I've been watching the tennis on BBC 1. When they're bouncing the ball before serving, the ball noticeably strobes yet it's by no means the fastest it's going to move later, when there's no noticeable strobing at all. Why is that? I thought it might be the effect of the hoardings around the court which are electronic, but it's apparent even where the background is the court itself, which of course isn't. So, what's going on please?

I can't see any strobing on Ch1 or 101. -- Jeff

Why is that? It's only on redbutton now at 3/4 of SD resolution, so difficult to tell. Perhaps fast shutter speed on camera(s) facing into the sun and slower shutter on wide shot camera(s)?
