H.265 VS VP9
VP9 or Video Processing 9, the successor to VP8, is an open and loyalty free video compression standard developed by Google. It is the Google's latest open source project whose target is to improve the delivery of content over the Internet. It is expected to reduce the size of the video files to half, comparing the current encoding technology called H.264 or MPEG-4. It will be used to compress video files and stream at 4K resolution.
Google has already announced that VP9 will be used for 4K content on YouTube. Google Play is also likely to use VP9 for streaming video service. When each individual service will have decided to send content using VP9, there must be some compatible hardware to run that content – which will be the big challenge for VP9. Google has already partnered with some companies like Intel, ARM, Broadcom, Marvell, Nvidia, Qualcom, RealTek, MediaTek, and Sigma for manufacturing VP9 compatible chips and components.
So it's reasonable that we should compare H.265 and VP6. The comparison between the two video encoding standards are listed below:
Type |
VP9 |
H.265 |
Name |
Video Processing 9 |
HEVC (High Efficiency Video Coding) |
Successor |
Successor to VP8 |
Successor to MPEG-4 AVC/ H.264 |
Developer |
Developed by Google as an open and free video compression standard |
Jointly developed by Video Coding Expert Group (VCEG) and Moving Picture Expert Group (MPEG). |
Improvement |
Bit rate reduction compared to VP8 is 40-50% |
Bit rate reduction at the same level of visual quality compared to H.264 is 40-50% |
Resolution |
Supports up to 8K (8,192x4,320) |
Supports up to 8K (8,192x4,320) |
Performance Comparison |
VP9 takes seven times less time to encode |
H.265 achieved 43.3% lower bit rate then VP9 |
Profiles |
two approved profiles |
three approved profiles, draft for additional five |
Industry Adoption |
Google has already announced that VP9 will be used for 4K content on YouTube and Google Play Video service. Google has already partnered with some companies like Intel, ARM, Broadcom, Marvell, Nvidia, Qualcom, RealTek, MediaTek, and Sigma for manufacturing VP9 compatible chips and components. |
Implementation demonstration across NAB, IBC, and other events starting 2012 companies e.g. ATEME, Broadcom, Thomson, Harmonic, Ericsson, Qualcom etc. Increased RD across encoder/decoder vendors for software and hardware based solutions. |
Year of Origin |
Initial release December 13, 2012 |
Approved in April, 2013 |
Drawbacks |
Transmission of UHD content might be a big challenge as the bit rate requirement is very high comparing to H.265 |
Approx. 300% more computational expensive due to larger prediction units and expensive Motion Estimation. |
Rayburn from Frost & Sullivan sated that HEVC can't be deployed until the full encode, decode and transport infrastructure is designed. The good news is that some major companies have already begun to adopt H.265. There were a lot of grumblings during the evolution of H.264 and the same will be true for H.265. H.265 will also have to face challenges from its competitor VP9. Above all, a lower data rate with the same quality is good for everything.
