Hi10P

High 10 Profile (Hi10P), also just known as 10-bit. The newest standard for fansubbed and encoded releases.


What is Hi10P?

In really basic terms, more data is used to define color which means there is less banding for a smaller file size. It's an H.264 profile which uses 10 bits of information to represent color. It's a huge improvement because there is less file size, which in the long run saves bandwidth.

Advantages

  • Significantly higher compression ratios resulting in vastly decreased file sizes. In return, a huge amount of bandwidth is saved.
  • Far more information is preserved from the original, removing such issues as banding and poor detail in dark scenes.
  • Less things for the encoder to worry about.

Disadvantages

  • Slower decoding and encoding.
  • No support for DXVA or CUDA as of writing.
  • Slight compatibility issues with older devices during playback.

How NOT to play back Hi10P content

  • CoreAVC in CUDA mode, DXVA, LAV CUVID as well as the stable versions of VLC and ffdshow do not support Hi10P at the time of writing, because no graphics cards support 10-bit decoding
  • The SVN build of ffdshow-tryouts now supports Hi10P
  • Note: Using VSFilter (aka DirectVobSub) with Hi10P requires dithering material down to 8-bit first, which can introduce some quantization inaccuracies later on and also uses incorrect levels due to a bug in swscale (when using CCCP/ffdshow or LAV to dither)

Setup guide for MPC-HC + madVR

This method will result in higher image quality and performance than using CCCP (or anything ffdshow-based, really), so if you’re struggling to play back Hi10P anime, or even regular 1080p, consider trying this. MadVR and LAV are updated regularly and uses very new versions of libav for decoding as well as custom edits to make 10-bit decoding even faster, giving it much more speed than the ridiculously outdated ffdshow-tryouts project, and the even more ridiculously outdated CCCP codec pack that is based on it.

Setup - LAV Install

Step Zero: Prerequisites

Uninstall ALL instances of MPC-HC, CCCP, ffdshow, madVR, Haali, K-lite, CoreAVC etc. you might have on your system. This is a clean guide that requires no other prerequisites to function, and ideally should have none installed either.

Step One: Downloading and Installation

  1. Download and install the latest version of MPC-HC (you want the .exe version for an installer) Note: Get the 32-bit version (called x86) ONLY! The 64-bit version is incompatible with madVR and will not function at all.
  2. Install the LAV Filters. These are necessary for decoding video and audio. You need to select the Splitter as well if you don’t want to use Haali, otherwise you have to install Haali manually. (See image to right)
  3. Obtain and install the latest version of Haali’s Media Splitter
  4. Note: You can skip this step if your PC isn’t very powerful! Download the latest version of madVR and extract it anywhere you like. Run install.bat inside the folder. DO NOT DELETE THE FOLDER AFTERWARDS, madVR lives inside it and does not copy itself anywhere else. Move it somewhere sensible before installing, for example C:\Program Files\madVR.

Note: Make sure you’re logged in as an Administrator when running this! Do not right click and "run as admin", log in as admin and run it normally!

Step Two: Configuration

  1. Open up MPC-HC’s options menu. Under “Internal Filters”, disable everything. You can leave some of the ones on the left active, but make sure you’ve disabled all of the ones not selected here: Image
  2. Under Playback, enable “Auto-load subtitles”: Image
  3. Under Subtitles, make sure “Allow animation when buffering” is enabled, and “Maximum texture resolution” is set to “Desktop”: Image
  4. Under Output, choose “madVR” as renderer: Note: If you skipped madVR, or you’re experiencing lagging, frame drops or poor performance in general, set this to “EVR Custom Pres.”, “Haali Renderer” or “VMR-9 (renderless)” instead – try them in that order until you find one that works. Image
  5. Make sure the LAV Video is selected as default decoder. If in doubt, go to external filters, choose “Add Filter”, select LAV Video Decoder and switch it to “Prefer”: Image
  6. After making the above changes, restart MPC-HC and play back any file. You should notice the madVR icon in the system tray. Right click this to access the settings:

  7. Once inside, disable the “fullscreen exclusive mode” under Rendering -> General Settings. I recommend leaving this off unless you are having playback problems, because it prevents you from taking screenshots and makes the transition to fullscreen very ugly (It also messes up MPC-HC’s interface): Image
