High Dynamic Range. Heard of it? Canon recently released a white paper on HDR written by Canon Fellow Larry Thorpe, laying down the key concepts and preoccupations regarding this emerging technology. HDR. You’ve probably seen it advertised all over the place: on the latest generation Atomos recorders, on silly smartphone apps that take the High Dynamic Range look way over to the extreme, on new televisions and monitors claiming to be HDR Ready… It seems like its something we should want… but what is it? In his recent white paper about HDR, Senior Canon Fellow Larry Thorpe explains the trends in advancements in imaging technologies, and the main 5 parameters in which there has been particular preoccupation. As you can see, it is clear how improvements in each of these parameters translate to recent technological advancements (i.e higher frame rates and bigger resolutions). When it comes to contrast, it is important to understand that the Human Visual System (HVS) can simultaneously perceive details in both high brightness and shadow portions of the image, while at the same time being capable of perceiving much higher brightness levels than what current display technologies can offer. The Atomos Shogun Flame, one of the many current products offering HDR In an effort to further approximate to the abilities of the HVS, technologies are emerging that do indeed provide a much higher brightness, a clear example of this being the much higher nit count of current top-range recorders and monitors. However, this is not all that High Dynamic Range has to offer. As Larry himself puts it, this increased brightness is accompanied by a significant expansion of dynamic range – where both the brightness of the highlights and all their associated details are elevated to better emulate the real world, while at the same time the display can also portray details in deep dark portions of a scene.” While many people stay away from white papers due to their often very technical nature and language, I truly recommend you take a look at this Canon HDR paper by Larry Thorpe. It is a short, concise and clear effort to establish what HDR means from the viewer’s perspective, with enough tech talk to explain how this feature integrates in the greater scheme of imaging technology. If you have 10 minutes to spare, I’m sure you will find something interesting to take away from it. You can check out the Canon paper here. Also, do check out our talk with Larry earlier this year at NAB 2016, where we discussed the Canon C300 II and the release of the Canon Cine Zoom 18-80mm T4.4.Read more

Atomos Firmware Update 7.1 has been announced for the Flame monitor/recorder line. The update brings support for JVC and Red log signals, as well as PQ in/out and improved HDR features. The Flame line are the latest in-field monitor/recorders from Atomos. Check out our Atomos Shogun Flame review here. Atomos has improved the feature and support list for the flame recorders/monitors with firmware 7.1, with now the entire RED camera range covered as well as J-log from JVC cameras. PQ in/out is now supported meaning the Flame recorders can accept a ST2084 signal from compatible HDR camera or computer, and Color Mapping has been improved, increasing performance in the blacks. In terms of new features, the update mostly surrounds the AtomHDR mode of the Flame recorders. Previously AtomHDR was an on/off function with a slightly ambiguous ‘viewing environment’ slider. This has been replaced with a Scene Brightness Range which is meant to increase/decrease the dynamic range of the HDR view, starting from Rec709 up to full HDR mode (graphics display in percentage how much you are over Rec709). The new slider is accessible in the menu and on full screen view, with the addition of a clipping graticule (yellow line) on the waveform to signify where the additional dynamic range view is placed. You can also hit Auto HDR to set the clipping graticule to the maximum luminance level of your scene. Other additional features include slow motion playback. This is a nice feature and one I hope takes advantage of native higher speed recordings such as 50/60p from the Sony Alpha Cameras and plays them back in smooth slow motion (great when a client asks to watch that back and you have to explain that you can slow it down in post). There are 5 different speeds to this mode. Atomos has added back in a missing feature from their previous recorders; the ability to prioritise your power source (top/bottom battery or DC input). This is great for organising your power mode, specifically if one is powering an accessory like a wireless transmitter and you want to reserve as much juice from that particular battery as you can. Atomos Firmware Update 7.1 is available for download now from the Atomos website.Read more

At this year’s NAB show, Atomos released their new Flagship recorder, the Shogun Inferno. This device is capable of 4K RAW and almost everything else you could ask for when it comes to recording a high-quality video stream. The Atomos Shogun Inferno In our NAB video above, Nino chats with Atomos CEO & founder Jeromy Young, who takes us through Atomos’ new 4K RAW recorder in a little more detail. We already covered the Shogun Inferno extensively in our previous post, so be sure to check it out! Otherwise, as a quick reminder, here’s the list of features: AtomHDR; AtomHDR lets you shoot with the high brightness range of your camera’s Log profile and preview the final, vibrant post-production HDR result. 4K 60p; Record and play out pristine ProRes/ DNxHR in 4K resolution and 24/25/30/50/60p frame rates. HD 240p; Apart from 4K recording, high frame rate HD from 50p to 240p can be recorded from cameras that output these high frame rates. Quad SDI; The Quad SDI inputs let you connect from cameras with 1.5/3/6/12G SDI outputs without the need for converters. Raw recording; Capture the 4K RAW output from Sony FS7/ FS700 and Canon C300MKII/C500 over SDI, recording to either ProRes, DNxHR or CDNG. 10-bit monitor; 10-bit monitor processing increases the number of colors from 16.7 million for standard 8-bit panels to 1.07 billion, minimizing color banding on screen. 7” 1500nit brightness; For Standard Dynamic Range (SDR) shooting ramp the brightness slider up to 1500 nit for hood-free outdoor monitoring. Apple ProRes & AVID DNxHR recording; Record to visually-lossless Apple ProRes or AVID DNxHD in Rec709 or Log formats as an edit friendly, visually lossless industry benchmark independent of the camera brand used. PQ in/out; Take PQ out into larger HDR compatible screens or feed HDR from your NLE into the PQ input for HDR grading using the Inferno. Custom looks; Apply a custom look to footage by uploading and applying “.cube” 3D LUT’s. View in full/half mode on screen, output it to a monitor or record into the footage. Continuous power; Our patent pending Continuous power system automatically swaps to the second battery when power is low for uninterrupted recording in the field. Playlist generation; Create playlists easily, either entire clips or tagged parts of clips, for playback on the unit or out to a larger screen. HDR upgrades on other Atomos recorders Atomos has announced another cool update to their line of recorders: HDR support for the better part of their lineup of recorders. This means that even if you own an older model, such as a Ninja Blade, this (software) update will enable your device to display HDR content. The whole range of compatible recorders for the HDR update This is a really nice move from Atomos since many companies would leave their previous products lacking, in an attempt to increase sales on their new line. Instead, Atomos maintains compatibility with older models (within the range of given hardware limits, at least). So if you don’t need all the features of a Shogun Inferno recorder, maybe you could grab an older model and still get all the latest (compatible) updates. Get all the details about the new Shogun Inferno on the Atomos website.Read more
