Encoding videos has always been time consuming task. Time consumption has been so long because of the CPU’s inability to use its raw power for image processing, which has always been below par when compared to GPU. Traditionally the encoding was done by the CPU with playback assist from DirectX. But with the introduction of Nvidia’s CUDA and Ati’s Stream  parallel processing power video encoding wont be the lazy bit of task anymore. GPU video encoding not only reduces the load on the CPU but also reduces the time for encoding, since GPU is more powerful than the CPU for image processing. Reducing the CPU load makes it possible to all possible things along with the encoding processes which were unimaginable otherwise.

Even though transcoding Blu-ray movies isn’t exactly at the top of everyone’s list, but one can significantly reduce its size using H.264/x264. x264 is the new DivX and its usefulness extends far beyond just ripping HD movies. Its use isn’t going to increase unless encoding using the codec gets faster. Elemental Technologies has been working on a technology they called RapiHD, which is a GPU-accelerated H.264 video encoder. This is introduced in Nvidia’s CUDA.

Many Software’s are already in market capable of using this raw GPU power.

Some of them are

1)Badaboom: Badaboom is a blazingly fast media converter that formats video files for a variety of devices, including iPod, PSP, Blackberry, and YouTube, by using your system’s graphics processing unit (GPU). In a practice that used to take several hours, Badaboom converts feature-length movies in a matter of minutes while keeping the videos looking crisp and clear. By harnessing the power of NVIDIA CUDA-enabled GPUs, Badaboom offloads the CPU to allow users to continue browsing the Internet or checking email without decreased system performance, making transcoding high-quality video fast, easy, and painless.

2)ATI Avivo Video Converter: ATI Avivo Video Converter supports transcoding between H.264, VC-1, WMV9, WMV9 PMC, MPEG-2, MPEG-4, DivX video formats, as well as formats used in iPod and PSP. Earlier versions of this software uses only the CPU for transcoding, but have been locked for exclusive use with the ATI X1000 series of GPUs. Software modifications have made it possible to use version 1.12 of converter on a wider range of graphics adapters. The ATI Avivo Video Converter with GPU transcoding acceleration is now also available for use with HD 4800 and HD 4600 series graphics cards and is included with the Catalyst 8.12 drivers. Support for Vista x64 is available via a separate download starting with Catalyst 9.6. The new software is faster than Badaboom, an encoder that uses NVIDIA’s CUDA to accelerate encoding, but has a higher CPU utilization than Badaboom.Have a look at it here.

3)CyberLink MediaShow Espresso: MediaShow Espresso’s support for NVIDIA® CUDA™ and ATI ® Stream™ technology delivers huge gains when transcoding high-definition video content. Delivering up to 10X FASTER performance, MediaShow Espresso leverages the power of the GPU to the maximum and produces faster results. With faster speeds for HD video transcoding, you’ll spend less time converting home videos to H.264, and more time enjoying your movie masterpieces. MediaShow Espresso allows the output of H.264 content for playback on PSP, iPod, iPhone and PS3 and a choice of video profiles for high quality or small file sizes.Have a look at it here.
