I use movie maker to make youtube videos and i use the same camera for my videos but after saving some of my video's color gets altered? Like and orange brown color over the video but this doesn't happen every time. My camera is a sony alpha 5000, I'm using the 2012 version of Movie maker, my laptop is windows 7, acer. It only alters the videos not the text or pictures. My raw video files are all AVCHD Video (.MTS), and then when i save my video for publishing it turns intoWindows Media Audio/Video file (.wmv) or   Video (.mp4). I don't know why some videos have discoloration and some don't, any help is much appreciated! 

Here's one of my videos with the color problem

Then here's another one that doesn't have that problem
