However, with many big blockbusters, especially action movies or fiction, monumental techniques are also one factor that cannot be ignored. This is the last stage done in every film or television project, takes place for months and plays a decisive role in the “appearance” of the movie.
One of the most commonly used techniques during shooting to facilitate post-production is green backdrops. This is considered a powerful weapon for VFX experts to turn out anything they want with specialized graphics software. The reason why these fonts are blue is because they almost do not match the skin, natural hair and eyes of the actors, making the background separation process in the computer faster and simpler (you have Can learn more in this paragraph).
VFX expert Ian Hubert shared the post-production work of Dynamo Dream, showing everyone just how powerful the green backdrops are.
Recently, VFX producer and producer Ian Hubert posted a series of photos before and after the post-production of some scenes in Dynamo Dream, in order to help the audience to see the terrible power that the green screen possesses. Ian, who has many years of experience in the field of cinema with works such as Project London, Dynamo, Tears of Steel, Ian still regularly shares his knowledge on social networks to help younger people have the opportunity. learning and personal development association.

Even the truck that was rushing on the road was done using a green screen and Blender, the actor was completely safe during the filming of this scene.
On set, there aren’t too many props, but after going through the post-production process, we seem to enter a completely different world.
A small studio room suddenly becomes large and vast, and has depth and class.
External supporters can also be easily removed during post-production.
The green screen helps VFX experts erase the background faster and easily integrate whatever they want into the frame in the most realistic way.
For scenes like elevating up and down, Ian used a technique called Motion Tracking to track the actors’ movements.
In fact, the actor just needs to stand still in one position, the rest has a blue screen and the Blender software.
In the video, we can see the elevator has gone through many different floors, but in reality, there is still only one floor of the studio only.

Therefore, the amount of work for Ian is relatively much when he must build a world as complex, detailed and realistic as possible. In addition to his skills and experience, these blue fonts have helped him do it much easier and faster.
