Smarts vectors are a way of tracking the image that in some cases makes the job a lot easier if it works properly. We are going to use it for a few practice to learn it, we are going to make a person look younger and also remove some tracker markers from someone.
The first practice is going to be beauty work. I will make a person look younger using smart vectors to track the video and after that, I’m going to create a clean plate that with smart vectors is going to move with the video. Here is the node editor:
We first reformat the plate since it was in 4K and for this exercise, I will work in 1080 then I denoised the plate, and after we create the vectors. This is the first time using this feature so here is how it looks. We can see the vectors on the viewport and the attributes that we can change. I left it to default for now.
I’m going to create the patches with a rotopaint node, using cloning and blur tool. I created a grade node, so its easier to see if the track works well.
Here we can see the difference between the original plate on the left and the modified one on the right.
Here you can see the parts the I modified with the rotopaint:
And here we have the original plate:
This is the end result:
UPDATED AND LONGER VERSION
At this point I modified a little bit the patch I made and also created a few more to make the video longer.
An this is the final result with different passes of the process.
