Slow Motion Videos You Have to See!

Slow Motion camera releases are slow at this time of year but that doesn’t mean we have to be deprived of cool stuff to see. We have gathered a few slow motion videos that warrant your time and attention and surely push the art of capturing snapshots of time forward.

Even when these high speed cameras that in most cases are worth a lot more than the typical luxury midsize car, many creators are getting their hands on them and being creative in ways that could not be imagined in an earlier timeframe. From natural phenomena to technological feats, the footage has that mesmerizing quality that only this type of footage can instill on the viewer.  → 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.

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.

Krontech Releases Chronos Software 0.4 with LAN support!

Chronos Software 0.4

Krontech.ca the makers of the Chronos affordable professional high speed camera have released the Software version 0.4.0 Beta of the camera platform.  The cameras will now be using an embedded build of the Debian operating system which was already the default OS for the Chronos 2.1 HD.  All Chronos 1.4c cameras can now be upgraded to the new Beta version free of charge Follow this link for the official thread.

We tested the software briefly and found it to be responsive and solid.  However as a Beta, you should be ready to find some glitches here and there, if you are doing mission-critical work you should wait for a full release before updating to be on the safe side, we recommend it for most users who are not shooting once in a lifetime events. If you do find bugs please contact them to help squash them out.

Chronos Software 0.4.0 Software Beta:

Official thread, installation instructions and download link here!

Notable Changes:
– Support for the LUX2100 image sensor.
– API for camera control via JSON/HTTP over the Ethernet port.
* Examples: https://github.com/krontech/chronos-examples
– Saving of media over network to an NFS and Samba share.
– Software updates can be downloaded over the internet.
– Real-time video stream from the camera using RTSP.
– New back-of-camera GUI is available via the software update screen.
* For more information: http://forum.krontech.ca/index.php?topic=498

The biggest change is the ability to control the camera via Ethernet which gets it into more professional settings that allow for a really long tethering solution or using a small portable LAN Wifi router like the ZyXel here which will allow wireless control from afar. As of now it allows the use of control scripts that will operate the camera remotely with a great deal of customizability.  For situations that require the camera to be sealed and controlled remotely and unattended, this is an ideal solution. We will revisit the feature once we have tested it.

Spice Slow motion test chronos camera 2.1 HD by LaSt Studio:

We love the new Dark GUI and we especially find it comforting to get more video preview space which was taken by the old interface scroll bar and buttons. Now the video preview takes center stage much like what you see in other professional cameras like the ones from RED and or Blackmagic design.   We will test the new software in our next shoot with the Chronos 1.4 and will get a 2.1 HD to review later this year. Stay tuned!

Chronos does space science:

Krontech also shared this article in IEEE Spectrum magazine that details the work by Masten Space Systems on creating instant landing pads for future space exploration vehicles. The technology uses the rocket exhaust and composite materials to create a kind of lilypad array on planetary surfaces to create a stable base for exploration modules.

The Chronos cameras were used extensively for testing the different materials and exhaust plumes of rockets on their research. The footage below shows part of the Chronos camera imagery analyzing different test cases of the technology. We estimate the Chronos 1.4c was used for this project.

It is exciting to see Krontech catering to many labs now and creating a name for itself in the Aerospace industry by showing affordability does not necessarily mean unprofessional.  The fact that rocket scientists are using the cameras with great success should make it an easy purchase for many other labs.

Cronos HD 2.1 First footage samples surface!

Cronos HD 2.1 First footage samples

The team at Krontech.ca has been shipping the first units of the Chronos 2.1-HD 4/3″ Sensor high-speed camera to their customers and in turn, footage has started to become available online showing what this new super affordable 1080p slow-mo cam can do.  We will be reviewing a unit in the future once the firmware is more polished and will give it a good spin to finally rank it in our camera guide.

At first glance, we have a very positive reaction to the footage shown. The noise control and per-pixel detail are excellent and a clear cut above what the much smaller 2/3″ sensor on the Chronos 1.4c was able to deliver.   Larger sensors are a must for high-speed cameras to make use of more available light locations.   We have gathered some excellent video examples that will let you have a pretty good idea of what you can shoot and at what quality level with this camera.

Chronos 2.1 HD Main Specs:

  • 1080p, 4/3” format image sensor
  • 2.1 gigapixels per second
  • 1000fps @ 1080p
  • up to 24 046fps at
    lower resolutions
  • 8GB, 16GB and 32GB high-speed RAM buffer options for 2.7, 5.5 and 11.0 second record time respectively.
  • High sensitivity base ISO of 500 (Color) and 1000 (Monochrome) enables shooting with modest lighting.
  • l battery lasts for 1 hour of recording
  • Runs indefinitely on AC adapter or external power source
  • Many lenses supported: Nikon F, Canon EF and C mounts available as field-swappable options
  • Starting at USD $5,000.00
Resolution and Frame Rate Table as of February 2020 (Could differ in future firmware):

There is also a new monthly newsletter on the Krontech website so you are up to date with the news on these camerashttps://www.krontech.ca/chronos-newsletter/

Cronos HD 2.1 First footage samples:

A few notes before you look at these video samples: These are early beta firmware samples which means that the quality will probably improve from here in several aspects. The most obvious will be the vertical column banding artifact that can show up on higher frame rates and less than ideal lighting conditions.   We also see room for improvement in the color-science especially in reds and maybe some highlight tweaking.

However, at first glance, they look really good and a clear improvement from the earlier product from Krontech.ca the Chronos 1.4c.  This camera can now go head to head with much more expensive competitors as the image quality has increased greatly. Enjoy the samples!

BEST SLOW MOTION CAMERAS OF 2019!

As 2019 comes to a close its that time to take a look back through the year’s camera releases and see which delivered the goods at an affordable price in slow motion.  Phone slow motion continues to be a strong category, so strong in fact that we made a Best Slow Motion Phones of 2019 list that you can see here.

Stagnation in many camera segments aside from phones is still ongoing, the semi-professional and pro markets stay at 120fps and 240fps with the occasional 320fps camera that delivers just a tad better quality but at a price.  For professional slow motion, there were announcements but not a shipping product yet, however previously released cameras like the Chronos 1.4c and edgertronic still own the affordable quality market. Read on for our best of 2019 results!

BEST SLOW MOTION CAMERAS of 2019:

Without further ado here are what we believe are the best value slow motion cameras in their respective categories for the year 2019:

Best Slow Motion Phone Category:

We had 5 finalists for slow motion phone of 2019 and while the Mate 30 Pro below got the top marks, the iPhone 11 and OnePlus 7 series had great showings, go to the dedicated article for the rest of the phone options.

 Huawei Mate 30 Pro:

Coming out of left field from a company that has been in the news as being in trouble with the US government, the Huawei Mate 30 Pro which is not shipping in the US officially but can be found from online import sellers, is the slow motion phone champ of 2019.

Huawei Mate 30 Pro Slow Motion Specs Dissected:

  • 120fps 1080p Continuous
  • 240fps 1080p Continuous
  • 960fps 1080p for 1 full second (960 frames in total)
  • 1920fps 720p for 1/2 second  (960 frames in total)
  • 7680fps 720p interpolated 4x (lasts for 32 seconds on a 30p timeline.)
  • All super slow motion modes at 960p and above last 32 seconds of playback at 30fps regular speed.
  • The entire buffer for the slow motion feature is 2GB and gets filled by data then dumped and encoded on the fly by the Kirin 990 chip.

This is the first phone that truly records 1920fps slow motion in 720p mode for 1/2 a second or 960 frames and then does excellent interpolation to a whopping 7,680fps 720p to create mind-bending images.   It is especially good for people, animals, and hard non-deformable objects. It will of curse fail as any algorithm with fluids, powders, and heavily detailed objects and will create a soft mushy in-between frame in those cases.  If you do not choose interpolation mode then you can get real slow motion for up to 32 seconds of playback on a 30p timeline which is excellent for a phone.

If you decide to buy it, the phone has a few issues to keep in mind. Due to US government restrictions, it will not ship with a  full version of Android with the Google Apps and not have access to the Playstore.  However several workarounds have been worked out in forums to make this phone usable. The other is that it is a Chinese phone which may need you to get help from someone who understands/reads Chinese to make the setup and get to work in English after.    We do not recommend this phone as your main handset as the support of updates will probably be negated in the US but if you are in China, this is a great flagship phone.  If you are outside of China, make sure you can live with the limitations in the software.

960fps,1920fps and 7680fps test – Huawei Mate 30 Pro incredible Slow Motion by Slow Experiment:

As you can see from the sample above and these other samples at HSC, the quality is quite good and the time is usable easily as a sports and experimentation high speed mode.  It will of course not replace a dedicated slow motion camera for quality work but it is still an amazing development to get real 1920fps 720p and 960fps 1080p even with some artifacts in a portable device.

Huawei may be in hot water with the US government for some time but they have consistently delivered amazing hardware that is probably the cutting edge worldwide.  We are excited about the future of phone slow motion and considering the giant leap that happened here, it is not unrealistic to think that really good 1080p 2,000fps or similar could be very close.  At least for a small-time recording but it will really be magical.

Huawei has made an incredible slow motion phone on the Mate 30 Pro and if they read this, send a handset our way to test and offer samples of reference.  As of now, their new handset is the one to beat. -HSC

Mid Range Professional Cameras:

This year the semi-pro camera market had some very good surprises when it comes to cameras that can shoot RAW files at very high quality and also allow for windowed slow motion modes.

Two of our picks are from Blackmagic design which is a known name in the affordable quality camera market. They have been able to deliver RAW and compressed RAW with BRAW format for very little investment compared to many other brands.  The quality delivered by these cameras are really cinema-quality so the trade-offs when stepping down are more to do with changing a camera system for producers rather than giving up the footage grading ability or low light performance.

Third Place: URSA MINI PRO 4.6K G2

The URSA Mini Pro G2 had a firmware update mid-year that allowed for 300fps in a windowed 2k pixel mode that has great quality and can be stabilized for excellent 1080p production quality.  For under $6k for body only the price is not that high for a camera that can really bring your production values up.   It gets a third place because the cost of owning the camera goes up with accessories like media, lenses, batteries, monitoring, and storage for editing. A good kit can easily get in the 15k range. The BRAW format is excellent but not for everyone.  ProRes is also a possibility and probably what many producers will shoot in when need to deliver in a rush.

High Speed Frame Rates on the URSA Mini G2:

Blackmagic RAW 8:1

4.6K Full – Up to 120 fps
UHD Windowed – Up to 150 fps
HD Windowed – Up to 300 fps

With 4k UHD at 150fps it makes for a killer feature rarely available on other cameras and the 300fps in HD or 2k allows for that extra oomph within your creative shoot.
