Working out NDs advise please.

Just received my NDs and have been playing with them trying to balance settings for video.
Here it is a cloudy, 'brightish' day, frame rate set to 25fps, ISO 100 and shutter speed 50 to balance the frame rate. In order to get a near correct exposure I need to use an ND8!
What on earth willI I do on a bright sunny day to keep theses balanced settings? The P3S has limited settings and as far I can see. I know I can go to a max of 50 fps in a different video size but that is less than desirable for quality.
Video size is 1920x1080.

Maybe your sunny day has equal brightness to today's clouds? ND8 requirement is not at all surprising for 1/50.

My last ND filter used was the ND-64. But I live in the desert and the sun and dirt get bright. Probably same for snow shooting too.

Thanks GMacjq I was only looking on UK sites. GB seems devoid of outlets for these.
