Technical Journal ( compositing part - 01 )

Yes, one more step to go. I am doing final composite here. There are so many things what I tried to make it look nice. Among them, the most challenging thing to me is removing all the tracking markers from footage. Of course, this is my first time as well.



Firstly I tried with roto tool to roto out all of these markers. However, I doesn't work well because if I roto out all of these markers, my footage will get holes on it and give me a question of how to refill with corrected one. So, here is the another way what I tried. I used clone stamp tool instead of roto out all of these. So, it will allow me to refill whatever parts I want from same footage. And I thought that I did it.




Unfortunately, it's not work either. The problem is my footage got camera movements and whenever the camera move, the positions of clone stamp where I refilled are also moving along with camera. And then, it's quite obvious that these particular parts what I removed out are moving themselves like hell. That gave me another challenge to solve it out. It seemed like troublesome to me before I found out the clone source in stroke options of the clones I did. This is how I solved it. I just simply put a single jpeg image (which was corrected well in photoshop) under my footage layer. And then, I change the clone source to that image instead of placing on footage itself. The result is good enough and all the clone parts are stopped moving around because their source image is only one and stable. Yes, I did it.




But not yet, because it just only work on where the camera is not shaking too much if it shaking too much, the parts where I removed out are still moving themselves although the clone sources are stable on background. Another problem is coming again and I got a way to solve it out again. Generally speaking, I make some trackers to hold the parts what I removed out.


After that copied and paste the positions of trackers to the clone positions. That's is so painful to track every single parts I want to remove out one by one in short amount of time. Finally, I made it happened.
