The MainConcept HEVC/H.265 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, in accordance with ITU-R BT.2100.

With a unique all-in-one API for seamless access to software encoding, Intel Quick Sync Video and NVENC hardware encoding, the MainConcept HEVC/H.265 Encoder SDK is the perfect tool for all video compression challenges.

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 streaming formats for digital delivery, MainConcept offers SABET™, enabling efficient, simultaneous creation of multiple ABR layers in a single encoder instance.

The MainConcept HEVC/H.265 Decoder allows 8K120p real-time playback up to 10-bit 4:4:4 progressive and interlaced streams on dedicated systems. It supports the new professional Canon XF-HEVC format, packaging 4:2:2 10-bit HEVC/H.265 into an MXF container allowing existing workflows to support the same metadata as with current, AVC / H.264-based broadcast formats. 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 structures.

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



Supporting ingest, decode and playback of HEVC 4:2:2 10-bit progressive and interlaced files created by the new Canon XF 705 camera. The Canon XF-HEVC format, wrapped into MXF container, allows existing workflows to support the same metadata as with current, AVC / H.264-based broadcast formats.


Smart Adaptive Bitrate Encoding Technology (SABET)

Intelligent ABR encoding in a single instance by sharing processing data across up to 12 different profiles, reducing the 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.


Constant Rate Factor (CRF) Encoding

MainConcept’s HEVC/H.265 Video Encoder enables Constant Rate Factor (CRF) encoding. In this mode the user specifies a desired image quality and the encoder provides instantaneous feedback on the complexity of the source material, allowing for optimized bitrate ladder decisions and bitrate-efficient encoding with full HRD-compliance.


High Dynamic Range Support (HDR)

Signaling SMPTE 2084 based HDR-10 including SMPTE 2086 mastering display metadata and MaxFALL, MaxCLL. In addition, HLG transfer characteristics are signaled 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), 4:4:4 10-bit (Main 4:4:4 10), 4:4:4 12-bit (Main 4:4:4 12), and DVB-T2 all natively progressive or interlaced. Seamless hardware decoding support of H.265 video for improved CPU consumption with capable GPUs.
