Fusion Object Removal Techniques
We take the black art of object removal
and turn it into a well explained, follow along scenario,
so that artists will be able to inject more creativity into
their shot list and stand above the typical lower budget looking
shots found way to often in the industry today.
Learn how to remove unwanted objects, reflections,
stabilize 3D camera movement and much more. We have included
footage shot on Red Camera with Cooke lenses to provide the
ultimate challenges for our training lessons.
Introduction
Start off by taking a look at the raw film footage and its
problematic areas. The overview here is to remove the grey
control box in the centre of the image and its reflection,
one of the train wagons, and add an additional window to the
front building.
Patch Projection – Removing Control
Box
Discover how to integrate the creation of a clean patch to
cover up the control box. Utilize the paint tool to clone
the surrounding areas allowing the ability to conceal the
box, while learning to project the result onto a plane in
3D space. Using 3D tracking data, match and integrate the
patch to the general movement of the shot.
3D Geometry – Stabilizing 3D Footage
Film footage shot with a freely moving camera can be extremely
difficult to work with and stabilize. Everything is shifting;
nothing remains stable and there are very limited constant
factors. Utilizing simple geometry and a projection camera,
learn how to simplify this complex problem and create stabilization
of the 3D footage.
Time Offset – Recovering the Wheel
Parts of the train wheels were covered by the control box,
which was previously removed, creating a problematic issue.
The need to identify a quick solution or method to recover
the wheels is crucial to continue the project. Painting the
wheels in place would be a daunting and tedious task; the
best solution is to copy the wheels from an area where they
are not covered. The wheels now can appear on the patch before
the train arrives and the time offset is the solution.
Roto in 3D – Getting Rid of the
Wagon
Learn in detail how the 3D environment can help with rotoscoping.
The film footage has been stabilized from the previous work
and now being able to exploit that footage, the process of
rotoscoping out the train wagon can be conducted on the stabilized
shot.
Bitmaps & CC – Removing the
Box Reflection
Streamlining the project is crucial and if there is way to
use a simple solution for a complicated task, then do it!
Painting out the reflection of the control box from the moving
train wagons could take uncountable hours. Assuming the removal
will not have to be perfect, the best solution would be to
map out the shape of the reflection and color it to match
the rest of the train, this method proves to be much more
efficient.
Adding Additional Elements
Using the 3D environment can really be a bonus to any project.
Simply lining up images behind one another in 3D space can
create convincing parallax effects. The use of simple 3D geometry
or FBX meshes can be of even more benefit. Receive a quick
overview of how a window with a view into the room could be
achieved by utilizing this technique.
