Explore the World of VFX and Compositing

Introduction to VFX and Compositing

• Visual Effects (VFX) involve the integration of live action footage and generated imagery that would be dangerous, expensive, impractical, time-consuming or impossible to capture on film.

• VFX are used to add impressive content, create an imaginary environment, and add special effects to a movie.

• Common VFX software includes Adobe After Effects, Autodesk Maya, and Nuke, while open source options include Blender and Natron.

• VFX differs from 3D Animation in that it relies heavily on capturing real-world footage and integrating CG elements into them seamlessly.

• Special Effects (SFX) encompass elements like pyrotechnics, fake rain, or prosthetic makeup, while VFX requires a computer for implementation.

• VFX types include Computer-generated imagery (CGI), Compositing and Green screen VFX, and Motion capture visual effects.

• Key VFX roles include Compositor, Concept Artist, FX TD, Layout Artist, Groom TD, Lighting TD, Look Development Artist, and Rigging TD.

• Compositors are responsible for assembling the final shot by combining final layers/renders from other departments.

• FX TDs create simulations of elements like water, fire explosions, smoke, and dust particles.

• Groom TDs create believable hair, fur, and feather grooms for characters, props, and environments.

• Lighting TDs replicate the lighting on set so that the CGI integrates seamlessly.

• Compositing is the process through which two or more images combine to make the appearance of a single picture, and there are different compositing techniques such as Rotoscope animation, Chroma keying, Double Exposure, and Bullet time.Introduction to Merge Operations in Compositing and Career Options in VFX

• Merge operations are used in compositing to combine two or more images or video clips.

• The average merge operation calculates the average of two images, resulting in a darker image.

• The copy merge operation only shows one of the images, in this case image A.

• The difference merge operation shows the difference between two similar images and can be used for difference keying.

• The from merge operation subtracts image A from image B.

• The in merge operation only shows the areas of image A that overlap with the alpha of image B.

• The mask merge operation only shows the areas of image B that overlap with the alpha of image A.

• The max merge operation takes the maximum values of both images.

• The min merge operation takes the minimum values of both images.

• The color-burn merge operation darkens image A towards image B.

• The xor merge operation shows both images where they do not overlap.

• VFX artists can work in TV channels, production houses, VFX studios, gaming industry, media and advertising, or as freelancers.

• The average salary for VFX artists in the USA is $87,750 per year, starting at $68,250 per year for freshers and up to $126,250 per year for experienced artists.
