NVIDIA CUDA performance - Video effect rendering with Cyberlink PowerDirector 7 Ultra
Whenever we talk about GPGPU processing in terms of video, you'll probably think of one of two things - Playback or transcoding. While most GPUs now have everything they need to take almost the entire video playback load away from the CPU, even in the case of a 1080p High Definition video feed, we're still yet to see a really great, rock solid video transcoding application that uses the GPU to convert video from one format to another.
However, although unsurprisingly given the focus on creating rather than simply converting video content that PowerDirector 7 holds, the focus of CUDA functionality within this particular application doesn't sit directly with video transcoding. Instead, GPU acceleration is being used within the latest build of this software to accelerate the rendering of certain video effects that ship with the application.
It should probably be noted when I say "certain" effects that CUDA support is indeed limited to just a handful of video effects available to PowerDirector 7 at present, although to be fair these appear to be all of the most intensive effects to process, thus offering the largest potential time savings when it comes to actually producing your finished video and outputting it to a file.
