HandBrake (64-bit)

What's new in this version:

General:

Core:
- Intel QuickSync Video Encode / Decode support: Windows only currently. We hope to bring this to Linux in the future but not for 0.10
- DXVA Hardware Decode support (Experimental): Windows Only. Suitable only for slower machines so disabled in preferences by default
- Removed mcdeint deinterlace and decomb modes. This relied on the snow encoder in libav which has been was removed by upstream.
- Bug fixes and Misc Improvements

Choice of Scalers:

Lanczos:
- HandBrake's default scaler

Bicubic (OpenCL) (Experimental):
- Available on the Command Line (All Platforms) and Windows GUI. (Mac / Linux GUI's will come in a later release)
- Currently only available in OpenCL form so requires a AMD or Intel GPU supporting OpenCL 1.1 or later. Nvidia GPU's are not currently supported
- When downscaling, up to 5% performance improvement can be achieved. No benefit when not downscaling
- Small loss in quality over the Lanczos scaler

Denoise:
- hqdn3d filter now accepts individual settings for both chroma channels (Cr, Cb)
- New NLMeans denoiser. This is very slow, but results are significantly better than hqdn3d

Presets:
- Added Windows Phone 8 Preset

Updated Libraries:
- x264 r2479-dd79a61
- Libav v10.1
- libbluray 0.5.0

Libavformat is now used for muxing instead of mp4v2 and libmkv:
- "Large File Size" checkbox has now bee removed for mp4, as the new muxer will transition to 64bit files automatically
- mpeg2dec has also been replaced in favour of using libav

The LibAV AAC encoder is now the default as FAAC has been removed:
- This encoder is adequate for most, but until it improves a bit further, we have enabled support for the FDK-AAC encoder also. This FDK option is a temporary measure until the LibAV encoder improves. Note that FDK-AAC is much slower and will likely bottleneck the encode process, but will produce better quality audio

H.265 encoder
- is now available through x265 1.4. While this encoder is still fairly new, we have seen some promising results come out of it. It's still under heavy active development and is only going to improve over time!

Added VP8 Encoder (using libvpx)
- Available in MKV files only

Windows:

Accessibility / Usability Improvements:
- Added option to 'Use System Colors'. The app should now be more usable in a High Contrast mode
- Fixed Tab ordering to make the app more keyboard friendly

LibHB is now used for scanning instead of the CLI:
- Experiential Preview window is now available as a result (Can be enabled via preferences)

Improved the layout and design of the Audio and Subtitle tabs:
- Split buttons similar to the old 0.9.8 WinForms? GUI
- Improved layout on the track listbox to make better use of the space

Improvements to Auto-Naming feature:
- When Done: Added an option that will reset this to 'Do nothing' when the app is closed and restarted

Presets:
- New 'Presets' Menu
- Presets bar can now be hidden if it's not wanted

Numerous bug fixes:
- Fixed the Issue in the source dropdown where the drive menu items did not work when clicked
- Numerous fixes in the Picture settings panel around resolution calculation
- Numerous fixes around the way Presets are loaded and saved, particularly around Picture settings
- Removed Growl for Windows support due to bugs and issues with this library that remain unfixed. Project appears abandoned
- Many misc other fixes
- Windows XP is no longer supported. Windows Vista with Service Pack 2 or later is now a requirement
- The 32bit build of the application is now considered deprecated. This is due to 32bit process memory limitations

Command Line Interface:
- Basic support for return codes from the CLI. (0 = No Error, 1 = Cancelled, 2 = Invalid Input, 3 = Initialization error, 4 = Unknown Error")
- Bug fixes and Misc Improvements
