(I have been using shotcut for a bit but i’m new to the forums so hello all)
Im aware that a RGB shift filter already exists but that applies RGB shift to the entire video. Chromatic aberration applies a bit of shift just in the corners, like how a cheap lens would do.
In the image above you can see that the centre of the image is clear but it gradually has more shift as it goes outwards to the edges. could this be done?
Is this the look you going for?
Also added some lens distortion and blur on the edges (visible on the RHS of the train) as many cheap lenses not only introduce CA, but also other optical distortions, especially around the edges.
