Using chroma key assets from Adobe Stock
We have designed a Christmas card and would like to make use of some stock footage to replace the chroma key object and replace with our card. I’m reasonably familiar with keying and motion tracking but I thought that one of these stock assets would be a quick and easy way to do what I need. I can’t for the life of me figure out how to use this. If the green ‘card’ object is static then obviously I can just key it out and replace with my card, but with it in motion and the envelope obscuring part of the box I’m not sure how to proceed. Do I need to create a mask from the box and track my replacement card to that?
Here is the stock video file (once I know how to do do it I will licence the full res version)
Could someone please shed some light, I feel like there’s something really obvious I’m missing.
