### Core

- Intel QuickSync Video encode and decode support (beta)
  - Windows only currently; we hope to bring this to Linux users in the future
- DXVA hardware decode support (experimental)
  - Windows only
  - Suitable only for slower machines so disabled in preferences by default
- Choice of scalers
  - Lanczos
    - HandBrake's default scaler
  - Bicubic (OpenCL) (experimental)
    - Available on the Command Line Interface (all platforms) and Windows GUI (Mac / Linux GUIs will come in a later release)
    - Currently only available in OpenCL form so requires an AMD or Intel GPU supporting OpenCL 1.1 or later; Nvidia GPUs 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 each chroma channel (Cb, Cr)
  - New NlMeans denoiser, very slow, but results are significantly better than hqdn3d
- Presets

  - mpeg2dec has also been replaced in favour of using libav
- The LibAV AAC encoder is now the default as FAAC has been remove
  - 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
  - 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
- Removed mcdeint deinterlace and decomb modes (this relied on the snow encoder in libav which has been removed by upstream)

- Added resizeable update window
- Fixed parsing of non-DVD source audio formats
- Restored Copy to Clipboard to the Activity Log Window, among other enhancements to it

### A special note on the new presets (they're collapsible-triangle-folder-thing-errific!)

- Deux Six Quatre, Blind, Broke, and Bedlam are gone. They were dead weight.
- iPod Low-Rez is now iPod Classic & iPod Nano
- iPod High-Rez is now iPod Legacy
- iPhone / iPod Touch is now iPhone & iPod Touch, so take care CLI users
- Animation and Television now use the decomb and detelecine (VFR) filters
- High Profile presets now use psy-trellis and the new subme 9 mode with B-frame RD refinement
- AppleTV is now CRF, so sizes will vary with content
- PS3 preset should be fixed
- Constant Quality Rate still needs its quality % lowered, probably

The keen reader is already asking "iPod Legacy? WTF is iPod High-Rez called iPod Legacy now?"

The answer is Universal.

The Universal preset is designed to play on all modern iPods (anything newer than the iPod 5.5G). It also plays on iPhones. It also plays on AppleTVs. It should also play just about anywhere else, hence the name. It is full anamorphic DVD resolution--no tricks with downscaling like stuff from the iTunes Store. It includes chapters, and has the first audio track in both AAC (DPL2 downmixed) and AC3 pass-thru, just like the AppleTV preset. In fact, it should give the same quality as the AppleTV preset, but faster...and at a larger file size. Like the AppleTV preset, it used CRF, so sizes will vary.
