I recently shot about 60 minutes worth of footage on my (American- NTSC) miniDV digital camcorder. Footage looks great– except that everything shot under fluorescent lighting flickers! The reason is that all fluorescents flicker at the frequency they’re beign driven by. In America, it’s 60Hz, which, given a standard shutter speed of 1/125, meshes quite nicely. Here, it’s 50Hz, which clashes really badly. The solution? Use a 1/100 shutter speed. The only problem is that requires going to manual mode– I have to see if there’s a way to permanently set it on my PV-DV402 camera.
