That doesn’t work, only if checkbox ‘continuously rasterize’ is unchecked, I get a 25 fps camera zoom.
I think I try manually setting keyframes for hold frame every 7 frames, while keeping the cartoon 25fps.
After reading your post I added the posterize time effect on the cartoon layer.
While this effect preserved the 7fps of the cartoon comp over the top composition 25fps(thanks for that), the cartoon composition is showing only 7 fps while zooming in. I want 25fps camera movement over a 7 fps cartoon.
