Video codecs
|
|
============
|
|
|
|
The following video codecs are available for encoding in HandBrake.
|
|
|
|
- H.264 (x264):
|
|
|
|
- MPEG-4 Part 10, also known as H.264/AVC
|
|
- Provides excellent quality, performance, and file size
|
|
- Widely supported by media players, including mobile devices
|
|
|
|
- H.264 (Intel QuickSync):
|
|
|
|
- MPEG-4 Part 10, also known as H.264/AVC
|
|
- Hardware based encoder available on Intel processors with Intel HD Graphics (Haswell or newer series CPUs recommended for best quality and file size)
|
|
- Very fast with significantly lower CPU usage than software H.264 encoders such as x264
|
|
- Produces larger (but usually not significantly larger) file sizes and slightly lower quality to an equivalent x264 encode, a trade-off that is typically acceptable, especially on lower performance systems
|
|
|
|
- H.265 (x265)
|
|
|
|
- MPEG-H Part 2, also known as H.265/HEVC
|
|
- Successor to H.264/AVC offering higher quality encodes and smaller file sizes
|
|
- Current strengths of x265 are improved quality and compression for low bit rate encodes, and for ultra high definition content
|
|
- Significantly slower than software H.264/AVC encoders
|
|
- Limited device compatibility compared to H.264/AVC, but this is improving rapidly
|
|
|
|
- MPEG-4 (ffmpeg):
|
|
|
|
- MPEG-4 Part 2, also known as MPEG-4 Visual
|
|
- Predecessor to H.264/AVC offering fast encoding with lower overall quality than H.264/AVC
|
|
- Compatible with older devices, inexpensive DVD/flash/network players
|
|
|
|
- MPEG-2 (ffmpeg):
|
|
|
|
- MPEG-2 Part 2, also known as MPEG-2 Visual and H.262
|
|
- Predecessor to MPEG-4 Visual offering very fast encoding with lower quality than modern codecs
|
|
- Creates larger files than modern encoders
|
|
|
|
- VP9 (libvpx):
|
|
|
|
- Developed by Google and the successor to VP8, VP9 is a free and open video codec
|
|
- Comparable to HEVC/H.265 in quality and file size
|
|
- Slower encoding compared to x265
|
|
|
|
- VP8 (libvpx):
|
|
|
|
- Developed by On2 Technologies and acquired by Google, VP8 is a free and open video codec
|
|
- Successor to Theora offering significant improvements, comparable to H.264/AVC
|
|
|
|
- Theora:
|
|
|
|
- Developed by Xiph.Org Foundation and based on On2 Technologies' VP3, Theora is a free and open video codec
|
|
- Comparable to MPEG-4 Visual in quality and file size
