White balance?

I’m working on an animation that will integrate 3D models with 2D stop motion animation (weird, I know, but I’m hoping it’ll look cool)

Anyway, either because of the camera, or my faulty lighting control (likely the latter) there is a rather disturbing flicker when the pictures are put together - As shown below




I’m wondering what people would use or try to this situation to balance out the lighting. I’m thinking a white balance would work, but I’m not sure how to batch process this or make Blender do it.

Ideas?

It looks like the camera was set with different modes (you know: sunny, cloudy, fluorescent, incandescent, etc). Either that or the environment changed between shots (lights (windows can be a cause especially if you shoot the whole day long and the shy is partly cloudy), furniture or even your shirt). If you shot with different modes but the environment was controled, then it should be relatively easy to fix that with nodes finding the right balance of red, green and blue channels. If you shot durint the whole day and your environment was poluted by outside light, then you’re in trouble because that will be very hard to fix.

Well, I still don’t know what exactly caused the bad lighting in the first place, but I think I solved it fairly well for this project. So - a simple way to do color correction in Blender!

I loaded my images as a strip in the sequencer and found the Filter options under the sequencer buttons, something I’d never knew existed. And here was a simple 3 way color correcter to use! I kinda ended up overexposing everything, but it looks a sight better than the original flickery stuff.

Note I’m using 2.49 yet…can’t learn 2.5 cause I’m so slow at it and I need to get stuff done!! :spin:

Did you use manual or automatic exposure setting on the camera, that may make the difference although flicker can still occur even with controlled lighting and exposure, but best to work in a dim room, free of indirect lighting influence. There are plugins to help even out the flicker, not for blender though. :slight_smile: same sort of things occur with timelapse shots.

Free methods would be to use something like AVISynth to even brightness and contrast based on a sample frame. never tried that though. :slight_smile:
