Running scene recognition on a movie recorded from TV (file size 3 - 4 GB) starts with recognition of 60-odd scenes a minute and Page File Usage of less than 1.5GB. This steadily blows out to PFU of 3GB+ and 15-20 seconds a scene.
I am using 250GHz Pentium Dual Core E5200 Intel G33/31 chipset - 4GB RAM - XP Home SP3.
Is there some setting which will stop this slow-down?
