The choice of video and audio codec can have an impact on the performance of the application. Different codecs have different benefits, and present different challenges to each part of a system. Fundamentally, there are three key parameters - and a system can be optimized for any two, at the expense of the third.
For example, an uncompressed DPX sequence is high quality and has a low decode overhead, but it has a relatively high data rate. A high-quality XAVC clip will have a relatively low data rate, but a higher decode overhead.
System architects must know where the limits are in their systems. For instance, a workstation’s resources may be overwhelmed by playing back multiple streams of ProRes 422HQ 4K 60 fps content long before PowerScale’s maximum throughput has been achieved.
