For HDR to become widely available to live content producers – and therefore to audiences – a lot of these processes need to be simplified and automated. EVS’s Neuron, which was developed by Axon, moves beyond the LUT method for converting HDR and using a complex adaptive algorithm that frees up teams to concentrate on the production rather than having to craft the nuances of shading and light during the production. “LUTs are a static method, but they are very predictable. And conversions can be done entirely with LUTs, but you constantly need to be thinking about how the SDR is going to look when you’re producing the HDR. Sky and the BBC like to use LUTs, because they’re perfectionists. But for a lot of customers who don’t have the time or money, this adaptive method can be the way to go,” says Schut. Using archive material (likely to be SDR) in an HDR workflow is another reason to have an efficient HDR conversion solution. This also requires a good way to instantly identify which shots are SDR and which are HDR. On top of that, there are different flavours of HDR – HLG, Dolby Vision and SLog3. “This easy identification is one of the first things we’ve put into our HDR products,” says Sébastien
SOME OF OUR CUSTOMERS CAN’T DEVOTE ALL THEIR TIME TO BEING HDR EXPERTS Georges, vice-president of markets at EVS. “Some of our customers can’t devote all their time to being HDR experts. It can take a lot of energy and time doing configuration and testing to make sure you get the right conversion parameters set up. But dynamic conversion really makes that burden of configuring and testing a lot easier.” “Artistically, there is way more you can do with HDR,” adds Peter Schut. “But unfortunately, it still has to go back down to the old, fairly limited colour space for the majority of people to see it. And I think that challenge will be with us for a long time. But if it was easy, anyone could do it and they wouldn’t need us!”
