I am trying to come up with a convenient explanation of GPU acceleration and video editing.
I would like to put out some statements and get comments on them.
The major push for the development of graphic cards is to improve the performance of gaming PCs.
The graphics processing for a video game takes a 3D representation of a simulated world and and renders it into a 2D viewing screen for interactive game play.
The graphics processing for Pr takes compressed HD video data and renders it to smooth reviewable on-screen video for interactive editing.
When the editing is complete the, video processor reads the accumulated edited instructions and HD raw files to produce highly compressed HD video (media) files for DVD production and files to be uploaded for online viewing.
Powerful graphic cards (GPUs) have been developed for the gaming industry.
Video editing application developers are utilizing the computing power of the new GPUs to speed up video editing and media file production.
Without GPU assistance the CPU must do most of the video processing.
When the CPU usage reaches 100% the smooth review becomes choppy and irritating
Choppy review reduces the throughput of the editing session.
With GPU acceleration the GPU does most of the video processing and this allows the CPU to process video faster.
GPU acceleration also speeds up the production of media files.
