its very need to point at a tv and change the fps if you go higher then standard fps the scan lines race to the right then as u go lower frame rates it races to the left, and the scan lines stop at 30, 20, 15, 12, crud, i forgot the other numbers, i think 5 or 6 oh well, u get the idea, and changing shutter with exposure override to check the correct shutter speeds to watch the lines be thicker and thinner, 1/29 and 1/57 seem to be the correct values which would be 1/30 and 1/60 shutter speed on my sony vx2000 video cam. I am going to tweak my numbers to remind me of the correct ones so i dont forget on the spot. 1/29 and 4 is what i will use for lightning when i get a good day storm to test it on, 4 fps almost wipes out the scan lines altogether from all the frames being on top of eachother and thats a good thing for lightning. Of coarse tripod only, will be fun to test it out, wish i had fireworks just to mess around with 8]
