The software uses multi core CPU's processing muscle to transcode videos. Support for multi-threading allows MediaShow Espresso to utilize up to 4 processing cores at once.
They also utilize the stream processors in your GPU to convert your videos faster than ever with optimization for hardware acceleration technologies from Intel® Core™ i3, i5, and i7; NVIDIA® CUDA™; and ATI® Stream™.
CyberLink is leveraging ATI's Unified Video Decoder (UVD) in its MediaShow Espresso video converter application. This allows it to quickly convert digital video files for use on portable devices like Apple's iPhone and Sony PSP. CyberLink has also optimized its PowerDirector 7 video editing software to take advantage of ATI Stream.
Tests conducted by ATI showed a reduction in transcoding time of at least 50% in most applications. For example, a 94 second 1920x1080 video encoded at 24 frames per second using H.264 took 131 seconds to transcode to a format suitable for the iPhone using just the CPU. It took just 46 seconds using a mid-range Radeon HD 4670 video card, reducing the time needed by almost 65%. Results would be even more dramatic using a higher end Radeon 4870 or Radeon 4890 GPU. Addition GPUs through CrossFire would provide even greater performance improvements.
So at $40 this might not be High Tech on a Budget but with $1000 dollars or more into a high end system this by comparison not only makes good sense but it is a steal.
