Change part colour for entire video

Hello,

I have created a video of a building in which I rotate around the building and add (unhide) different components to the building throughout.  Some of the parts are not the correct colour/material and I would like to change their colour for the entire duration of the video.  In other words, I don't want the parts to gradually fade into a new colour, I want them to start and end the same.  Unfortunately, when I try changing the appearance at the beginning or the end of the video, new Keys are created, and this gradual change is what occurs.  If I change the colour outside of the Motion Study, the changes aren't transferred back into the Motion Study.  I've been changing the override colours.

If anyone has any thoughts, I would really appreciate your help.

Thanks so much!
