Summary: Pavtube products now supports ATI Stream (AMD APP) acceleration technology. GPU-Accelerated encoding with AMD APP (formerly ATI Stream) supplys users Faster video converting/DVD & Blu-ray ripping

AMD APP(Accelerated Parallel Processing) stands alongside Nvidia CUDA as one of the two most prevalent GPU computing platforms available today. Initially known as ATI Stream, the AMD APP is a set of advanced hardware and software technologies that enable AMD graphics processors (GPUs), working in concert with the system’s central processors (CPUs), to accelerate enabled applications beyond traditional graphics and video processing.

How does AMD APP stack up? You might have been impressed with its clear video playback and fast game play and realistic physics effects. But wait, there’s still something you should have a try with- the AMD APP accelerated encoding. Let’s explore how effective AMD Radeon HD graphics are when it comes to video transcoding:

Test 1. AMD Radeon HD6370 (GPU)vs. AMD Dual- Core E2-3200 processor(CPU)



Test 2. AMD Radeon HD 5800 (GPU) vs. Intel(R) Core(TM) i7-2600K (CPU)



Test 3. AMD Radeon HD 5750 (GPU) vs. Asus i7-860 (CPU)



A Summary to GPU Encoding

Overall, we get faster transcoding speed when turning on AMD APP accelerated decoding, and see clear differences between hardware-accelerated decoders. The AMD Radeon HD6370 brings much better result than that with the other two Radeon HD graphics cards. The suggestion here is that you’d see better results if you were stuck on an older machine with a slower processor and modern graphics card (AMD Radeon HD 6000 series and later models).
While working with video clip, we noticed that our files weren’t all the same size. Not only do two different cards not output the same data, but one card isn’t guaranteed to give you the same result from run to run.

Compatibility and Usage

Users will be able to take advantage of AMD Accelerated Parallel Processing (APP) Technology when transcoding video contents on systems equipped with ATI Stream-enabled GPUs. It is also required that you have an AMD APP based video converter software and transcode video streams into H.264 video.

Multiple video encoders are out of there for your choice. The free ATI Video Converter enables basic GPU transcoding of HD video streams. For more advanced transcoding functionality CyberLink’s MediaShow Espresso video converter would be a nice pick. When it comes to transcoding DVD and Blu-ray contents, Pavtube Blu-ray Video Converter Ultimate is the only program that would accept protected Blu-ray movie, DVD as well as HD videos. In other applications, we were prompted with audio codec errors, as none recognizes TrueHD.
