Did you adjust saturation levels?
Either in the player or in the video editing program...
Red tint is usually caused by over-saturation. 
This is my 1st movie and it’s only 90 sec. When i publish it to anything(email, cd, computer etc...), the audio is great, but the video has a terrible red tint I’ve checked and checked and there aren’t any effects assigned to the video....PLEASE HELP!!!! I’m working on a deadline!!!!!!
