Pegasys TMPGEnc 4.0 XPress Video Encoder to Use NVIDIA CUDA Technology                                                                                                                San José, CA - August 25, 2008 -




Pegasys Inc. (Ryogoku, Sumida-ku, Tokyo; CEO: Tak EBINE) todayannounced at the NVISION® 2008 visual computing conference, being heldAugust 25th to 27th in San José California, that it will use NVIDIA®CUDA™ technology to offload much of the processing required for TMPGEnc4.0 XPress from the CPU to the graphics processing unit (GPU). A betaversion of the software shows up to 446% performance increase over theCPU-only version.

                                                                                                                What is CUDA technology?
NVIDIA's CUDA technology is the world's only C language environment forthe GPU. It enables programmers and developers to create software forquickly solving complicated computation problems using GPU multicoreparallel processing capabilities. To date, NVIDIA has shipped over 80million CUDA-enabled GeForce® 8 Series and higher GPUs, the largestinstalled base of general-purpose, parallel-computing processors evercreated. The latest generation of NVIDIA GeForce GPUs offer up to 240processor cores, compared to a maximum of the four cores found on thehighest-end CPU. Any process that can be divided into multiple elementsand run in parallel can be programmed to take advantage of the massiveprocessing potential of the GPU.

                                                                                                                CUDA accelerates filter processing in beta version of TMPGEnc 4.0 XPress
Pegasys has incorporated CUDA technology for filter processing into thenew beta version of its flagship video encoding software, TMPGEnc 4.0XPress. "In a very short time we have been able to use CUDA technologyto offload decoding onto the GPU and we look forward to working withNVIDIA to expand it to the encoding, as well. Adding GPU support intothe filter processing was the best way to see a dramatic result in arelatively short time." (Comment by Tak EBINE, CEO)                                                                                                                
                                                         "NVIDIA CUDA technology hasalready made a substantial difference in the performance of TMPGEnc, avery popular creative video editing tool for consumers, yet we are justscratching the surface of the visual computing capabilities of NVIDIAGPUs. As Pegasys continues to offload more and more of thefunctionality to the GPU, we will see dramatic results that will be aboon for both video enthusiasts and casual home movie users looking forsimple and fast ways to edit, share, and enjoy their video," saidMichael Steele, general manager of visual consumer solutions, NVIDIA.

                                                                                                                                                                        Test results show impressive performance gains
In the beta version, application performance has been increased by upto 446% with CUDA technology, compared to the Intel Core2Quad Q9450, atop-of-the-line CPU. This demonstrates that CUDA technology will have amajor impact on encoding speed, which requires a lot of filterprocessing.

这个比较大头，期待CUDA带来的高效率。

boris_lee

这个有点意思了
津波是个不错的东西

hornbill

看截图，似乎仅仅在过滤和解码方面利用了CUDA，主要的编码环节还是CPU的工作

axelzq

E版兴奋的连发两贴啊{blush:]

来力

只用WisMencoder的路过~~~
看来CUDA准备大展宏图啊~~不错不错~~

MASSAGE

终于有实用的东西了，好

toshibacom

这个不错，比NV推出的那个转码软件好得多。

xzyzy

CUDA？真是孤陋寡闻啊

goldman948

有点常识吧,Badaboom跟TMPGEnc比?
稍微有玩点视频的都知道TMPGEnc是多老牌的软件

只为你存在

鉴定了我入下一代nv显卡的信心。

gromit

tmpgenc是个好东西,经常用到.不知道以后会不会有破解版

惧内也是种美德

TMPGEnc我从2001年就开始用

littlemouse

小日本也支持了？这个强。

惧内也是种美德

下一个应该就是Edius和ProCoder了

Prescott

{lol:]{lol:]{lol:]{lol:]期待CD420 + GTX280 vs. Q9450+GMA3000。

支持NVIDIA，除了性能之外，很多实用的功能和特性也是非常重要的，况且NV在性能上自然也不弱。
