Running scene recognition on a full-length movie (so I can cut out the ads) is a tedious process. My machine specs include
Pentium Dual Core E5200 Intel G33/31 chipset
2GB RAM
XP Home SP3
and the recognition process can use 95%+ of CPU available. Yet it can still take four or five times the duration of the movie itself to complete scene recognition.
Would installing a Graphics Card help?
