Chronos 1.4 Firmware 0.3.1 b9 Unleashes New Features!

Chronos 1.4 Firmware

The Chronos 1.4c team based in B.C. Canada has been hard at work unleashing the features of the camera hardware and adding software features that should make the camera more valuable to video professionals everywhere. The new firmware adds HDMI live mirroring support for monitoring which is clean and lets you record its output. Another feature is the inclusion of native CinemaDNG save format image sequences which retain 16bits of color data and allow you to really streamline the workflow without time-consuming conversions.

In our testing over the last 4 days, we have really put the firmware “available here” through its paces and found very minimal issues in the software related to usability but no freezes and rock solid operation over around 14hrs of operation.   By saving to CinemaDNG we have no issues with cards getting write space errors due to saving the 1.8MB files individually. We feel this format is really unleashing the camera’s quality fully with a faithful sensor capture representation. → Continue Reading Full Post ←

iPhone Xs Slow Motion Official Apple Sample!

Apple has released a preview video showing the video capabilities of the iPhone Xs in 4k 30, 4k 60 and slow motion 1080p 240fps.  You can see in the liquid and sound part of the demo the quality delivered by the full HD slow motion but it is hard to judge per pixel sharpness and or artifacts from such a short high shutter video. We will need more real-world samples in order to see if there has been an improvement from the iPhone X of 2017.

We have isolated a part of the footage to see the slow-motion compression and we could detect aliasing in the edges, softness and compression artifacts which are typical of mobile phone high frame rates. The iPhone Xs seems to still have them to some degree. Color and motion on the codec seem to be excellent especially in 4k which looks extremely detailed and with more than acceptable dynamic range. → Continue Reading Full Post ←

iPhone Xs Slow Motion Lacks Improvement!

iPhone Xs Slow Motion

Apple just released 3 new iPhones and a 4th generation watch.  These are all about the screen and speed and not really big new capabilities. It is all refinement and flawless execution but video fans will look at these phones as a continuation of last year’s specs with a better codec and possibly better bit rates and image quality but not much else. The iPhone X and 8 still remain relevant which is expected in an “s” upgrade cycle.

Gone are the big leaps of frame rates and Apple is capping at 1080p 240fps while completely ignoring rivals like the Galaxy S9, OnePlus 6 and Sony Xperia XZ series when it comes to super slow motion video. Apple was at the forefront of these technologies with the iPhone 6 but now have really rested on their laurels while the competition leapfrogs in video capabilities when it comes to frame rates. Others will point out that even when the high speed is restricted you will now get better quality footage in all modes which is certainly an upgrade. → Continue Reading Full Post ←

Chronos 1.4 New Firmware Improves h.264 Image Quality!

Chronos 1.4 New Firmware

The Chronos 1.4 team has been hard at work on firmware improvements. The latest pre-released software patch shared with HSC improves the h.264 file quality at the pixel level by using a new demosaic algorithm to better match the real camera output.  We did a few sample tests to see how big an improvement it is and also to maybe ditch the slow and space eating RAW 16bit workflow which is our preferred file saving format as it retains all the sensor information.

The new improvements are already available to the community as a beta in this post. It is very stable it should immediately improve the way you work with the camera. Also, a new roadmap of upcoming firmware releases was shared in the forums which include HDMI monitoring and a complete OS change to Debian Linux from the current Arago distro for the camera which should improve development and speed in implementing features. → Continue Reading Full Post ←

GH5s Slow Motion Quality is Inferior to GH5!

GH5s Slow Motion

As expected based on early comments of the slow motion mode on the GH5s, the camera has pronounced aliasing “seen in this video by Max Yuryev” and softness the higher the frame rate goes. Even at 120p it is less detailed than the standard GH5.  It may be a function of supersampling in the higher megapixel  20MP GH5 vs the 10.2MP GH5s which is creating the new artifacts.

While the GH5s can shoot up to 192fps without cropping the sensor, anything above that up to 240fps it has a slight sensor crop which further decreases quality.  While the VFR mode on the camera is better than most cameras in the price range that attempt the feat, it is of note that the quality instead of increasing or remaining the same as the sister model takes a hit which may kill it as an option for slow motion needs.  We still believe the standard GH5 is the best Lumix option even when compared to the G9 in VFR mode. → Continue Reading Full Post ←

GH5s More Rumored Specs Emerge With 240fps!

GH5s

The latest info from 43 Rumors stemming from supposed leaks on the GH5s or “Low Light Version of the GH5” suggest a 10.28MP sensor with up to 240fps Full HD recording capability.    There seems to be an out of step rush to deliver this camera compared to previous releases by Panasonic which may or may not end with a product on the specified date of Jan 8th, 2018.

There has been a clear progression of frame rates from Lumix GH cameras from 60p to 96p, 120p and most recently 180fps with the GH5 and G9.  However, if the GH5s ships with 240fps we can safely assume that the spec will now be the bare minimum frame rate for a flagship camera in full HD instead of the 120fps most can shoot in high-quality mode.  The GH5 suffered from quality degradation above 120fps with aliasing and moire taking a toll. If the new camera can deliver 240fps with the same quality as 120fps then it will be a milestone mirrorless camera. → Continue Reading Full Post ←
