MediaCoder 0.8.47 comes with native 10-bit pixel depth support. 3 color space options were added:
- I420 10-bit,
- I422 10-bit
- I444 10-bit
Formerly in MediaCoder, 10bpp video content are down scaled to 8bpp for processing. The native 10-bit pixel depth support is ideal for transcoding 10bpp content to 10bpp output. Currently only x264 and NVENC support 10bpp input. When encoding 10bpp H.264, make sure to choose correct profile on x264 tab.

MediaCoder 0.8.46 is released, with support for NVENC 7.0 and Intel MSDK 2016. Try some ultrafast H.264 and HEVC encoding with your cutting-edge GPU! Make sure to update your graphic driver to latest.
MediaCoder 0.8.43 is released with improvements on AviSynth decoding and MXF support as well as new revisions of x264 and x265.
Download latest release here.
MediaCoder 0.8.41 is released with NVENC 6.0. Two-pass encoding can be used with NVENC in MediaCoder now. Simply set video encoder to NVENC and rate mode to Two-Pass and you are ready to go. In advanced settings, you can find new option for 3 types of NVENC’s two-pass mode.
What’s New in NVIDIA Video Codec SDK 6.0
NVIDIA Video Codec SDK 6.0 adds following new features.
- Unified SDK for video encoding and decoding
- Windows 10 official support
- Support for H.264 Motion Estimation only mode
- Support for input surfaces in RGB format
- Support for SEI and VUI fields for H.265
- Support for Adaptive Quantization for improved subjective visual quality with H.265 (adaptive quantization for H.264 is already supported)
- GPUs supported for H.265 (HEVC) encoding
- GeForce GTX 960, GTX 980. GTX Titan X
- Quadro M4000, M5000, M6000
- Tesla M4, M6, M60
- Various quality and performance improvements in encoding
- SDK samples no longer require the CUDA toolkit installed in order to build.
MediaCoder 0.8.37 is released. In this release, the NVENC encoding bitrate control issue in ABR and CQP rate mode, which has been reported by many users who use NVENC to encode H.265/HEVC, is finally fixed. Other updates include upgrade of x264 and x265. MPlayer and MEncoder for x64 have also been updated to latest SVN revision. From this release, MediaCoder is built with Microsoft Visual Studio 2015.
MediaCoder is finally able to encode with NVENC, NVIDIA’s hardware SIP core that performs H.264/AVC and H.265/HEVC video encoding. NVENC SDK 5.0.1 is used, so NVIDIA GPU driver 347.09 or above is required. The latest version of SDK has added support for HEVC (H.265) encoding on GM20x GPUs (GTX980 and future Quadro/Tesla/GRID platforms based on GM20x GPUs). Following is the description of NVENC from NVIDIA’s official website.
The NVIDIA Encoder (NVENC) API enables software developers to access the high-performance hardware H.264 and HEVC (H.265) video encoder in Kepler and Maxwell class NVIDIA GPUs (See list of supported GPUs below).NVENC provides high-quality video encoding that is faster and more power efficient in comparison to equivalent CUDA-based or CPU-based encoders. By using dedicated hardware for the video encoding task, the GPU CUDA cores and/or the CPU are available for other compute-intensive tasks. NVENC on GeForce hardware can support a maximum of 2 concurrent streams per system. NVENC for GRID, Tesla and certain Quadro GPUs (see below) can support as many streams as possible up to maximum NVENC encoder rate limit and available video memory.
To test NVENC with MediaCoder, please install the latest MediaCoder Full Edition and install the following update.
Once the update installed, NVENC will appear in the video encoder list. Disable video encoder auto selection and choose NVENC and MediaCoder will encode with NVENC. The supported video format is H.264 and H.265 (if you have a GeForce series 9 card). Currently the configuration tab for NVENC is not yet done as the support for NVENC is just initial and is still being worked on. To adjust its parameters, click the “Encoder” button. More parameters will be adjustable in future updates. Have fun with the cutting-edge breezing fast hardware encoding with 10-year old MediaCoder.
