nablet mediaEngine adds powerful, simultaneous processing that enables encoding in several formats concurrently. Encoding to MPEG-2 XDCAM HD 422 while simultaneously creating a transport stream, proxy MPEG-4 file, and encoding to HLS is just one example.

It is perfect for live, OTT and VOD applications where incoming content needs to be converted efficiently to multiple formats. mediaEngine includes “while” function support for growing MXF files, enabling reading while writing – even in cloud environments.

mE is available for Windows, Linux, Docker and DirectShow. It comes as a command line transcoder, with an optional SDK also available for low-level integration into existing transcode workflows or applications.

A Windows GUI version called meXpress is also available, which is helpful for quickly testing speed and quality of the engine and the included nablet codecs and for quickly enabling various production scenarios.

mediaEngine has an integrated ultra-fast threading model that makes maximum use of the given resources. The transcoding speed is maximized as the built-in nablet video codecs are also optimized for the internal workflow. Optimized encoders and decoders for specific formats like XDCAM or XAVC provide further advantages compared to standard multi-purpose codecs.

nablet mediaEngine is designed to allow the highest possible scalability to set up cluster and cloud-based media processing and high-density transcoding solutions. It takes full advantage of GPU accelerated processing pipelines including Intel Quick Sync Video encoding, decoding, the NVIDIA NVENC encoder and other functions like high quality scaling, deinterlacing and many others.

mE supports all major formats and handles critical transcoding operations including:

• Format conversions between SD, HD and UHD
• Color space conversion including HDR
• High quality video denoising, de-/interlacing
• Highly optimized threading model
• Up to 8 Channel SDI to XDCAM HD in 1U server
• Up to 3 XAVC 4K Class 300 Encode on Intel Diamond

Other functions like XDCAM, XAVC and HEVC smart rendering are optional.
