Hello, I'm looking for a command line program that will take in a video file and put out the same file with a certain modification. The modification I'm interested in has to do with brightness. Essentially, I want to normalize the brightness over the length of the movie. Even if the brightness goes up and down, I would like to find a consistent level, say the average, and enforce that level over the entire video.
I am recording objects which move, and as they move they reflect light in different ways. Sometimes the orientation of the object causes extra light to be reflected towards the camera. At other times the object dampens the incoming light, and the picture becomes darker. The change in brightness makes the video look unprofessional. I want to mitigate this effect. I can guess how I might go about this if I were forced to write the application on my own, but it sounds like something someone would've already done, and I always like to reuse a good solution whenever I can. Any help is appreciated. Thank you, Kevin Lawler
