Hey:
We shot some interior footage where I need to blur the background so that my actors stand out. These are medium shots photographed using a combination of BMCC 2.5K RAW and 4K prores. How do I grade the footage so that the background is blurred (out of focus)?
Final Cut Pro X, OS X Mavericks (10.9.2)
Your task will be extremely difficult to the point where it will not be worthwhile.
You would need to somehow select the background by creating a mask and then adding a blur filter.
In Photoshop with a still image this process would not be too hard but with a moving image you would have to create innumerable masks and keyframes.
It could be done but the effort and time involved would be astronomic.
Thank you.
