Adusting the exposure when video recording on the Panasonic G7 camera

On the mode dial on top, put it in S mode, which is shutter priority. Make sure your shutter is at 1/60. Panning from dark to light will change the aperture automatically. Keep in mind, the camera thinks you're in photo mode, and displays the 4x3 photo aspect ratio. When you press the video record button, the format changes to the video aspect ratio. If you're in 4k, it will crop in significantly.

I don't think the G7 has auto ISO, (if it does, I haven't found it) but the auto aperture accomplishes the same thing. You might want to check your ISO to see if it's high enough for the dark part of the scene.

Or, if you always want to shoot video in S mode, you can go into the menu (while in creative video mode on the mode dial) and set exposure to S mode. I've never done this, since I always use manual settings, but I'm pretty sure it would work. The problem would be if you wanted to switch to all manual settings in the middle of a shoot (compensating for backlighting, for example) - you'd either have to dive back into the menu, or use the mode dial set on M and then deal with the 4X3 aspect ratio until you start filming.

You can also change aperture while filming in creative video mode with whichever top dial is assigned to aperture, but it wouldn't be smooth, it would change in steps.

Hi uncle dunc.

Thanks for your feedback.

I'm not certain if the camera varies the shutter speed that much or maybe it has a set default speed or about 1/50 sec. So there may not be that much advantage of uing the S mode on the camera. 
What I'm trying to do is to get some practice in recording video using the manual mode. Maybe this mode is not so great for panning into dark scenes where there are big changes of light. The manual mode could be good for recording entertainment on a stage as the exposure should be the same in most cases.
