  1. A is RAW, B is Video Still.

     

    My reasoning: text in the focus point region has red fringing on image B:

    This is also evident elsewhere in the image.

     

    Since there was a 4:2:2 codec in the video pipeline (Prores LT), I would suggest the chroma sub-sampling could be one of the main culprits for those artefacts.

     

    Sorry if I cheated by zooming in and pixel-peeping the images... I only have an iPhone and an SXGA laptop.

     

    Cool challenge - enjoyed it.
