edgertronic firing on all cylinders!

edgertronic

One of our favorite high speed camera companies has shared a lot of information regarding it’s COVID pandemic operations as well as unit shipments for their cameras. It looks like Sanstreak corp the parent of edgertronic is considered an essential business to the government which is probably because of the support and software development they do with clients for important government agencies. They have sold thousands of cameras to date and the company seems to be on firm footing to continue solidly into the future.

Their product line has the SC1, which is the 700fps 720p camera that started it all, as well as the SC2/SC2+ 720p at over 4000fps and SC2X over 2000fps at full HD 1080p. Check our page here for full in-depth reviews on these three cameras. Our favorite the SC2X is capable of a beautifully detailed and artifact-free image that can be used for cinema and broadcast. The SC2+ has the edge in frame rates with speed as a primary focus being able to record 6x the frame rate of the original edgertronic. The cameras have Color and Monochrome options if needed. → Continue Reading Full Post ←

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 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.

Fuji X-S10 Slow Motion 240fps Samples!

Now that the surprise camera of 2020 has been out for a while, it is time to revisit the 240fps mode included in the video features. At first glance, it delivered 720p quality or less in an upscaled 1080p wrapper.  However many Fuji fans asked us to revisit the slow motion quality of this camera as early samples supposedly did not do justice to what this mode was able to deliver.

We have to agree to some extent that the quality of this camera in 240fps Full HD slow motion is better than other even more expensive options but we still feel that Fuji cut corners when it comes to image quality here by dropping lines and having a pretty noisy output unless there is an ample amount of light.  We have some samples that will let you see what this camera is capable of and make you decide if it is a good enough option for your camera collection.

Fuji X-S10 Slow Motion 240fps Samples:

The camera can shoot up to 6 minutes in high frame rate mode and saves the file in a 60fps Full HD file for playback according to the official manual here. You can always lower the frame rate further to conform for 24p, 25p, and 30p if needed.

thCam Slow Motion Camera Kickstarter Campaign Canceled!

thCam Slow Motion Camera

(Note: As of November 23rd this campaign has been canceled due to lack of funding in time. )There is a new dedicated Slow Motion Camera being built by engineer enthusiasts and a Kickstarter campaign has just launched with the goal of gathering enough funds for production.  The camera is called thCam Slow Motion Camera and is capable of shooting above 3,000fps at reduced resolution with a 1920px horizontal. The 1080p frame rate maxes out at 266fps  and 576fps at 720p.

What is most impressive about this camera is the Machine Vision applications that can run with the platform like being able to train it to recognize QR codes, objects, and possibly even people. It could theoretically be used as a quality control camera that operates at very fast speeds. The other big deal is the price which is about $1,000 USD or €899 Euros which is a first for a camera of this kind.

thCam Slow Motion Camera Specs:

  •  Image sensor: 1920×1200, 10 bit Raw CMOS 2/3″ on 2MP Version
  •  Framerate: 240 fps (@ full resolution: 1920 x 1200), 576 fps (@ 1280 x 720), 1524 fps (@ 640 x 480), 3134 fps (@ 320 x 200)
  •  Pixel pitch: 4.8 µm
  •  Shutter: Global shutter
  •  Lens: included, compatible with every other C- / CS- Mount lens
  •  Image Sensor Size: 2/3” Optical Format
  •  Spectrum: Just visible light, no NIR (but the built-in NIR-cut filter can be removed or exchanged with another filter if you are willing to disassemble the thCam)
  •  Min. Exposure Time: 1 / 25,000 seconds
  •  Screen: multitouch capacitive lcd touchscreen
  •  Memory: 8 GiB (record time 12s)
  •  Battery: replaceable and rechargable li ion battery (continous recording time: > 2 hrs, stand-by mode: > 6 hrs)
  •  USB: USB 3.0 SuperSpeed connectivity
  •  Synchronization: External Monitorsignal and Trigger/Sync Port
  •  Software: Open Source, running on Windows (7 and above) / macOS (10.15 and above) / Linux
  •  Supported File Formats: Image Sequence (Raw, Jpg, Png), Video File (Mp4 / H.264)
  •  API: Open Source, use the camera in your own code (C++, Python, Java)
  •  Case: Aluminium case
  •  Dimensions: W x H x D = 14 cm x 8 cm x 5 cm (estimated values)

As you can see, the camera is no slouch, it can record up to 12 seconds of RAW video and can be used and controlled remotely with programming commands if needed. It uses a C mount much like other cameras in its class and has a 2 hr battery life while recording and up to 6hrs standby.  The batteries are a couple of 18650s which are common and widely available.

There are also options to only get the PCB boards with a sensor instead of a fully built camera at a lower price of €649 for the 2MP sensor version.  Some engineers are more inclined to adapt the PCB to their own pipeline instead of using a self-contained camera unit.

The Kickstarter Campaign:

The campaign here: https://www.kickstarter.com/projects/thdevices/thcam-3000-fps-slowmotion-camera

The creators of the camera a Swiss and German engineer team are asking for a pledge goal of $94,779 USD or about €80k Euros.  For under $1000USD depending on the exchange rate, this is a cheap slow motion camera that has a lot of potential with RAW image quality that seems above good just looking at the provided samples.

Footage is recorded as 10 Bit RAW Image Sequences, full control of white balance, color tone, contrast, and brightness no compression. After editing you may compress your video to standard formats (H.264).

The camera features a Global Shutter so no rolling shutter artifacts to spoil your experiments.

The thCam comes with an equipped 8 GB memory module, enough to record about 12 seconds in full resolution with maximum framerate. Standard SODimm 204 DDR3 Computer memory modules are used, so you are free to upgrade your camera later on.

The camera also comes with a Super Speed USB 3.0 port. This high transfer rate allows you to stream images from the camera in realtime and low latency.

The camera also has an Open Source SDK that allows for programmability and full remote control of the camera via USB 3.

Supported Languages will be Java, Python and C/C++.

Our Take on the thCAM:

This is a pretty neat little camera with a lot of potential for labs, engineers, education, sports, and imaging enthusiasts/hobbyists.

It has a great interface with easy controls that is working and ready to go. It has extensibility via software and can be controlled remotely by USB 3.0 with instant feedback.

The video samples do show some noise, chromatic aberration, and softness but looking at some of the other demos, it is clear these are mainly due to either low light or a pretty bad quality lens used. If you coupled this image sensor with better high-quality glass like we have seen in other C mount cameras, it is easily going to produce beautiful imagery.

For $1,000 USD for a fully assembled and working camera, we do not believe there is a deal out there that can compare. Sure you only get a maximum of 266fps in 1080p but we do get 576fps at 720p which is better than what many prosumer cameras can shoot at and the fact that we have RAW here makes it that much sweeter.

For production houses and serious videographers, it is clear this camera will not fit the bill as the smallish 2/3rds sensor could pose problems with image quality for broadcast and film unless the conditions were ideal with ample light control. This camera is not intended for that market in our view. This camera is intended for serious scientific experimentation and motion analysis with the possibility to extend its capabilities with software.

As a sports training device, it could be the best-priced camera of it’s kind with enough quality to analyze body motion on the fly and on location with its portability and 2hr recording and 6hr standby battery. We can see golfers and gymnasts gravitating to a solution like this especially with the flexibility and price.

The team of the Ackermanns is entering the space with the thCam but hopefully, we will see a more image quality-oriented camera as a future product with a higher price but not extremely above this first iteration. If they could produce a similar 1080p camera at 1000fps or 2000fps we are sure it would make a gigantic splash.

We wish the team luck on their campaign which looks to be ready for production, hopefully, we will continue to see impressive engineering from this team for years to come. -HSC
