Hi guys.

I have a still scene (meaning only the actor is moving) the camera is stationary... The scene needs to take place at dusk but it was filmed at midday. We left the window in the footage for light with the idea to dim outside where the window is in the corner of the frame (which is too sunny).

Surely there's a way but I cannot find this?

Basically I want to keep the brightness of inside and dim what appears outside?


Please help I've been trying to do this for hours.

You need to use Gamma correction. I don't know which version of PD18/365 you have, but the subscription version should have two FX with that ability (Gamma Correction and New Blue Gamma Corrector).

If you need more assistance, please take a screenshot and attach it here so other people can give it a whirl.

You can also do masking to fix the window brightness problem. Try this: Put the video clip on track 1 and a duplicate on track 2. Use Fix/Enhance/Color Adjustment and lower the exposure appropriate for the window for the clip on track 2. Open mask designer for the clip on track 2 also. Choose a rectangular mask appropriate for the window, uncheck maintain aspect ratio and resize to place it on the window only. You can feather the mask if you want.

You should have a clip with the window darkened. You can readjust the exposure and the mask to get it perfect. I just tried it and it looks good.

I'm not sure how to upload an image on here so I'll link to it. https://imgur.com/a/waeybrL

Basically the window on the right.


Thanks for all your help

How Do I move the gamma correction only over the window?

You don't. Tomasc and I are suggesting two different approaches. If you use GC, it applies to the entire frame which makes it well suited even if things move around. Tomasc's approach is specific to the light from the window, and will work nicely for this clip because the camera and room are stationary
