How to change brightness of only some points of the clip [Vegas 13]

Hi, I'm editing a short film and I'm having a trouble. In a scene there is light coming from the window and i need to make it black, because the scene is set at night. I have no idea how to do it. Is there a way to change brightness of selected points, maybe?

Here it is a frame from the scene.

Hi,
if your camera is not moving, you can try masking the window (pan/crop - mask).
If your camera was handheld, you can still try to mask it, but probably you'd need tons of keyframes to be accurate.
In this case I'd even try chroma key, that may work too, if your scene is dark overall, but the window is so bright that it burns. Chroma key set to white (or near white) may mask it out. Experiment with it!

And when you already have masked the window, place something to the track below, which you'd see in the night when you whatch out of that window.

Kind regards

I like László Kovács approach. Here is another one :

Sony Secondary Color Corrector to isolate those highlights. Converted them to a Transparent selection using the Alpha Slider. Then under that Track placed a Solid GenMed and matched its colour to that of the blind thing. Added a very soft Gaussian blur.
