Applying color correction degrades image

I wanted to add the color filter to the image and this is what happened.
Image is High RES and scaled down.

Hmmm! Added images but they don't show...

Image was nice and sharp.
After adding filter all the borders are pixellated.

When you post an image, 72dpi, no more than 2000 high or tall, there's a limit here. Regular Mac screen shots are too big and too high resolution.

I think what you need to do it go to the Viewer menu, switch from High Performance to High Quality, maybe.

When you apply the Color correction effect, are you adjusting anything first?

Tried the performnce switch but it didn't change anything.
I just reopened Motion.
Now it works...
It seems I have to do this. Quit and restart to make it work.
Thanks for the info on posting images. That will help for future post.
