Codecs for Professionals.

HEVC/H.265 Video Encoding normally requires a decision between fast and good. The new MainConcept HEVC/H.265 Video Encoder SDK answers this question with: “Both”. By combining the software encoding quality for which MainConcept has been known for years with the performance of hardware processing, the latest HEVC/H.265 Video Encoder SDK offers unmatched encoding quality at lightning speed.

The unique all-in-one API for seamless access to software encoding integrates Intel Quick Sync Video, NVENC hardware encoding, as well as Hybrid GPU Accelerated Encoding on NVIDIA RTX graphics engines* to meet all requirements of video compression.

Support for 8- and 10-bit 4:2:0 profiles with HDR-10 or HLG in single- or 2-pass encoding can be optionally augmented with SABET™, allowing 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. In addition, the decoder offers several HDR processing algorithms that allow real-time PQ / HDR-10 to HLG, HLG to PQ / HDR-10 and PQ / HDR-10 to SDR conversion*.

* Hybrid GPU accelerated encoding, SABET™, Canon XF Ingest and HDR conversion are optional features.

MainConcept Hybrid GPU HEVC Encoding


The Hybrid GPU HEVC Encoder unifies MainConcept’s market-leading algorithms for bitrate control and quality software encoding with the unrivaled performance of NVIDIA's RTX architecture leading to the next generation HEVC processing. The Hybrid GPU encoding on standard server hardware balances between CPU and GPU processing while maintaining the expected high quality.

Key Features


Hybrid GPU accelerated encoding*

Combine the power of NVIDIA’s RTX Graphics engine with the quality and control of MainConcept’s encoding technology to accelerate video encoding without sacrificing quality.


Canon XF-HEVC*

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.


High Dynamic Range (HDR) Processing & Conversion*

Signaling SMPTE 2084 based HDR-10 including SMPTE 2086 mastering display metadata and MaxFALL, MaxCLL. HLG transfer characteristics are signaled in accordance with ITU-R BT.2100-1. The decoder also offers several algorithms that enable real-time PQ / HDR-10 to HLG, HLG to PQ / HDR-10 and PQ / HDR-10 to SDR conversion.


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.

* Optional features

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.
