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 ←

Cheapest slow motion camera for $6 does 660fps!

Cheapest slow motion camera

We just received a video link for a Raspberry Pi imaging platform that allows for 660fps slow motion video capture using the computing unit along with it’s memory and a $6 USD camera to record slow motion video with better than expected results. The video from 2019 by RobertElderSoftware explains the way the camera and R-Pi were able to capture the footage using some scripting and writing a windowed wide but not tall imaging rectangle directly to memory to create the cheapest slow motion camera.

Of note is the apparent low resolution of less than VGA at 640 x 64px and the somewhat appraisal of rolling shutter artifacts on some of the coins. However, RobertElderSoftware also has a step by step instruction video set on how to get a $40 Raspberry Pi computer and a  $6 USD camera module to build your own homebrew slow motion camera with some scripting.  After a lot of scripting and patience, you should be able to mimic his results.

Cheapest slow motion camera using a Pi Unit:

It is literally amazing what a dedicated engineer with an extremely limited set of tools and cameras is able to do on a project like this. Now imagine RobertElderSoftware using something like a more powerful ARM-based Mac M1 or similar with way more RAM disk for capture along with a better camera and sensor combination.

You can visit and subscribe to Robert Elder’s Channel here and learn many more from his cool projects and coding guides!

Maybe in the future, we could see some homebrew project kit that could be able to shoot 500fps or even 1000fps in 4k for a limited investment. In any case, we feel that you should take a look at the project below and get inspired.  We thank our reader Nacho Simon for the heads up on this awesome project and Mr. Elder for his creativity and drive! -HSC

Multiply Your Video Frame Rate with Dain-App !

Multiply Your Video Frame Rate

We got over 20 messages with essentially the same video sample in our inbox this week. They all touted the new interpolation from the DAIN experimental App or (Depth Aware Video Interpolation App)  which now analyses footage with a Neural network AI algorithm that crunches motion vectors and even what seemed impossible before “Object Occlusion” to generate higher frame rates from lower fps sources.  The technology is pretty fascinating and should be further improved by more training and samples over the coming years.

For stop motion animators, this is a complete game-changer as now you could animate with as little as 8fps and then interpolate to 30fps or 60fps with very little in the way of tearing and artifacting as long as the footage is well lit and objects clearly defined.  To make matters more interesting, it also analyses footage with shallow depth of field yielding impressive results.

Multiply Your Video Frame Rate with Interpolation or the “I” Word for Slow Motion Enthusiasts:

We visited the Interpolation topic in the past on our Fake Slow Motion article and concluded that then, the quality of interpolation while good was far from usable and you really could not compromise real high fps footage from interpolated versions except in very simple cases.

Now with DAIN technology, we have no choice but to re-visit the cases and analyze what it is capable of.  We looked at a few dozen examples and it is clear the technology has progressed forward so much that now stop motion animation, 2D Cell-based cartoon animation, and even 3D animated sequences rendered at 30p can easily be turned in higher fps increments yielding impressive and in some cases miraculous results.

We would like you to first watch the video below to understand what a depth map is and how the software in DAIN can create frames from nothing that look just like real ones.  A depth map will generate an approximated view of the world in a Lidar-Like vision representation to figure out to the best of the AI estimation where objects are in a scene according to their location close or far to the camera.

Depth-Aware Video Frame Interpolation by Wenbo Bao:

Even at 48fps from  12fps source, it is clear the technology in DAIN can yield impressive results even with heavy organic detail in the background including foliage. The software does an admirable job of estimating the relative position of objects in the video scenes.

Lumix Camera as a Webcam using USB for free!

Lumix Camera as a Webcam

Panasonic has released a Beta tethering software package for use in Windows 10 that allows you to control your Lumix camera from the computer to shoot images and video while at the same time use it to monitor the live view video signal with now the specific change that lets you remove the overlay display items from the camera to get a clean feed to your video conferencing software.

However, it is not that easy to get it to work and requires a couple of free pieces of software to let you extract the live view feed from the camera and redirect it to a video conferencing application of your choice.  We were able to get it to work well and it really makes a difference compared to the small sensor webcams you have been using.  Place a 1.4 lens in the camera and look at the beautiful feed that will result by using a professional camera and optics system to make you look better.

Lumix Camera as a Webcam what you need:

Cameras supported on the first release of the Beta.
(Note you will need to input your camera serial number to download the software)

  • DC-S1R
  • DC-S1
  • DC-S1H
  • DC-GH5S
  • DC-G9
  • DC-GH5

Official Computer Requirements:

  • OS: Windows 10 (32bit/64bit)
  • CPU: Intel CPU of 1 GHz or higher
  • Display: 1024 x 768 pixels or more
  • RAM: 1GB or more (32bit),2GB or more (64bit)
  • HDD: Free space of 200 MB or more for installation
  • Interface: USB 3.0/3.1

It is good to see the Lumix GH5 on the list as it is one of the best Lumix cameras for video recording ever released and many of our readers own it.

In order to get the video feed to get routed to your video conferencing software you are going to need to install these three programs in your Windows 10 PC:

  1. The Luimix Tethering Software Beta!
  2. OBS Free Open Source Video Capture Software!
  3. OBS Virtual Cam Plug In!

The excellent video below by Richard Wong will guide you through the steps to do this properly and activate the software for a variety of uses.  Support Richard by subscribing to his great channel here!

Setup your Panasonic Camera for Live Streaming / Webcam (GH5/G9/S1/S1H..etc) by Richard Wong:

Things to think about:

Make sure you have enough battery. On our test GH5 we needed to have battery power or AC connected for it to work as USB power is not available.  If other cameras can do it from the Linux Family it becomes easier as the PC can feed power essentially forever while you video chat.

There is some lag reported by users as the PC is taxed by capturing the video bypass and encoding can create a delay for webcam uses.  It is all a function of the speed of your computer here and the faster the better.  It would be ideal for Panasonic to allow for direct webcam pass-through from the Lumix cameras to video streaming software without requiring OBS. By using a driver the camera would show up as a webcam option without configuration steps. Lag should also be eliminated. This however is a workable solution and great first step.

The software as of now is only available for Windows 10, Mac OS and Linux support is not yet here and we hope it does in the future. Windows is being used as a testbed for bugs and once it is stable and solid enough we could see it being ported to at least Mac OS X.

Enjoy your new professional streaming solution and wow your boss, co-workers, friends or family with a beautiful image.  -HSC

P40 Pro Super Slow Motion extends Huawei’s reign!

P40 Pro Super Slow Motion

Last year the Huawei Mate 30 Pro was our slow motion phone of the year with its real 1920fps 720p with interpolated 4x mode to 7680fps and real 960fps at full 1080p. Now Huawei has again brought back the same performance with an even better optical system and what looks like better interpolation algorithms to the new P40 Pro and Pro Plus phones.

The phones have gathered little attention outside of China as Android cannot be updated and the Play Store is not accessible due to US restrictions on Huawei as a technology company that poses a risk to national security. Most of these phones are acquired by the use of importers or the pre-owned market and no US carriers offer them. Still, it is the amazing hardware design and the best slow motion performance on any phone to date that makes it impossible to ignore.

P40 Pro Plus Camera Specs:

Back Module Five on Plus

4x on Pro

50 MP, f/1.9, 23mm (wide), 1/1.28″, 2.44µm, omnidirectional PDAF, OIS
Periscope 8 MP, f/4.4, 240mm (telephoto), PDAF, OIS, 10x optical zoom
8 MP, f/2.4, 80mm (telephoto), PDAF, OIS, 3x optical zoom
40 MP, f/1.8, 18mm (ultrawide), 1/1.54″, PDAF
TOF 3D, (depth)
Features Leica optics, LED flash, panorama, HDR
Video [email protected]/60fps, [email protected]/60fps, [email protected], [email protected], HDR; gyro-EIS
SELFIE CAMERA Dual 32 MP, f/2.2, 26mm (wide), 1/2.8″, 0.8µm, AF
IR TOF 3D, (depth/biometrics sensor)
Features HDR
Video [email protected]/60fps, [email protected]/60fps

It is important to note that only The Pro and Pro Plus will have the full slow motion capability. The regular P40 has 3 camera modules and a top slow-mo spec of 960fps at 720p, missing the best features. The best value in our opinion will be the P40 Pro non-Plus version but if you can afford the Plus, by all means, it may be the phone to beat.

The Phone largest sensor is 50MP at 1/1.28 inches but that is reserved for stills and regular video. The sensor used for Ultra slow motion is the 40MP 1/1.54″ sensor which looks similar to that of previous phones.

We see improvements in processing and the AI interpolation is doing an incredible job of extrapolating 1920fps of real 720p data and slowing that by 4x to 7680fps. The end result has much fewer artifacts than the Mate 30 Pro especially in occultation background objects.  It is of course not flawless as interpolation as of now is no match to real captured frames.  Anything with a busy enough detailed background will create distortion and mush artifacts that are not valid for any scientific experimentation. You will have to cap the phone at 1920fps 720p or 960fps 1080p for real frame capture.

We were able to find very cool samples of the phone shooting slow motion below:

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

– 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.

Blackshark 2 Pro – 1920 FPS Slow Motion Video by Shail 360:

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
