I have 320 x 240 mpeg videos of an equipment that I shot at work over a few days. Each video is 12 hours long. The camera and equipment were stationary. I was basically interested in capturing the equipment status indicator lights. The green light would be on when the equipment is running and off (no light) when it stopped.

I have been using Womble MPEG Video Wizard to mark the frames when the light turns on and off. I then use a text editor to extract the frames positions from the project file and analyzed the data in Excel.

I have 5 days worth of videos of 12 hours each to analyze. Though i could playback the video in 16x speed, it is still time consuming.

I have been googling for such filter or plugins but no luck.

I would be very grateful if anyone could point me to the right direction. Perhaps someone could help me with an avisynth script or virtualdub filter?

Thanks in advance.
