    Hi, Whatever it is it doesn't look like a pixel. It looks more like a reflection. Cameras usually have some kind of focus assist light for dark conditions, are you sure it is not that?.

    If you use any digital camera in the dark then you are highly likely to see "hot pixels". They don't flash. They are very small - pixel sized in fact - so they show up clearly if you do a 100% view of the image. The camera usually has an ability to capture a reference dark frame and then subtract this from an image. Whether it can do this with video I don't know - the manual will say - but I think you are asking a lot to work in blackout.

    Also if it is a stuck pixel it is likely to be coloured. White implies at least a group of three, maybe more.

    Is it always there, or does it depend on where you're pointing the camera. It almost looks like an infra-red beam from something else, like a tv, remote control, or similar.

    And sorry if I've misunderstood - when you record the video, and then watch the video back - is it on the recorded video, or is it just on the liveview / LCD while in video mode?

    i.e. is it actually turning up on the resulting video recording?

    Then I have no clue, if it was JUST on the viewfinder, and not the LCD or image then it's not reaching the sensor or is being filtered out before it does.

    But getting to the LCD and viewfinder, but not the sensor (i.e. final recording) is odd.
