Yeah, there is no mechanical device in the video camera that operates like the still’s camera shutter, but there is an electronic equivalent. The shutter speed on the digital video camera is actually amount of time that the sensor is allowed to build up a charge.
The charge is what is used to convert the light to an electrical signal.
Typically the shutter speed will be the frame rate with options to adjust the speed by small increments to counter TV flicker – when a TV is in the shot.
On my camera there are other options like 1/60 and 1/250.

These articles are a good idea. Nice one. I am an amateur photographer so the concepts are familiar to me. Some cameras, or lenses, allow f-stop changes in thirds as well (1/3). Surely shutter speeds don’t apply to video cameras, since the shutter would be open all the time from the moment the video camera is powered up. It’s interesting to compare the two similar technologies.
