Soon we’ll know… Abbreviation, acronym and initialism As soon as we got one in our hands we will start to test it out in our lab. Getting better video codec support directly on the GPU card, like the Nvidia HEVC NVENC, is therefore very interesting, and later this month (sept 2018) Nvidia will release their 20-series GeForce cards which takes one more step further in a feasible price level. Amazon/AWS acquisition of Elemental some years ago seems to have been a smart move, since Elemental got quite long experience of GPU accelerated video encoding and AWS got plenty of GPUs waiting to crunch video data in the AWS cloud, but watch up for costs. The cloud encoding solutions got GPU possibilities, but struggles with bandwidth problems when 4K UHD source files moves along. On the other hand we see manufactures that packs the software in a hardware box and raises the price radically high. GPU encoding is one hot topic, especially talking about 4K UHD encodings where we see huge manufactures still a bit afraid of GPU video encoding since that will sell less encoding software licenses. In professional pipelinesĪs a transcoding agency, Pixlo have ongoing discussions with several manufactures about bugs and new features in video encoding systems. The larger resolution, the better performance compared to CPU as long as the disks can deliver frames to be encoded. Creating mezzanine quality HEVC encodings.If you have fast access to the source file to be transcoded.Large resolution encodings, like 4K UHD.Some short notes where HEVC NVENC is interesting to use: But it gives a hint of the GPU power on larger pixel resolutions. The numbers in the table above is just a quick lab test and should not be compared to a professional pipeline. ![]()
