So I am working on a stop motion and windows movie maker okay until I need to change things like saturation, sharpness and contrast. If anyone knows of a free program that will allow me to edit a saved video file to where I can change those three things that would be fantastic. Thanks.
I feel like if you dig deep enough you'll find a free program, but I'd recommend getting a free trial for some of the programs like premiere or vegas
I recommend scrolling through this topic:
Well, Movie Maker isn't the best option. I would try Adobe Photoshop or After Effects. But they aren't free.
