I have opened my after effects and there have been all these changes. I don't know where they come from and I can't get back to the normal after effects.
When I open the colour palette the colours show up like in my attachment 01.
When I do blur it reacts really weird like in attachment 02.
And when I export, the video is super overexposed, attachment 03.
I'm not sure if I'm going to be able to use this in the future, but I'm sure I'll be able to.
