Some Vegas filters:

1. Original
2. Color corrector (secondary): check the purple (blue) fringing at the porch
3. Same as 2 but reduced blue channel color curve (which looks more like HV20 W/B although now too green for my taste but you can easily change as you prefer).

Steps for removing CA in Sony vegas Pro:
1. Add this filter: Color Corrector (Secondary).
2. Use color picker (select effect range) and choose the area where CA is
3. Turn down the Saturation (2nd from top)
4. Now turn on 'show mask' and play with the ranges until only the area is targeted (saturation/hue/luminance)

PS ignore audio (it's from the HV20).
