VIDEO MODE - meter for specific region of frame and/or EC auto-ISO in M

[jodaboda]

In video mode, in "M", I have a selected shutter speed and aperture.  Then I use auto-ISO to adjust exposure.  All well and good, except the camera almost always chooses too dark of a setting (too low ISO), because the subjects are backlit (and not in the center)

I would like to either:

1.  Have exposure compensation in video mode in "M", or
2.  (preferable) Choose a specific region of the frame (say, "bottom third") for metering video (especially for auto-ISO).

2.  Does spot meter mode work in LV?

thanks for the link.  I'll read the thread, but it looks like it's not for video mode-- unless it happens to work for that too (which would be great).

I assume spot meter works in LV-- but I never use AF so I don't know.  I think spot meter only uses the center AF point, regardless of which is in use (at least, with stock firmware)

LiveView metering only uses the area around the focus box - so just move it.

Yes, live view can meter to the area inside the focus box, but only for stills.  I want that for video.
