When using the Nikon D90 video mode you can sometimes observe a stuttering effect as it tries to adjust settings to changing light conditions. This can result in less than adequate clips, as shown below. Observe the stepping up and down of the lighting in the clip.
The video above shows the D90 adjusting to light conditions during filming (AE-L off)
This video shows the Nikon D90 holding it’s settings even with changing conditions during filming (AE-L on)
To prevent the camera hunting you can press the AE-L (hold) button before switching to LiveView (LV) mode.
Use these steps to set your camera for AE-L (hold): Menu > Custom Settings (Pencil Icon) > f (controls) >> Assign AE-L/AF-L Button > AE lock (hold) > OK

A!! was really looking for this. Thank you so much for posting.
Thanks man this works !
big thanks for u !
now, what about the constant strips that go from down to up with Live view on?
Could it be under fluorescent lighting?
good tip. but u dont need to go into the menu, the AE lock button is right there on the back of the camera.
You go into the menu so you don't have to hold the button down, just press it to lock.
Seriously, thanks for this. Now I can stop taping a tiny rock to my AE/AF lock button while I'm filming. Thank you and thank God for Google. 🙂
Go into the menu to set the button to hold, Menu > Custom Settings (Pencil Icon) > f (controls) >> Assign AE-L/AF-L Button > AE lock (hold) > OK
