I had something like that with a workaround that took a JPEG from the camera. Once I pasted that JPEG back in the scene, (like a still, but then saved as a jpeg) there was a difference in color and intensity, so had to adjust it with image controls like saturation an intensity. I think it got everything the way the original video footage color scheme and the grabbed JPEG (or still) color scheme. In your case it looks very off compared to the original footage. Did you change camera? Is the camera interlaced or progressive?
