What is VFX?
VFX (visual effects) is the process of combining computer-generated imagery (CGI) with live-action video footage to create scenes that wouldn’t otherwise be possible or to fix, stylize or adjust footage for creative or corrective purposes.
It’s used in almost every type of film and TV production and involves a combination of creative and technical skill sets, as well as strong attention to detail.
What does a VFX artist do?
First, let’s look at the difference between a specialist and a generalist.
So we know specialists do a lot of the same thing, and generalists do lots of different things. But what do they do?
An animator’s job is to breathe life into the CG elements by dictating the realistic movement of objects, creatures or effects in a scene. In a fantasy film, the wispy movement of a wizard’s spell would be dictated by the animator.
Rotoscoping is the process of tracing the frames in live-action footage. If you wanted to give an actor a robotic arm, the Roto Artist would trace around the arm, frame by frame, to designate where the computer-generated imagery is placed.
Match Mover (Camera Solver)
Match Movement (or Camera Solving as it’s sometimes known) involves extracting the movement of actors, environments or other elements from live-action footage to match it up with CG elements added in post. Say you had a shot with a lot of camera movement, and you wanted to add an explosion to the scene. Camera solving can be used to track the movement of the environment within the frame, so the explosion moves with it and looks at home within the shot.
CGI (Computer Generated Imagery)
Modeling artists are responsible for building the 3D elements that are to be added to a scene. Anything from cars and buildings to fantastic creatures or futuristic weapons.
A ‘shader’ is a texture that can be mapped onto a 3D model to affect the way it looks or how it behaves in certain lighting conditions. The texturing artist’s job is to design and apply shaders to 3D models. Shaders might replicate anything from human skin to cast iron, granite or even tree bark.
Even the most impressive visual effects can fall short if the lighting doesn’t look realistic. The lighting artist uses virtual light sources and their knowledge of how light behaves in different environments to make every computer-generated element look good, and appear right at home in the live action footage.
Environment artists use a combination of image manipulation, 3D modeling and texturing to build environments. They have an important job in delivering the setting, and as a result, the atmosphere of a scene.
Matte Painters build backdrops for use in production. Far-from-home skies or futuristic cityscapes are usually designed by the Matte Painter through the creation and manipulation of images.
Artists in a visual effects department need a visual idea to keep them unified toward a common goal. Concept artists devise the initial concept for the look and feel of a VFX shot, which is then passed further down the pipeline to other VFX artists, who work together to assemble the final product.
Compositing artists have the important job of bringing everything together. We can’t just expect to dump everything into our footage and have it look good. Strong attention to detail and a solid understanding of lighting puts a compositor in the perfect position to seamlessly stitch together all of the elements in a scene.
Technical Directors (TDs)
Technical directors usually specialize in a field like maths, computer science or physics. This allows them to simulate realistic visuals, or to program scripts which aid in the design of effects.
Effects TDs come into play when complicated effects like realistic explosions or avalanches need to be created. An Effects TD will design the arrangement of a number of independent effects to achieve the end result. They might even simulate the laws of physics to create an accurate depiction of what would happen in real life.
A Rigging or Animation TD might be responsible for programming the complex mechanics behind how a CGI dinosaur moves to make it look realistic, and most importantly, alive.
How much does a VFX artist make?
The earning potential for a VFX artist is varied, work ranges from unpaid internships to six-figure salaries. Starting salaries are usually around $19,000 per year, with earning potential increasing with experience. The amount you earn depends on a number of factors like experience, the type of content you’ll be working on, and what your specialism is. The average salary is around $51,000 per year.
