Good results. However, it does have a flicker to it. Is this a real time transfer? If so, what was the frames per second rate?

The flicker speed would be indicative of a 3-blade shutter projector running at 18 fps.

Yes. I just wondered if Amund was aware of this. If a variable speed projector is used, he can increase the speed to 20 FPS to eliminate the flicker.

In Europe, we reduce the speed to 16.67 fps.

Well Europe was 625/50 PAL and USA 525/60 NTSC, Britain is now 50 FPS digital so not really PAL as no subcarrier.

The BBC did do test colour transmissions in the 1950's - they were 405/50 NTSC!!!!!

Perhaps a 5 bladed shutter at 24fps would eliminate the flicker.

No, that will only work where mains is 60hZ. But if the shutter is two-blade, 25 fps will be OK.
