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 ←

Nikon Stacked CMOS Sensor Will do 1000fps in 4k!

Nikon Stacked CMOS Sensor

Nikon Japan has been busy creating the next generation of 1″ stacked sensors.  The latest is a 17.84 Megapixel stacked design with hyper-fast memory interconnect that shoots up to 1000fps at 4k resolution which is no slouch. The sensor is still in development but it will be a possibility to see it in a camera that could compete head to head with the Sony RX series which now dominate prosumer P&S sales.  It was announced at ISSCC (International Solid-State Circuits Conference) held in San Francisco, February 15, 2021.

The sensor works by shooting in buckets of 16 x 16 pixels as one block, and then subsequently 264 x 264 pixel blocks (4224 x 4224 pixels) are conformed to form the final image at nearly 18MP.  It is unclear at this time if 4k video will be a windowed resolution or a supersampled then reduced final image from the full sensor.  The market for this sensor goes beyond consumer cameras as it is aimed at other applications like self-driving cars and production lines. → Continue Reading Full Post ←

BEST SLOW MOTION CAMERAS OF 2020!

BEST SLOW MOTION CAMERAS OF 2020

As the end of 2020 nears, it’s time to take a look back through the year’s camera releases amid the COVID 19 chaos, and see which delivered on the price/performance bracket with slow motion frame rates as the primary goal.  Phone slow motion took a back seat this year as the interest of the feature in phones was subdued or even eliminated. Our Best Slow Motion Cameras Of 2020 have been selected and ordered by recommendation!

We saw some surprises including a mostly affordable 4k slow motion solution and the adoption of 4k 120fps on many cameras which makes us think 240fps at UHD should be something to think about in the coming years as a regular option once 8k video is commonplace on consumer recording devices and TVs. The increase in resolution should theoretically allow for a lot of 4k frame rates to be offered as 8k delivers 4x the pixel count of 4k for any given frame rate. Keep on reading for our 2020 picks!

BEST SLOW MOTION CAMERAS of 2020:

Without further ado here are what we believe are the best value slow motion cameras in their respective categories for the year 2020:

Best Slow Motion Phone Category:

3rd Place) Sony Xperia 5 II:

The Sony Xperia 5 II is all about capturing the best video possible on a smartphone and in HDR. The kick here is that the phone is capable of 4k 120fps in full HDR which is pretty much class-leading.

The footage below will give you a taste of what the phone can do. In good light, it will let you capture excellent quality 4k 120p footage with the possibility to grade as it records a gradable flat profile.  In low light, it will be a pretty unremarkable image with grain and artifacts as could be expected from the light requirements when shooting at high speed.

Sony Xperia 5 II: 4K 120fps video footage by CNET Highlights:

Sony Xperia 5 II Slow Motion Specs:

  • 120fps 4k
  • 60fps 1080p

This is one of the first phones to offer 120fps in 4k which will probably become a standard spec in 2021 for flagships. However absent is the slow motion at 1080p which considering the 4k oomph, it should have been capable of 480fps at 1080p or similar. It is a shame that the spec was completely avoided considering HDR in 120fps 4k requires 240fps full pixel readout before merging.  In theory, 240fps non-HDR is possible on this phone but not available for unspecified reasons. Phones are becoming more powerful by the day and this is one that has our attention. The just under $1k price tag is not ideal but some of the best phones are going to cost you.

2nd Place) OnePlus 8T:

One Plus continues to offer compelling slow motion features on their phones with 480fps 1080p and up to 480fps at 720p.  It gives you a quad 48MP camera module which is literally insane considering the phone sells for under $750USD and has 120hz refresh rate. Feature-wise it has probably everything under the sun and then some and will not disappoint in the performance realm.

Wave Camera 4k Slow Motion Released for 10k USD!

The Freefly systems Wave camera has been released and it is certainly a market disruptor. It is not your average high speed camera since it is essentially using an internal SSD M.2 card to continuously record slow motion events it functions more as a live capture device than a shot by shot trigger traditional slow motion camera. This is essentially the idea behind the fps1000 camera line by Graham Rowan which sadly was dissolved last year. A new way of capturing high speed by leveraging the speed of SSD flash storage with ultra-high frame rates.

The Wave is no slouch in specs with a 4k spec of 420fps which is not as good as the Phantom Flex 4k which records 1000fps but costs a whopping 160k USD.  The Wave costs $9,995 and using an E-Mount with no power or AF functions, can be adapted to a variety of lens systems because of the plethora of adapters that can be used due to the short flange distance.  We take a look at the wave specs and why it may be the camera you were waiting for – if you can get one!

Wave Camera 4k Slow Motion Specs:

Continuous Capture Time:

  • 4096 x 2176, 422fps, 1TB 19min
  • 4096 x 2176, 422fps, 2TB 39min
  • 2048 x 1088, 1461fps, 1TB 23min
  • 2048 x 188, 1461fps, 2TB 45min

The camera uses a 4:3 aspect ratio from the sensor which is kind of odd but allows for a variety of frame sizes including anamorphic capture if stretch in post. This seems to be an ideal camera for Anamorphic slow motion.  Of note is that the Krontech Chronos 2.1 HD is also using a 4:3 sensor which in theory can be used with Anamorphic glass. → Continue Reading Full Post ←

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.

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:
