The footage below is the technical test of heart image. In the shooting process, for tracking points easily, I attach two pieces of paper to Kelly's cloth. And use two masks to cover the papers in post-production process. After That I put the heart image layer on the top of this footage.
After making this VFX, I found that the track point is very important. It will make the heart image follow the people fluently. And the colour of the point should better be green screen colour, because the colour of paper is similar to the sky. So if I use colour key, the sky would also be key out. Therefore, in the final shooting, I would use the green point.
What is more, the best way of tracking point is mocha plugin. It is more accurate than motion track.
good test. I think with this framing the 'heart image' needs to be smaller though.
