  • Strobing

    From Norman Wells@hex@unseen.ac.am to uk.tech.digital-tv on Sun Jun 21 14:41:34 2026

    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.

    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)?
