  We expect the 120fps mode to be much better but we already get pretty good 120p footage from most cameras nowadays. The 240fps mode is the standout here and it disappointed us fully.

But what about?

Can you still make a remarkable slow motion shot with this camera?  In a word, Yes take a look at the Fujifilm’s XS-10 240fps mode which is probably the same as the one in the X-E4 as they share a lot in common feature-wise. Look closely at the very well shot video below:

Sony A1 Slow Motion has 8x Mode!

Sony A1 Slow Motion

Just in time for the Japanese Olympics if they ever take place, Sony has released the Sony Alpha 1 or A1 for short which is probably the most powerful mirrorless camera ever produced.  Customary for Japanese camera manufacturers in Olimpic years, the likes of Canon and Nikon have released their professional flagship products like the  1DX and D6 which are still SLR mirrored products that have the highest possible Autofocus features for a camera of that type as well as speed and dependability.

Sony has had some inroads in that space with the Sony a9 series but they were missing a higher megapixel count version that could really differentiate it from the pack and the A1 seems to be just that kind of product. By shooting 8k video at 24,25 and 30p it becomes future-proof for the next decade as far as resolution goes and by taking 30 images per second in stills mode at the full 50MP resolution with AF Tracking, it is one blinding fast beast.  The fact that it also shoots 120fps 4k and 240fps Full HD doesn’t hurt it either.

The Sony A1 is probably the fastest mass production professional hybrid camera ever made. The speed required for 50 megapixels at 30fps means that it is processing and saving in RAW format or RAW+JPG to CF Express Cards  at 1.5 Billion Pixels/Second and all of this while using the 120Hz continuous intelligent Auto Focus for people and animals.

The Slow motion frame rates are also here with up to 4x 120fps in 4k 10 bit at up to 280Mbits/sec and 100 to 240fps 8x in Full HD 1080p at 50Mbps.   We can see the sample below that contains several clips at 4k 120fps and some intercut 240fps Full HD like the divers shot in Hunters Of Light below.  We can safely say that the quality at 4k 120fps 10 bit is near perfect but we still cannot attest to the quality of a file in Full HD at 100, 120, 200 and 240fps derived from a Full Frame sensor recording from a 50MP source.

We have confirmed that the camera has a 21 Megapixel crop factor in APS-C size for stills and possibly video which probably means that all the higher 1080p frame rates are possibly extracted from the crop area of the sensor and not from the full 50MP area.

Galaxy S21 Slow Motion Feature is Retained!

Galaxy S21 Slow Motion

This week we had the announcement by Samsung of the Galaxy S21 phone line which is the de-facto Android handset in most of the world.  The Galaxy S21 Slow Motion has essentially the same feature set as the Galaxy S20 of 2020 when it comes to high-speed video. The Galaxy brand went serious with Slow Motion since the Galaxy S9 with the 960fps mode at 720p which we can still see here with somewhat improved resolution and recording time.

The S21 line is by almost any standard a refinement of the line with very subtle but important updates on the previous S20 phones. We get the Snapdragon 888 which is the brightest and fastest SoC in non-Apple land. We get 120Hz adaptive screen refresh rate and 108MP telephoto camera on the Ultra version with 10x hybrid zoom, and half that at 64MP on the regular S21 and S21+ which only offer 3x hybrid zoom. We also get 8k video recording on all of the phones at 24p which we will have to test if it is really delivering on the promise.

Galaxy S21 Slow Motion Video Features:

Resolution

  • 8K video recording at 24 fps (7680×4320)
  • 4K UHD video recording at 60 fps (3840×2160)
  • 1080p FHD video recording at 60 fps (1920×1080)
  • 720p HD video recording at 30 fps (1280×720)

Shooting speed

  • Super Steady 1080p video support at 60 fps
  • Super Slow-mo 720p video support at 960 fps
  • Slow motion 1080p video support at 240 fps & 120fps
  • Hyperlapse 4K video support at 30 fps

Other

  • HDR10+ recording
  • VDIS (Video Digital Image Stabilization)
  • Digital zoom up to 12x
  • High CRI LED Flash
  • Tracking AF
  • Take 33MP still photos while playing 8K video
  • Playback zoom
  • Video location tags
  • *HDR10+ recording is currently in beta and only available on the rear camera. Quality may vary based on sharing platform and playback environment; HDR10+ color is only available on supported devices or platforms.
  • *Super Steady is only available when shooting in FHD resolution.
  • *Super Smooth 60fps Video supports FHD resolution in Auto mode only.
  • *Super Slow-mo only supports HD resolution. On Galaxy S21 5G and S21+ 5G, users can record approximately 0.5 seconds of video captured at 960 fps with approximately 16 seconds of playback. On Galaxy S21 Ultra 5G, users can record approximately 1 second of video captured at 480 fps and digitally enhance the video to 960 fps with approximately 32 seconds of playback. Playback time can be edited in Super Slow-mo player.

Samsung Galaxy S21 event in 12 minutes by The Verge:

Same feature, mildly upgraded results!

So we get 960fps recording in 720p only in the S21 and S21+ phones and not in the Ultra. The Ultra version is capped at 480fps 720p and then AI deep learning interpolates to 960fps slow motion for the final result on the highest spec phone.

It is the same as last year’s S20 which also featured that limitation on the Ultra version of the handset.  It is not a matter of processing power but it is based on the choice of sensors. The Ultra seems to be capped at 480fps while the non-Ultra can scan at 960fps in 720p.

When it comes to slow motion the cheaper phones are actually more capable which may be ideal if this feature is important to you.

On the S21 and S21+ you get 0.5 seconds of 1/2 a second recording time at 960fps which translates to 16 seconds playback at 30p.  On The Ultra you get 480fps for 1 second recording time and interpolated to 960p for a 32 second playback time at 30p.  This is exactly the same as last year’s S20 line.

We have to test the feature fully but we estimate slightly better color, dynamic range, and artifact control on the S21 but nothing that would make you upgrade your S20.

Galaxy S21 Slow Motion Early Samples:

We will be testing the Galaxy S21 in the coming weeks as we are receiving a test unit. In the meantime, we found some samples online that could be legitimate. They certainly look real in resolution and speed for the most part but it is so early that we cannot confirm their validity.  We will re-examine the slow motion samples in a later post at HSC including our own tests.

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:
