Punjab PSEB Sr. Sec. NSQF Media (Roto Artist) key terms

The sector that produces films, television, animation, games, advertising and audio content. It employs creative, technical and support roles, and in India it is a major source of skilled jobs.

National Skills Qualifications Framework: India's system that grades skills from level 1 to 10 and links training to recognised job roles, so a qualification signals a defined set of workplace competences.

A defined set of duties and responsibilities attached to a specific position, such as Roto Artist or Paint Artist. It lists the skills, knowledge and outcomes expected from the worker.

The creation or alteration of moving images after live-action shooting, adding elements that cannot be filmed practically or removing unwanted ones, usually combined with the original footage in compositing.

The process of combining multiple image layers such as plates, mattes, computer-generated elements and effects into a single seamless final image, matching their colour, light and motion.

The frame-by-frame drawing of shapes around an object in live-action footage to isolate it, creating a matte that allows that area to be extracted, replaced or adjusted later.

A curved path made of control points and tangents that a roto artist adjusts to trace an object's outline. It defines the shape of a matte on each keyframed frame.

A smooth curve defined by anchor points and handles that control its direction and bend. Roto tools use Bezier curves because few points can trace organic edges accurately.

A movable point on a spline that determines where the shape bends or turns. Adding points allows tighter corners; too many points make the shape harder to animate cleanly.

A frame where an artist records a value, such as a shape's position, so the software can interpolate between recorded values on the frames in between.

The way software calculates values between two keyframes, producing either smooth or stepped change. Choosing linear, smooth or hold affects how naturally a roto shape follows movement.

Analysing a sequence to follow the movement of a feature or pattern over time, producing data used to stabilise footage or to attach a shape or element to a moving object.

Using tracked motion data to make a new element, such as a painted patch or graphic, follow the movement of the filmed object so it appears locked to the scene.

Removing unwanted camera shake from footage by tracking motion and shifting each frame, often requiring the frame edges to be filled or reframed afterwards.

A greyscale image where white reveals and black hides, used to control which parts of a layer are visible. Roto artists produce mattes to isolate subjects for compositing.

An extra image channel storing transparency information alongside colour. Values range from fully transparent to fully opaque, letting layers combine without hard visible edges.

A rough shape drawn to exclude unwanted areas such as rigging, crew or set edges from a shot, so the more detailed roto work only needs to cover the important region.

A closed or open spline drawn around a subject in a shot. Artists animate its points across frames so the shape stays aligned with the moving subject.

Removing unwanted elements such as wires, tracking markers, dust or logos by cloning or painting from nearby frames, then matching grain so the repair is invisible.

A painting tool that copies pixels from a chosen source area to another location, letting artists paint out unwanted details while keeping surrounding texture consistent.

The original live-action footage supplied for a shot, before any effects work. It is the reference for framing, lighting, colour and motion throughout the pipeline.

A separate level in a composite holding an image, matte or effect. Layers stack in order, and their blending and opacity determine how they combine into the final picture.

A shape or image that limits where an effect or layer applies. Unlike a matte used for extraction, a mask usually controls visibility of an adjustment within the composite.

A rule for combining a layer's pixels with those beneath it, such as multiply, screen or overlay. It changes brightness, contrast or colour interaction without altering the source images.

The degree to which a layer or brush stroke is opaque rather than see-through, usually expressed as a percentage. Lowering it blends an element gradually into the background.

Adjusting an inserted element's brightness, contrast, saturation and colour balance so it matches the plate's lighting and grade, making the join look natural.

The pixel dimensions of an image, such as 1920 by 1080. Higher resolution holds more detail but increases processing time, storage needs and render load.

The proportional relationship between an image's width and height, for example 16:9 or 2.39:1. It must be preserved when resizing or delivering shots.

The smallest addressable unit of a digital image, holding colour and sometimes transparency values. Images are grids of pixels, and their count defines resolution.

The number of bits used to store each colour channel's value. Higher bit depth records finer tonal steps and reduces banding during colour correction.

A defined range of colours and how they map to numbers, such as sRGB or a logarithmic film space. Working in the wrong space causes shifts in contrast and saturation.

The structure used to store an image or sequence, such as EXR, DPX or QuickTime. Choice affects bit depth, compression, alpha support and compatibility with the pipeline.

Random texture in film or sensor noise in digital footage. Clean-up and inserted elements must have matching grain added, or the repaired area looks unnaturally smooth.

The ordered stages a shot passes through, from brief and plate intake to roto, paint, compositing, review and delivery, with checks and handoffs at each stage.

A continuous run of frames from one camera setup, identified by a code such as scene and shot number. It is the unit of work tracked through the effects pipeline.

The specific files an artist must hand over, defined by naming, format, resolution and frame range. Meeting the delivery specification exactly is part of professional practice.

Practices that prevent injury and illness at work, including safe screen setup, correct lifting, electrical care, fire awareness and reporting hazards before they cause harm.

Arranging the workstation, chair, monitor and input devices to suit the body, reducing strain on eyes, wrists, neck and back during long editing sessions.

The ability to use computers, files, networks and software confidently and safely, including managing folders, backing up work and protecting data and privacy.

Transferable abilities employers expect, such as punctuality, teamwork, clear communication, problem solving and willingness to learn, alongside technical craft skills.

Behaving honestly and responsibly at work: respecting confidentiality of unreleased footage, crediting others' work, meeting deadlines and raising problems early rather than hiding them.
