FYI: I'm watching on 60hz North-American gear (TV, DVD/VCR or computer).
Looking at some 1970-80s BBC PAL video -- orig. videographed on 25fps (??) 2" broadcast studio machines, I assume -- I notice NO flicker, even in fast-moving scenes. It looks like smooth 30fps NTSC from the same time period.
Some of these programs are classic BBC Dr. Who episodes which switch between video tape and film sources (sometimes scene to scene). And the flicker diff. between the film and videotape segments is very apparent.
I have NEVER watched PAL programs on PAL equipment. So I don't know, e.g., what viewers in the UK would see on their native gear.
Bottom line: why is orig. PAL-shot video as smooth as 30fps NTSC? Is it careful interpolation (conversion) during transfer (e.g. for use in N. America or Japan)? I see NO conversion/transfer artifacts. Might some "PAL" captures/recordings --regardless of where captured, such as in PAL countries -- been ORIGINALLY captured at higher fps like 30 and then converted to PAL for PAL broadcasts and not converted for NTSC. IOW, was the BBC actually capturing/recording at 30fps?
