Chronos Camera m43 Lens Adapter with Speedbooster Support!

Leave a comment

The two existing Chronos cameras, the 1.4c 720p at 1502fps & the Chronos 2.1 -HD 1t 1080p 1000fps are identical when seen from the outside but very different inside as they contain different sensor and memory boards. However one constant is that both use the C mount as the default for lens adapters. The camera usually comes with a Canon EF or Nikon F mount adapter depending on the buyer preference which screws on the C mount thread and allows for support of classic lenses from Macro to telephoto. 

One request from the community has been the support for other lens mounts like Micro 4/3ds which lets you adapt a variety of lens mounts and the much coveted speedbooster adapters which allow a 1 f-stop improvement in light gathering for micro 4/3ds systems. Today Krontech, the company behind the Chronos high-speed camera is introducing a passive Micro 4/3rds adapter for both the Chronos 1.4c and 2.1-HD and uses the body screw terminals near the lens thread mount to place a solid connection that allows such lenses. → Continue Reading Full Post ←

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

Leave a comment

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.

Z CAM E2 and E2 M4 Main Specs:

  • Dynamic Range13~15 Stops (Z-Log2) / 16 Stops (with WDR activated)
  • Sensor Type4/3″ WDR CMOS Sensor
  • Effective Pixels10.28M

  • Material  Aluminum Alloy
  • Weight  757 g (without lens)
  • Dimensions (W x H x D) 91.2 mm x 99.2 mm x 89.1 mm (without lens)

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.

Huawei Mate 30 Pro New Slow Motion Samples!

Huawei Mate 30 Pro New Slow Motion Samples

The Huawei Mate 30 Pro has been out for a few weeks outside the US, mainly in China and India and we have gathered 15 video samples from its slow motion mode which as of today is the best performing high-speed phone ever developed.  We had some shortcomings about the way the phone reaches the highly hyped 7,680fps mode which is 1920fps multiplied by 4x in software from a small snapshot of the video memory.

We also had some suspicions that the 1080p 960fps mode was also interpolated but looking at the samples we gathered it seems that was a premature call. The phone is actually capturing the full frame rate at 1080p or close to that.  The real max mode is 1920fps at 720p which is then interpolated to 7,680fps with good success by the new Kirin 990 chipset. Your mileage may vary and the results depend on the subject matter more than anything as organic slower motion looks much better than fast unpredictable bursts that break the interpolation algorithm.

Huawei Mate 30 Pro New Slow Motion Samples:

Make sure to read our previous post on the Mate 30 Pro to understand how the phone shoots video in high frame rates if you have some doubts.

The faster the motion and the more detailed the subject like water, sand or dust can break the algorithm easily and cause unwanted blurring. The phone is creating these frames from a 1,920fps video and creating in-between frames much like programs like Twixtor or Optical flow do it on your PC video editor see our article here on this subject to understand more.

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.

There is no doubt that the more light you give the phone the better capture it will achieve. The Phone has a maximum shutter speed of 1/4000 which is the default on a bright sunny day, if you shoot in that kind of light you have a better chance of avoiding blurring and the subject will have more detail while the interpolation system on the Kirin 990 will have an easier time doing the interpolated frames.

Huawei Mate 30 Pro Slow Motion The Real Story!

Huawei Mate 30 Pro Slow Motion

Huawei has just launched the Mate 30 Pro and Mate 30 Pro 5G Smartphones which sport an impressive camera module with a large sensor array that shoots at 40 Megapixels.  We had rumors sent a couple of weeks back but had our reservations due to the less than optimal slow motion in the P20 and other Huawei Smartphones.  The phone is now untouched by the competition as it can shoot a half-second at 1920fps 720p or 960fps total which translates to 32 seconds on a 30p timeline.

The headline slow motion feature of 7680fps is not real as it is derived from the 1920fps 720p half-second which the phone then uses AI selection to isolate a 0.12 seconds segment of the capture then finally interpolated by the Kirin 990 Chipset to the full 7680fps. So it does a 4x slow motion on top of it to get the great-looking result.

Huawei Mate 30 Pro 7860fps ULTRA SLOW MOTION DEMO!!! by DroidHolic:

Huawei Mate 30 Pro Slow Motion Specs Dissected:

  • 120fps 1080p Continuous
  • 240fps 1080p Continuous
  • 960fps 1080p for 1 full second (960 frames in total)

  • The entire buffer for the slow motion feature is 2GB and gets filled by data then dumped and encoded on the fly.

As you can see this is some serious phone performance and at this moment it is the slow motion champion for smartphones. It de-thrones Samsung, OnePlus, and Sony for the top spot by offering 960fps for a full second at 1080p and 1/2 second at 1920fps 720p. This is untouched performance.

Galaxy Note 10 Slow Motion Initial Samples!

Galaxy Note 10 Slow Motion

The Galaxy Note 10 is Samsung’s most expensive flagship phone yet and as it should be it is also the most capable. We recently saw some slow motion samples that we wanted to share and why this phone is the best quality slow motion a Samsung phone has ever been able to produce.  Sure the quality difference between the Note 10 and the Galaxy S10 is very small but it is there. We see less moire and aliasing than on the S10 and the detail retained is also better.

We were disappointed at first that 720p was still the top resolution for slow motion. But the only 1080p phone alternative the Sony Xperia Series like the Xperia One is only recording 0.1 seconds of slow motion at 960fps 1080p which is next to useless. Furthermore, the supposed 1080p quality looks just a tad better than the Samsung which is not particularly high quality either.

Galaxy Note 10 Improves Video Quality Above S10!

7 Comments

Galaxy Note 10

Samsung has released the Galaxy Note 10 and 10+ with even a 5G variant which was probably the most leaked phone of the year aside from the iPhone refresh coming next month. The phone has some beefed up specs and an impressive screen with a center cut upper camera punch-hole that love it or hate it is here to stay for now.

The video specs and photo specs look similar to the Galaxy S10 but with better color, dynamic range, lens elements and better overall video compression which looks very nice. The Galaxy S10 was no slouch in video mode but the Note 10 has the better compression and color processing that makes it a notch above. The slow motion spec remains the same as last year’s Note 9 and Galaxy S10 so Samsung is also stagnating in this respect.

Note 10 Video Recording Specs:

Resolution

  • 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 Slow-mo 720p video support at 960 fps
  • Slow motion 1080p video support at 240 fps
  • Hyperlapse 1080p video support

Other features

  • Super steady
  • HDR10+ recording
  • Zoom-In Mic
  • VDIS (Video Digital Image Stabilization)
  • Digital zoom up to 10x
  • High CRI LED Flash
  • Tracking AF
  • Take 9.1MP still photos while recording 4K UHD video
  • Playback zoom
  • Video location tags

Note 10 Slow Motion Spec by Samsung:

“Super Slow-mo only supports HD resolution. Users can record approximately 0.4 seconds of video captured at 960 fps with approximately 12 seconds of playback. Users can record approximately 0.8 seconds of video captured at 480 fps and digitally enhance the video to 960 fps with approximately 24 seconds of playback. Playback time can be edited in Super Slow-mo player.”

Samsung’s Galaxy Unpacked 2019 Event in 11 Minutes by CNET:

As you can see the Note 10 has the same slow motion spec as last Year’s Note 9 and Galaxy S9/S10 phones which is limited to 960fps at 720p for 0.4 seconds which translates to 12 seconds playback in a 30p timeline. You can double that to 24 seconds by shooting at 480fps for 0.8 seconds “Yippie almost a full second” <—Sarcasm!

Gone are the rumors of 1080p super slow motion and a higher recording time which were heating up by the fact that this new phone has 12GB of fast RAM which could allow for an impressive buffer but Samsung decided to keep it simple and translate the same spec as previous releases.

One area of note is that it appears the video quality is up across the full range of video modes by better noise/artifact handling and improved bit rate handling. The colors and motion look better than any Samsung phone before it. We found 240fps 1080p footage from the Note 10 in the video below that shows a marked improvement in color handling and edge sharpness without causing bad artifacts.
