Wimbledon Super Slo Mo Flicker

[Sizzers]

When they're doing super slow mo it just flickers like mad, almost like a strobe. Anyone else suffering this?

This is through both SD and HD, and never experienced this at Wimbledon before or on any other sports. Any ideas?

Yep, same here.

Obviously picked a random (prime) number for the frame rate(!)

lol Well they always give warnings on the news when there's flash photography: they should do the same with this!

I noticed it on Wimbledon last year and its there again this year. Out of interest are your TVs 1080 full HD or 720. Mine's 720 and I was wondering whether the flicker might be caused by the down scaling from 1080.

I always though it was due to the lighting, as I've seen a similar effect in one or two films when strong lighting is used.

Yep, Frank is correct, it is the light source flickering. I used to have these really powerful bike lights for riding in the woods at night, and I tried using them as a video light. Got a very similar effect at certain shutter speeds.

Makes sense - anything above 50fps (half speed) will be faster than the overhead lights turning on and off at 50Hz. Guess we don;t normally notice because Wimbledon's not often under lights!
