MediaCoder now with native 10-bit pixel depth support (Stanley posted on October 14th, 2016 )

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. mc_10bpp_1 mc_10bpp_2 Download latest MediaCoder

MediaCoder updated with NVENC 7.0 and Intel MSDK 2016 (Stanley posted on September 24th, 2016 )

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 (Stanley posted on April 23rd, 2016 )

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 released with NVENC 6.0 (Stanley posted on January 10th, 2016 )

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. mc_settings_nvenc_6

  • SDK samples no longer require the CUDA toolkit installed in order to build.

MediaCoder 0.8.37 released with NVENC HEVC encoding bitrate control issue fixed (Stanley posted on August 31st, 2015 )

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 0.8.32 released with multiple-pass H.265 encoding (Stanley posted on September 19th, 2014 )

In this release, 2-pass and 3-pass H.265 encoding have been added, and not many changes besides some routine update of codecs and minor bug fix. Anyway I know many people are demanding for the multiple-pass H.265 encoding. 😉 As always, head for the download page for the latest version.

MediaCoder 0.8.28 is released and a happy holiday! (Stanley posted on December 20th, 2013 )

MediaCoder 0.8.28 is just released. This version added support for VP9 encoding. Though the vpxenc is slow encoding VP9 with almost no multi-threading implementation (unlike VP8 encoding), MediaCoder's Segmental Video Encoding backs it up. With SVE enabled, the VP9 encoding speed boosts by times, though still low comparing to x264. Several other tools have been updated. An x64 build of MP4Box is included in 64-bit distribution. Several minor bugs got fixed. For GPU encoding, I fine tuned the pre-processing filtering parameters to eliminate some side effect I witnessed myself. For more info about the new release, just head for the changelog. Finally, I wish a happy holiday to all of my users! It's been almost 9 years since the very first spark and I have never stopped working on it. MediaCoder has served millions of people I believe. Thinking about all these, I feel my time and efforts spent throughout the years all worth it.

Splitting re-implemented in MediaCoder 0.8.25 (Stanley posted on August 14th, 2013 )

The splitting function finally comes back. There is no more "Split" mode. To enable splitting, simply go to Time tab for the splitting options (by time and by number of segments). The splitting operation is performed on-the-fly while transcoding is proceeding, so it's fast. mc_5550_splitting There are still some limitations though. Splitting currently does not work with multi-pass encoding and segmental encoding (SVE). The file relocation options are not working when splitting is enabled. These will be improved soon later.
