Blackmagic RAW Codec Opens the Future!

Blackmagic RAW Codec

Blackmagic Design may have just solved the problem of RAW video capture for any camera and every type of user. In essence, it gives the benefits of RAW capture while allowing flexibility in file size depending on production needs.  It is a compressed format but by using a clever demosaic algorithm that happens in-camera, it shrinks the file size much more than other formats while preserving quality and RAW features like White Balance, ISO,  exposure,  NR, clarity and color bit depth.

For Slow motion cameras, it may be the codec of the future as it will allow the best quality without the enormous file sizes associated with image sequences like DNG or other RAW formats.  Being open source and free of licenses it aims to be adopted by the entire industry faster than other formats and will be free of the platform-specific nature of codecs like Apple’s ProRes which only works on Mac OS X.  The Blackmagic RAW beta is already available here! → Continue Reading Full Post ←

NVIDIA Slow Motion Interpolation With AI Deep Learning Tech!

NVIDIA Slow Motion Interpolation

NVIDIA has been hard at work on the problem posed by high frame rate interpolation of video data shot on lower fps.  We have had this tech since the late 1990s with the advent of Twixtor and refined over the decades in systems like Twixtor Pro and Adobe’s Optical Flow in After Effects. You are still not getting real temporal detail data since the frames are created by extrapolating velocity and direction vectors plus pixel values between frames to get the result.

We explored this technique in our post on interpolation here and why it is no substitute from a real slow motion camera solution.  NVIDIA’s new method uses machine learning along with 11,000 videos to arrive at a more convincing result. Considering the relatively small sample size we can imagine a future where hundreds of thousands or millions of footage samples are used to generate near flawless interpolation. This technique takes some serious computation and data sets so as of now it is not really ready for the mass market but that could change with the cloud very soon. → Continue Reading Full Post ←

CHRONOS 1.4 SOFTWARE V0.3 RC2 Released!

Chronos 1.4 Software V0.3 RC2

The Chronos 1.4c Team has released the latest v0.3 RC2 software for testing.  Be aware that this is not mission critical stable software so only use on your own private testing and not for recording mission critical shoots.  The Interface can now be flipped to the left side though we would love to see an option to be concentrated on the lower part for better screen real-estate distribution.

We have tested over the last few days and are happy to report that the software has been stable and rock solid with no lock-ups and no sluggishness.  The Color science was improved since the first v0.3 RC1 release to render the red colors among others more faithfully. In our testing, there was a definite improvement but we would like to see better treatment of the deep blues and magentas. We are happy to see White Balance is now supporting built-in presets! → Continue Reading Full Post ←

Chronos 1.4 Software V0.3 RC1 Released for Testing!

Chronos 1.4 Software V0.3 RC1

The Chronos 1.4c Team has been ramping up software releases with the latest v0.3 RC1 being dropped just a few hours ago.  Be aware that this is not mission critical stable software so only use on your own testing and not for recording once in a lifetime events.  The big fixes are in the color pipeline and how the camera handles pixel color especially red tones which were a little pinkish in previous software releases. It seems the entire color acquisition pipeline has received an overhaul. This should improve the color rendition on all objects plus the added benefit of less tweaking in post.

There are also several UI improvements like the ability to clear some warnings, move the button layout pane around the main interface screen and the ability to auto-save clips after shooting.   HSC will be testing the new software and report back when we get some new images.  We are preparing a color test to see before and after the software update and how much color has improved with the release. → Continue Reading Full Post ←

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 ←

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 ←
