I don't mean like a PiP object, but like an effect you can apply to an image that makes the image brighten and darken, like thunder. Similar to the old movie effect

Well you can do that with a combination of lighting changes and keyframes, or you can try the Old Movie FX:

Yeah I tried using old movie, I don't think there's any way to make the flicker brighter and darker. Like I mean how it flickers stays constant, I want it to grow really bright, then dark, then kind of bright, then dark. I could always hit split and make each image brighter but it doesn't give off a flashing effect, you know? Sorry this sounds extremely unclear, I just really don't know how to explain it lol. I'll give an example of what I preferred it to look like:

Go to this video and to the time stamp 10:01. See how it flashes there?

The easiest way to do what you're looking for is to use keyframes to set the overall brightness at a low level then jump up to a higher brightness for a frame or two and go back down. You'll have to do it several times in random locations to make it look like real lightning. Ther are actually several FX with lightning bolt shapes if that's of any interest.

The windows scene in the linked video is much more complex, because you'd need to have a mask in the shape of the window to only brighten things showing through it, and then to also light up the inside frame on the brightest flashes.

Its actually not so much where the flash is coming from, no need to mask it. What I meant by showing you that is how smooth the flashes look, in comparison to if I adjusted the brightness of the image at random points. It wouldn't look like real lightning flashes. Again, I apologize for how unclear and stupid this sounds lol.

Actually, I think I got it. I'll use old movie and adjust the noise option at random intervals and that might work

I think the Lighting 2 effect would be easier and do exactly what you want. You just need to enable "Thunder Flash" and then set the "Core Size" and "Glow Size" to zero. Doing this gives you a similar flash.

I have used a white color board and either key frame the opacity or split them so short it appears to flash. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)/Nvidia GTX 960(4GB)/16GB DDR3/7,200rpm/w10x64---
