SD780IS - Video exposure compensation and focus

Seems like that's the most common question, so here's a bunch of videos demonstrating how the camera works. Basically, when you start the video the focus is evaluated and then locked. You can use macro/normal/infinity, but it is locked once the video start.

For the exposure there are two modes. The first one is automatic. In this mode the camera will (with a slight lag) change the exposure. If you access the exposure compensation (up on the dial) before you start the video, you will see a

type of dial. You can change down (darker) or up (brighter). The current brightness that was on the screen when you first press the "up" button will be kept in the middle position. I.e. once you take out the compensation dial, the exposure will no longer automatically be adjusted regardless what happens. You can, before starting the video, adjust up or down and see the result on the screen. But once you start the recording, there is nothing you can do to re-adjust it. Unfortunately... I guess this is a point-and-shoot, so maybe it's wrong to expect more? Here are the videos, and remember that the only light in the videos is more or less the three candles:

Auto mode:


Locked - middle setting:


Locked - max setting:

Locked - min setting:


Demonstration of that focus is not updated, start with macro:
