Xiaomi Mi 11 Ultra Slow Motion Mode 1920fps Fake?

Xiaomi has surprised this year with now the Mi 11 Ultra phone which is a big step up from the Mi 11 released earlier this year. The huge difference lies in the size of the sensor which is close to a 1″ camera sensor like those found on the Sony RX camera series for example. The phone has two 48MP sensors and a main 50MP sensor for the main camera with a highly protruding camera bump that really screams for a case to be able to balance well on a flat surface.

The slow motion modes on the phone are rumored to be the garden variety with 120fps/240fps 1080p, 60fps 4k, and also a selfie camera that does 720p 120fps which is becoming commonplace. What is really peaking our interest is the 1920fps slow motion mode that is touted by some reviews. It is unclear what the phone is capable time-wise as the specs are still not all there. The samples we have seen show detail loss and the clear signs of interpolation. → Continue Reading Full Post ←

Z CAM E2 M4 Slow Motion With Affordable 4k 160fps!

Z CAM E2 M4 Slow Motion

The new Z CAM E2 – M4 Micro 4/3″ sensor cinema 4k camera offers performance that punches way above its own price weight of just $1,499 @ Adorama which is $500 less than the very similar regular Z CAM E2 just lacking Multicam synch support which is a very minor trade off considering the power and benefits you gain.   It has Triple native ISO of  80 / 160 / 800 and 13 stops of DR using their ZLog profile, and 16 stops of DR in WDR mode which does some HDR processing.

The frame rates are also outstanding for such a low-cost camera and while the higher setting requires H.265 encoding which for many is not ideal considering it lowers the bit depth from 10 bits to 8, it offers what many cameras only dream of.  160fps in 4k in beautiful resolution and up to 240fps in 1080p which has very good quality with some compromises.

So just from a specs point of view we can see the E2 being a real powerhouse with a variety of excellent options for shooters. If you also ad a speedbooster then you get APS-C like performance on a sensor that performs like that of the Panasonic GH5s with excellent quality up to ISO 6400-12800.

Z CAM E2 M4 Slow Motion how good is it?

The slow motion aspects for the Z Cam E2 M4 are class-leading with 160fps at 4k DCI and UHD with what we have confirmed to be pristine quality with no real artifacts besides H.265 compression. You will of course get 8-bit limitations on gradients and single shade subjects like blue skies but for everything else will be more than adequate.  See the beautiful sample below by Ludeman Productions of the E2 shooting in 4k at 160fps H.265.

ZCAM E2: 160p by Ludeman Productions:

When it comes to 240fps there is of course a trade-off that we have seen in the GH5s and other cameras that use this similar sensor design. The color, dynamic range, and frame rates are beautiful but you do get jagged edges on detail segments of the frame and especially lines with the characteristic stair-stepping of aliasing by the fact that the frames are captured by throwing out some lines.  It is still very good and for many users, it will be just as capable but if you value pixel perfection then the 240fps 1080p mode will disappoint purists.  See the samples below to get a sense of the quality offered here.

DJI Osmo Action Camera Slow Motion Initial Samples!

DJI Osmo Action Camera Slow Motion

The Introduction of the DJI OSMO Action camera marks what many called the ultimate silver bullet to counter the GoPro Hero camera line. It is an evolutionary step that takes most of what made the GoPro Hero Black series amazing and even goes further by improving in areas where GoPro has fallen behind. The Stabilizer seems better as is the addition of a secondary selfie screen in order to frame yourself while recording.

It gets the usual frame rates of 120fps & 240fps 1080p full HD and the 4k 60fps spec. None of these are revolutionary or groundbreaking which means this is a version 1 product for DJI.  Phones, for example, are already in the 960fps and 1000fps spec even when they are limited to fractions of a second. A Camera like the OSMO Action could have gotten a bit of this slow motion prowess and differentiate from GoPro even further but not this time around.  We have a few samples of the higher frame rates for you too look at and see if it makes sense to acquire this camera instead of other options.

OSMO Action Frame Rate Support List:

Video Rec 4K (16:9) – 60, 50, 48, 30, 25, 24fps
4K (4:3) – 30, 25, 24fps
2.7K (4:3) – 30, 25, 24fps
2.7K (16:9) – 60, 50, 48, 30, 25, 24fps
1080p – 240, 200, 120, 100, 60, 50, 48, 30, 25, 24fps

HDR Video 4K – 30, 25, 24fps
2.7K – 30, 25, 24fps
1080p – 30, 25, 24fps
OSMO Action Demo Video:

The OSMO Action is only as good as it needs to be in order to further slice the pie for GoPro and other competing action cameras. With more features that capture the selfie and Vlogger market, it could really replace GoPro for most users. We, however, think that GoPro will not be standing still and will at some point not only catch up to the OSMO Action’s new features but introduce some even higher specs in order to remain relevant.

For $349 USD the OSMO Action it is at least $100 USD cheaper than the best GoPro Hero 7 Black was at launch which leverages the Chinese manufacturing advantage to undercut GoPro’s US operations which carry a higher cost of research and assembly.  For most everyone, this difference in price is big enough to justify going all in with DJI gear instead of fiddling with other action cameras. Gopro Hero 7 Black is now $349 in order to compete with the OSMO.

In this excellent comparison video review, of the OSMO Action vs the Hero 7 Black by TEAMSUPERTRAMP you can clearly see that DJI’s Rock Steady beats the GoPro Hypersmooth by some margin plus it is also working on 4k 60p which the GoPro cannot do with their ultra-smooth mode. The DJI camera is actually more advanced as a gimbal replacement.

The dynamic range on both cameras is comparable but the OSMO Action is a tad sharper and less wide which may please some users. The Slow motion modes also look cleaner on the OSMO compared to the Hero 7 Black but not by a wide enough margin to justify one over the other. The GoPro tends to flicker more and has a UV blue tint on white surfaces which the OSMO Action seems to counteract by what we think is a treated UV element on the lens system which is also a great feature.

All Manual Control (Action First):

Yes the OSMO Action has a full manual control mode of shutter speed, ISO, and exposure mode which allow you to stop the camera guessing the correct exposure like abrupt indoor/outdoor transitions and from underwater to above water.  This is in our view one of the most important features of the camera and something we would like to see in GoPro cameras from now on. Manual exposure in Slow Motion is also a must to avoid motion blur as much as possible and get sharper footage.  DJI did a great thing by including this feature.

GoPro Hero 7 Black Has Killer Stabilization but Same fps!

GoPro Hero 7 Black

GoPro has released 3 new cameras including the Hero 7 Black which is now the flagship product for the company.  The key feature is HyperSmooth which is a predictive stabilization technology based on scene analysis and sensor telemetry to accurately anticipate motion and correct the image to generate a gimbal-like smooth appearance to the video.  When you see the footage it is clear it is a huge improvement compared to even the Hero 6 Black which had a pretty good stabilizer.

The Stabilization, however, is limited to  4k 30/60p and other resolutions below 120p but anything above 120fps will use the previous stabilization feature which is not predictive and have no stabilization support at all at 1080p 240fps which is the highest slow motion mode.  No 480fps or other higher fps settings are available as the camera uses both the same Hero 6 Black sensor and the same GP1 system chip for this new camera.

GoPro Hero 7 Black Frame Rate support:

4k Recording:

  • Wide FOV: 60,30,24 with HyperSmooth!
  • Super View: 30, 24fps

Introducing HERO7 Black – Shaky Video is Dead by GoPro:

There is no question that the Hero 7 Black is the best GoPro ever introduced. The quality and features are top-notch considering it remains an affordable $399.99(Available At Amazon Now) which is in line with other competitors.

The lack of above 240fps frame rates is disheartening as the spec has remained pegged to the camera since the Hero 5 black with only improvements in aliasing reduction and codec bit-rate. The footage does look better in the Hero 7 Black compared to the Hero 6 mostly due to increased bit-rate but not because the imaging system has changed because it remains exactly the same. The changes are mainly in the addition of a 1GB of extra RAM memory to help with Timelapse/Hyperlapse modes and the new HyperSmooth stabilizer. The extra GB helps the camera buffer enough information for real-time stabilization that is in a word unique.

This new stabilizer is so good that it really kills off gimbals for the Hero series like GoPro’s own Karma stabilizer which may still offer an edge but much less so now.  The Stabilization will, of course, reduce image quality with cropping but it does so intelligently by sampling a larger sensor area and then trimming as little as possible to maintain resolution across the board.

As mentioned earlier, the stabilizer will not work in 240fps slow-motion modes but many will point out that at that speed it will be overkill and redundant since stabilization in slow motion happens as a side effect of the high fps capture and regular speed playback.

Canon EOS R Is a Good Start But Lacks Frame Rates!

People waited with extreme patience for the Canon Full Frame Mirrorless line for several years. The Verdict? Pretty good start but feels like a mid-range product.  It lacks IBIS stabilization on the body sensor which has become one of the most coveted features for camera enthusiasts. It lacks dual card slots and most important of all for us it is 2014 frame rates for a camera of this class.

The camera does shoot 4k up to 30p but it has the same crop that has made the Canon 5D Mark IV a bad proposition for videographers that want 4k footage. The crop is 1.7x which is essentially a Micro 4/3rds sensor size with a speed booster but without all the benefits of those bodies like IBIS and very low rolling shutter with the added benefit of better frame rates. This feels for all intents and purposes like a base product for a line that needed to be released to compete but is still evolving technologically.

Canon EOS R Main Features:

  • 30.3MP Full-Frame CMOS Sensor
  • DIGIC 8 Image Processor
  • UHD 4K30 Video; C-Log & 10-Bit HDMI Out
  • 1080p Full HD up to 60fps
  • 720p HD up to 120fps
  • Dual Pixel CMOS AF – 5,655 AF Points
  • 3.69m-Dot OLED Electronic Viewfinder
  • 3.15″ 2.1m-Dot Swivel Touchscreen LCD
  • Expanded ISO 50-102400, 8 fps Shooting
  • Wi-Fi and Bluetooth, SD UHS-II Card Slot
  • Multi-Function Bar, Dual Pixel RAW
  • EOS EF Lens compatibility with adapters including ND

Canon EOS R Slow Motion Features:

Frame Rates: 3840 x 2160p at 23.98/24/29.97 fps
1920 x 1080p at 23.98/24/29.97/59.94 fps
1280 x 720p at 29.97/59.94/120 fps

Frame rates are capped at 720p 120fps which is so 2011 in some instances and quite unacceptable for a camera in this price range. The 60p max at full HD is also something that was all the rage back in 2013 but now feels geriatric by comparison to Sony, Nikon, Fuji and Panasonic products.

Red Hydrogen One Might Be Best Slow Motion Phone Ever!

Red Hydrogen One

The RED Hydrogen One phone has a lot to live up to but contrary to many doubters it may be just that good when it comes to video and photo quality. How good? By some accounts, it may be unrivaled by any phone currently and possibly for the foreseeable future thanks to the special software that is running on that last year’s Snapdragon 835 chip which is now outdated but still usable to create what RED touts as an imaging phone for the connoisseur.

We expect 4k quality in better codecs than the competition, with the ability to surpass 4k 60p which is the current phone upper limit for frame rates and resolution. As far as higher frame rates go we simply cannot find a lot of information when it comes to the way video is captured but read along to see something that may get a little closer to unraveling the mystery. New phone final body images have been released here in the forums.

Red Hydrogen One Is this the phone we have been waiting for?

As you can see in the image above which was found on the RED Hydrogen forum here there seems to be an ability to move frame rates on the phone to 120 and 240fps even in UHD and 2k cinema resolutions, but it could also mean that only the green portions are available for each resolution and the greyed out ones are not selectable as indicated by a commenter below. As to the validity of this, we will have to wait and see but it is quite encouraging to see an interface devoted to professional video options which take care to establish frame rates as a prime feature.

The Youtuber Marques Brownlee has also posted a Hydrogen One Prototype unboxing which you may find interesting and will give you a sense of what the phone is like physically.

RED Hydrogen One Unboxing! (Houdini Edition) by Marques Brownlee:

We do not venture on speculation much here at HSC but we will keep a close eye on the Hydrogen One and how it develops.  You may also like to see some of the posted image samples from the still camera module on the Houdini prototype phone in this pretty cool thread here: https://h4vuser.net/t/houdini-camera-quality/2027

RED has pushed back the Hydrogen One release date to 2nd of November 2018, with pre-orders beginning October 9th.

The Hydrogen One aluminum version will be available on these carriers: AT&T, Verizon, and Telcel for $1,295.00 USD. The Titanium variant will be out in 2019 and should be $200 USD More. More to come as the release date nears. -HSC
