Motion Capture - tweaks and enhancements.
I have been using SS for 9 months to record traffic and number plates within 6 -60feet of an HD IP camera. I am pushing the limit of the motion capture triggers and wonder if there are enhancements that could be made.
I have set a mask to ensure waving trees don't trigger, and also to mask cars - so I only get bigger vehicles - vans and trucks. I also have set the shutter to a fast speed to freeze fast moving vehicles or those closest the camera.
Here is a still capture with the mask overlayed to show the scope of the trigger. This vehicle was driving fast and triggered late. I could widen the mask a bit but that triples the captures I don't need. https://duaw26jehqd4r.cloudfront.net/items/0b2a2K1t1A1N202x2G07/Screenshot 2019-01-15 at 07.55.50.png
However I am missing some vehicles because the trigger is too late and they have exited frame.
Q1 - Is there a way to pre-trigger capture?
Q2 - Is there a way to decrease the time between captures? Currently Freq:1 Post Cap:1 - Ideally I'd like a 0.5s pre-capture and 0.5s frequency.
Q3 - Lastly I am not convinced the triggers reset quick enough. If I have a line of traffic of 20 vans then the capture is only the first 3 or so and the following 17 are ignored.
Q 4 - Lower priority wish: can different masks or capture pre-sets be applied during different schedules? The setup of triggers when IR is on is very different to normal vision (headlights illuminate areas and false trigger)
