1/100th always looks a bit 'shuttered' to me though. It's effectively a 180degree shutter - so gives 50i a 'film look' at twice the frame rate. (I have seen it used very effectively though - particularly on music)
I'd argue it could be a good look for drama... if producers were actually prepared to try and make some that way anyway.
It might go some way to mitigating the supposed "cheap" look (which is all just in our heads anyway), but it might go the other way - mobile video, which is becoming more watched, tends to have the high-speed shutter look, probably for hardware performance reasons.
I doubt it - the smooth motion you get with 50Hz capture is the issue for most. Though at least if you shot 1080p50 you could say 'it was shot progressive'... (And some might not notice...)
I'm not sure what you mean about mobile video - unless you mean video shot on mobiles?
Mucking about with a bit of
makes me think they use about a 270 degree shutter equivalent.
EastEnders is shot on HSC300s and PDW700s I think - both of which are standard Sony 2/3" cameras (the HSC300 can't shoot 25p - so EE won't be going 25p any time soon) I doubt they put any additional shutter in - so I'd expect them to be running close to 360 degree shutter (i.e. 1/50th second exposure for every frame that produces individual fields) That is effectively how tubed cameras worked (though I guess vertical blanking reduced the exposure period a small amount), and I guess standard CCD broadcast cameras emulate that to a degree (albeit without the tube equivalent of rolling shutter)
