Avengers Infinity War

Thanos is not your usual Marvel slavery. Again, even after 19 films in Disney's superhero universe, it's not that he has a very strong competition. In addition to Loki and Tragic Kilimonagar, most Marvel villains have forgotten a lot. Now, after the years of building (for the first time we caught a glimpse of Thanos in The Avengers of 2012), eventually they took center stage in the avengers of this summer: Infinity War, which is now available on Blu-ray and Digital.

But the most interesting thing about Thanos is not that he wants to erase half life in the universe - instead, it is a big purple alien who feels real feeling. When she is compelled to give up her adoptive daughter Gamora, she cries. She feels pain and pain. But like many memorable bad guys, they believe that it is all good.

The eyes of the intense eye will know that Avengers looks very different in the Thought of Infinity War in a post-credit scene. This is not only due to advanced in CG technology. Kelly Port from the VFX Company Digital Domain said, "We all came to the conclusion that the performance would actually be a little better if we have introduced some recognizable features of Josh Brolin," a firm working on one of the many effects .

Digital Domain also used a piece of custom machine learning software called MaskRad to make motion capture performance even more natural. The process starts by placing 100 to 150 tracking dots on the face of Brolin, which is caught by two vertically oriented HD cameras. It's not about having a high-resolution scan, but it's a fairly low quality rendering. It is fed into a machine learning algorithm which is using high-rage face scan library in different types of expressions.

Port said, "[Maskred] takes that low resolution trap, and it detects that the face of high resolution size will be the best solution for it." So it gives you a solution, and then we will see that result. If this does not look right, then we will make a slight modification in the modeling for adjustment ... assuming that it requires more lip compression or brows, to be high, we feed it back into the system and this machine learning algorithm Will learn through. "

The next time the digital domain keeps a low-res network through its system, it should have a better result than before. But this is just one step. Next up is a process called Straight Drive, which performs high-resolution face masks and keeps it on the character model of Thanos.

Port said, "And then we go through a similar process that we see them on one side." "We look at the performance of Josh and it seems, 'He is even more shocked,' or 'he is more sad here,' and there is something in Josh's performance that is not coming to Thanos that we have a little adjustment We will feed that system back through the system, and then hopefully the next input will be fed directly into the drive system, the result will be more accurate or the more we want. "

Without a machine learning system like Masked, VFX artists have to manually twitch the face with animation, a process that can be time-consuming. Nevertheless, there are other modern techniques, such as Veta's Oscar winner FACETS, which was used for avatars on face tracking and the recent planet of the Apes trilogy.

Marvel Studios' VFX supervisor Dan Delive said, "We knew that Thanos has to go, or the film does not work." From the beginning, his team focused on understanding him as a character. Based on the glimpse of them we have seen before in Marvel films, they knew that he would be a big and angry character - a huge who is literally railing against the universe. But Marvel also wanted to capture Josh Brolin's performance, especially the subtle aspects of his face.

On the first day of the set, director Joe and Anthony Rasos did not waste the brothins in the mole capture helmet and suit to test some of their lines. But they went one step further. Delive said, "When they stopped stopping the lines, we continued the motion capturing." "We kept it when he was just experimenting with different lines and how he would contact Thanos."

By using off-the-cuff lines, Marvel Studios was able to capture the speculations that Deli did not originally plan. "Just being able to read almost unchanging movements in his face ... his movement in his eyes and his cheeks, and then you know later to show his frustration with Gomora, or to show his anger with Tony There is actually such a character on a bring screen, I think that was one of the biggest challenges, "he said.

"Doug Roble, the guy working on that person [digital domain] software said something, 'If you are not using machine learning in your software, then you are doing it wrong,'" Delive recently The said VFX company will visit. Looking forward, technology will be used only for more than faces - this can help in things like water simulation. Finally, when you talk about visual effects, Can not expect to learn.
