Our test file is a 42 minute AVI file.
GPU Assisted Media Conversion
Our second media encoding test takes a 4GB 1920x1080 file and converts it with Arcsoft Media Convertor 7 to iPad format. One run is completed with CPU only encoding, the second and third with ATI Stream /NVIDIA CUDA (GPU assistance).
Using vReveal we are able to enhance low quality video files such as those from mobile phones or digital cameras and reduce the processing time. If a user has any video which is shaky, dark, fuzzy, etc. then vReveal and an NVIDIA GPU can improve each of these aspects and more (for free!).
Our test file is a 640x480 resolution file of approximately 90MB which we run through the 1click-fix filters while increasing the resolution to 720p.
When looking at the Windows Drag and Drop Transfer and vReveal results there are very clear advantages to be seen from using our GPU to assist the CPU. In the case of our media conversion test the results look less impressive but what they don't show is that the CUDA results were achieved with less CPU use. The GTX 560 freed up around 4% (on average) of CPU performance for other tasks while the encoding was taking place.
