If you film in NTSC in Europe instead of PAL or vice-versa you are screwed.
Companies will never tell you this but there's actually a small logic board in every camera with a chip that detects in which mode you put the camera and then it streams that via 3G to the local feds together with a location based on 3G antenna triangulation.
If the feds find out they will arrest and prosecute you and you have a chance to be locked up and put behind bars for a long time. There is a long history behind this, first America brought out their standardized format 'NTSC' but they were quickly followed by PAL which was imagined by left-wing Europeans backed by the Soviet Union.
It's the last remnant of the cold war, or I'm quite intoxicated.
