Chronos 1.4 RAW to DNG Tool Now Available!

Chronos 1.4 RAW

The Chronos 1.4 Team has now posted the first incarnation of the RAW Camera data to DNG File tool to convert the sensor information files to usable Adobe DNG sequences. They also have posted a sample image comparing the before and after characteristics of the image quality if saved on H.264 in camera and then the same scene shot and saved in RAW format which converted to DNG yields a substantial improvement in image quality as we explored in our previous post about this issue here.

The camera is expected to allow direct to DNG format file saving in the future but now you can shoot in the camera RAW format and later convert as an interim solution without sacrificing quality on the H.264 files.  Maybe in the future, the camera will be able to simultaneously save RAW and H.264 files as a proxy feature to be able to easily sample clips in editing before conversion.  We believe the DNG format should be your one-stop solution for this camera if image quality is important for your use case. → Continue Reading Full Post ←

Fuji X-H1 Aims to Compete in Pro Video!

Fuji X-H1

The Fuji X-H1 just announced does a lot of things right; It has a 200mbps 4k codec in UHD / DCI, 120fps Full HD which from the initial looks of it looks gorgeous and it finally has the 5-Axis Stabilizer on the sensor 5.5 stops worth that had eluded Fuji cameras for two years now.  It even has a new Eterna color profile which makes it easy to color correct without being too flat or too processed.

However, the X-H1 is based on the same 24MP X-Trans APS-C sensor found on the X-T2 which while overall good, it has problems with color moire and fine textures due to the processing on the unconventional RGB pattern which has 4 adjacent green pixels and differs quite a lot from Bayer sensors. See this article from PetaPixel comparing both technologies here.  But as far as video mode is concerned it looks to be a good contender to options like the GH5 and Sony 7 series. → Continue Reading Full Post ←

Panasonic TZ200 does 1080p 120fps!

Panasonic TZ200

Panasonic announced two new cameras this week the ZS200 America / TZ200 Europe  which offers the worlds longest wide to super zoom range in a 1″ sensor form factor with a 24-360mm equivalent F3.3-6.4 lens and the larger sensor 4/3ds 20MP “Same as GH5″ Lumix GX9 which tops out at 60fps 1080p which we will not cover any further. We have a cut off of 120fps for slow-motion cameras.  The ZS200, however, looks to be Panasonic’s answer to the excellent and full-featured RX series of cameras like the RX10 IV and RX100 V.

The main selling point of this camera is the appeal of carrying a 15X zoom in your pocket along with a 1″ sensor which beats most superzoom cameras that use tiny 1/1.8″ or 1/2.5” sensors.  Panasonic is able to do this by extending the lens to almost 3 times the camera’s width footprint including lens ring which looks kind of ridiculous but is effective at contracting enough to fit on a large pocket.   The image below shows only 3/4ths of the extension. → Continue Reading Full Post ←

Chronos 1.4 RAW Video Frame Samples!

Chronos 1.4 RAW

We received a set of Adobe DNG image samples from Krontech to check the resolution, dynamic range and grading potential of the camera when using the  RAW recording mode. As of now the utility to convert the raw data is still being tested but we were impressed by the results the camera was able to achieve by offloading the de-bayering process to a more capable converter like the Adobe Camera RAW module.

The Chronos files were already good when properly exposed but did suffer from some aliasing and moire in fine detail while resolution also took a hit by saving in a compressed H.264 format.  Now with the DNG RAW capability, we are glad to see that the camera image quality made an enormous improvement in the resolution, color fidelity, and dynamic range. It really brings out the real potential of the camera for a variety of applications, also creating a cleaner result in the noise department when processed correctly. → Continue Reading Full Post ←

Samsung Exynos Camera Rumor With Super Slow Motion!

Samsung Exynos Camera

The folks at Mirrorless Rumors have a new story based on an anonymous source that claims to know information about a super camera being tested at Samsung’s labs that can do among other things 480fps at 1080p resolution.  Its also claimed to be 4k 120fps ready and using the Exynos 9810 SoC which is reserved for their high-end phones up to now.

These claims are too detailed and too extraordinary to be believed but the Exynos Chip should be able to process all of that data.  The Rumor also states that it will be an APS-C chip with ISOCELL Technology on a stacked design capable of 30.1 Megapixels or 6720*4480px at 30p frame rates. The camera is a prototype according to the source and it is not known if it will be released as a real product in the future. → 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 ←
