The MainConcept HEVC Encoder SDK offers comprehensive support for 4:2:0 Main and Main 10 profiles including support for BT.2020 enhanced color gamut as well as SMPTE 2084 based HDR-10, and HLG transfer characteristics signaling in accordance with ITU-R BT.2100-1. Depending on whether used on a 6th and 7th Generation Intel® Core™ Processor the encoder can leverage Intel Quick Sync Video technology for hardware-accelerated 8-bit and / or 10-bit operation and significant CPU load reduction. A similar option is now available for NVIDIA® GPUs to enable hardware encoding for dedicated systems turns the MainConcept HEVC/H.265 Video Encoder into the only existing all-in-one library for broadcast production workflows. The software encoder offers real-time 4K60 encoding for 8-bit and 10-bit profiles.

For solutions that cater to content preparation and transcoding into adaptive formats for digital delivery, MainConcept offers SABET™ enabling efficient accelerated encoding across profiles. The technology allows encoding of up to 12 output streams from a single source while maintaining equal high quality across all levels within an adaptive stream set by leveraging shared data.

The MainConcept HEVC/H.265 Decoder allows 8K60p real-time playback up to 10-bit 4:4:4 on dedicated systems. To obtain high-speed performance on supported low-end systems, the decoder offers a DXVA option to utilize GPU power for accelerated HEVC/H.265 playback on Windows. For HDR (High Dynamic Range) support, the HEVC Decoder fills dedicated HDR-10, HLG and PQ-10 data structure provided by UCC.

All-in-one HEVC Encoder SDK seamlessly integrates HW encoders from NVIDIA® and Intel®


Intel® Quick Sync Video hardware encoding is available within the MainConcept API as easy as an on/off feature. By leveraging Intel Quick Sync hardware with MainConcept HEVC Encoding SDK, CPU load is reduced significantly during video processing. For live encoding it is possible to achieve more parallel channels on one system.


NVENC hardware-based HEVC video encoding, available since NVIDIA Pascal GPUs, is seamlessly integrated into the MainConcept HEVC Encoder SDK with a simple API option. This enables HEVC encoding with a very small CPU footprint while improving processing speed or increasing the number of live channels per server. MainConcept HEVC Encoder SDK with NVIDIA NVENC is also supported in select cloud compute platforms.


Key Features

Efficient encoding of adaptive formats from a single source by sharing processing data across up to 12 different profiles, which reduces total encoding time by over 30 percent.


2-Pass Encoding

Up to 18% improved image quality compared to single-pass encoding with strict HRD- and target bitrate compliance.


High Dynamic Range Support

Signaling SMPTE 2084 based HDR-10 including SMPTE 2086 mastering display metadata and MaxFALL, MaxCLL. In addition, it supports HLG transfer characteristics signaling in accordance with ITU-R BT.2100-1.


Large Set of Decoding Profiles

Support of a many profiles in the MainConcept HEVC Decoder such as 4:2:0 8-bit (Main), 4:2:0 10-bit (Main 10), 4:2:0 12-bit (Main 12) and 4:2:2 8-bit (Main 4:2:2), 4:2:2 10-bit (Main 4:2:2 10) and 4:4:4 10-bit (Main 4:4:4 10), 4:4:4 12-bit (Main 4:4:4 12), DVB-T2. Additional, seamless hardware decoding of  H.265 video for improved CPU consumption if capable GPU available.

Boost MainConcept HEVC SDK with Intel® Xeon® Scalable Processors

MainConcept is always looking for ways how to improve performance of the HEVC Encoder and Decoder components by doing extensive testing on various platforms. Recently, MainConcept compared its HEVC SDK 8.2 on Intel® Xeon® E5-2699v4 @ 2.2 GHz x2 with latest Intel Xeon Platinum 8168 @ 2.7 GHz x2. The new Intel® Xeon® Scalable Processors provide up to 42% performance improvements compared to previous E5 generations. On the decoding side, our latest HEVC SDK achieves up to 58% speedup for the same format and resolution.


Looking at HEVC 8K 10-bit playback, the MainConcept HEVC Decoder even obtains a performance boost of up to 82% on an Intel Xeon Platinum 8168 compared to Intel® Xeon® E5-2699v4.

Powering production workflows and services with the latest Intel® Xeon® Scalable Processors results in significantly better quality for HEVC/H.265 4K live encoding or reduced conversion time for offline transcoding.
