Just about anything that can be isolated can be fixed, but I can’t think of a way to fix something as complex as chromatic aberration. Still, you never know: Can you post a screen grab here of what you are trying to fix? I know the folks here love a good challenge.
It’s a simple chromatic aberration. The solution in photography is very simple and available in almost any picture editing software, I just wonder why both After Effects and Vegas don’t have something for that… btw this is a typical CA problem https://www.tlc-systems.com/pp011185crp.jpg
My background is technical, so the extent of my knowledge on chromatic aberration is limited to optics, but if photo editing apps can fix it, the Premiere/After Effects should be able to fix it, since many/most/all? Photoshop filters are available in those apps as well. Can the example image you posted be corrected in Photoshop?
The best results I got for removing the chromatic abberation in this example footage using Vegas is to take the information of the red channel of the footage to create new Red, Green and Blue channels (see figure). (Please note that the result is this way looks much better then when the Green or the Blue channels were used. Also applying the Black and White FX is not giving satisfating results).
