The Lightspeed K80 was a ground-breaking GPU-acceleration server when released in 2015. As Telestream’s first dual-GPU server, it quickly became the bestselling Lightspeed of all time. After years of service at media facilities around the world, support for the K80 will come to an end on December 31st, 2021, so we are excited to offer a great incentive to upgrade to the newest Lightspeed, the G8.
Like the K80, the G8 is a single RU server, featuring an all-new CPU and dual-GPU architecture and is up to 80% faster than a K80 for certain operations. Despite the speed increases, the G8 is also up to 50% more power efficient. More speed, less power consumption, and being a drop-in replacement for the K80 makes the G8 a perfect upgrade.
Accelerated Video Processing
The G8 Lightspeed is a dual-GPU NVIDIA server that accelerates computeintensive image processing within Vantage workflows, including scaling, deinterlacing, frame rate conversion, motion vector calculation, and other tasks that require computation and analysis to modify, or create new video frames. Faster video preprocessing acceleration benefits the output quality of all video output formats, for both transcoding and automated content assembly.
Deinterlacing is required when converting interlaced broadcast content for web and mobile distribution and is also the first step in high-quality frame rate conversion. High-quality deinterlacing produces far sharper and clearer image quality than is possible with simple field blending techniques.
Video Image Scaling
Advanced image scaling is crucial to maintaining high-quality results. Both up-scaling and down-scaling require significant processing to preserve image sharpness. Lightspeed image scaling eliminates banding and ringing artifacts that are associated with video upconversion. This is particularly useful when converting broadcast content into web and mobile formats.
Frame Rate Conversion
Frame rate conversion is increasingly important for internationalisation and inverse telecine workflows. Lightspeed accelerates both standards conversion and the conversion of broadcast content to 23.976 film rates, with reliable, high-quality results. Tachyon® format conversion workflows are handled with speed and efficiency.
16-bit YUV Video Processing
Vantage employs Lightspeed technology to efficiently process 16-bit, 4:4:4:4, YUV video, achieving sparkling video quality and color fidelity for any Vantage output format. Lightspeed accelerates sophisticated image processing algorithms that have previously required purpose-built hardware to produce pristine video.
Accelerated x264 Encoding
Lightspeed Server also speeds x264 video encoding. x264 is renowned for producing the best video image quality across the spectrum of bitrates needed for screens of any size. Lightspeed accelerates x264 to produce the best possible H.264 images, at any bitrate, in the shortest possible time.
Accelerated HEVC Encoding
The G8 Lightspeed supports NVENC (NVIDIA’s HEVC Encoder) for certain Vantage transcoders, enabling encoding performance that is faster than x264 (but in most cases of lower quality).
