ByteDance overseas technical team won the championship again: HD video coding has won the first place in 17 items

ByteDance video encoder , stay MSU 2020 In the competition , And got new good grades .

 

MSU 2020 It is the authoritative video coding competition held by Moscow State University in Russia , Recently published 4K And full HD video （1080p） Subjective score in the competition of two items , Video encoder independently developed by ByteDance （BVC） Got two latest achievements ：

 

• BVC1, The award for the 4K 8bit project 8 The first place in the scoring standard .

• BVC2, Be evaluated Full HD video （1080p） Subjective score offline 1 fps Best track Quality Award , Subjective score and 4 All the objective scores are first .

 

Plus before 2020 year 12 Full HD video released in August （1080p） Objective scoring items 1fps Racetrack 4 The champion of the scoring standard ,BVC Series encoder entered the competition for the first time 、 It took just 40 Days of optimization , Compete with leading companies in the video field , already Got this MSU 2020 Three major events 、 Cumulative 17 The first place in the scoring criteria .

 

BVC The main R & D team of series encoder is located in the United States San Diego ByteDance advanced video team , Team members graduated from the University of California, Santa Barbara 、 University of Illinois at Urbana Champaign and other well-known institutions , All have master's or doctor's degrees , It has been published in top international journals / More than 30 Papers , And get the global nearly 100 Authorized patents .

 

Many members of this overseas team also play an important role in many international standardization working groups , Such as VVC、H.265/HEVC、H.264/AVC Editor in chief and editorial board of many standard texts . In the past two years , Byte beat advanced video team submitted 260 Above H.266/VVC Technical proposal , Adopted more than 130 term .

 

With 5G And the deep landing of HD video scenes ,BVC Series of encoders have proved that they can meet the needs of video coding in high-definition scenes , Can be used as a boost 5G Infrastructure products for media applications .

 

To reflect the objective quality VMAF For example, indicators ,BVC Encoder in VMAF Compared with other participating encoders, the leading range of indicators is about 8%-15%. It means , Same quality video content , Use BVC Encoder can save for service providers 8%-15% Bandwidth and storage costs , When the network speed of the client is slow , Use BVC Encoder transcoding , You can also enjoy higher image quality 、 A smoother video experience .

 

Besides , In the competition BVC Series encoder is gradually integrating output for enterprise users , service B HD video codec demand in the end market .

 

 

 

4K 8bit champion

 

First look BVC1.

 

 

stay 1fps and 30fps Of the four scoring criteria ,BVC1 Have achieved the best results ：

 

PSNR avg.MSE（ A way to calculate the peak signal-to-noise ratio ）,1fps

 

The shorter the histogram is , It means that the smaller the size of the encoded file 、 The better the results 、 Users use less traffic

 

PSNR avg.log（ Another way to calculate PSNR ）,1fps

 

 

SSIM（ Structural similarity ）,1fps

 

 

VMAF（ Video multi method evaluation fusion index ）,1fps

 

 

PSNR avg.MSE,30fps

 

 

PSNR avg.log,30fps

 

 

SSIM,30fps

 

 

VMAF,30fps

 

 

 

 

offline 1 fps Best quality award

 

in addition , stay 1080p Video subjective evaluation , That is, judging from the subjective feelings of human judges watching the video , Byte runout self-developed encoder BVC2 Rated offline （1 fps） Best track Quality Award .

 

 

And in the 1080p Among the four objective criteria related to video ,BVC2 Also maintained the first place .

 

PSNR avg.MSE

 

 

PSNR avg.log

 

 

SSIM

 

 

VMAF

 

 

 

 

For the first time , Multiple project champions

 

In addition to the two events announced this time , stay 2020 Published at the end of the year MSU 2020 Full HD video （1080p） Objective scoring items ,BVC2 I also got 4 The first scoring standard .

 

 

Research and development BVC Series encoder ByteDance advanced video team revealed , This series of encoders are continuously updating iterations , And promote commercial applications , Meet the needs of HD video codec in the enterprise market .
