Knowledge
- The importance and methods of retaining the quality of the source material.
- The general VFX shot pipeline, including general knowledge of all artists roles within the shot’s lifetime.
- The film and/or TV shot pipeline, from pre-production, through shoot, editorial, VFX to grading.
- The VFX production pipeline, including shot bidding, turn-over, briefing, reviews, client reviews, deliveries and final delivery
- VFX terminology
- How digital images are encoded and stored, especially colour spaces and their appropriate use
- The differences in linear light, gamma encoded and logarithmic encoded pixel values
- The implications of working with high and low dynamic range images
- The VFX colour pipeline, from acquisition to working space, balance grades, look grades and delivery
- The maths involved with common compositing operations (for example Colour Corrections, Layering and Matte Operations)
- The differences between 10,12,16 bit integer pixel values and 16,32 bit floating point pixel values
- The meaning and implication of pre-multiplication and it’s use
- The makeup of an image, in terms of channels and pixel values
- How composites are created in either layer or node based systems, the created logic is referred to as workflows or scripts
- The importance of building efficient and flexible shot workflows
- The importance of naming conventions and version control
- How readability of shot workflows is important in a team environment
- The impact of accurate bidding/time estimating of shots and the implications to other team members of delivering to the allocated timescale
- How to determine which technique is the correct method to generate the matte
- Motion blur, how it affects the matte and the principals of animation to effectively replicate in the generated matte
- How to analyse the shot to determine the most efficient breakdown of shapes and keyframes
- How to produce a consistent matte edge and to reduce unwanted artefacts such as stray shapes or inconsistent motion along the matte edge
- How the matte will be used in the composite
- How to determine the most appropriate method for removing unwanted artefacts in live action footage
- Camera moves and how they impact patching or frame-by-frame painting
- The process of following image features across a series of frames in order to record the position of an object in the source footage
- Camera moves, how they impact the tracking process and how to select the most appropriate method to produce an accurate track
- The technical process of tracking and how you can improve the accuracy and efficiency of tracking the shot
- Lens distortion and how to model the amount of distortion in live action footage
- Image manipulation
- The effect of filtering in transformations and how to reduce image degradation
- Colour correction operations and their correct use
- Retiming techniques and the technical process underlying the tools
- 3D Fundamentals
- 3D space, including projections and UV texturing
- How ‘match-moving’ is used to track the movement of a camera through the shot footage
- How Computer Generated Imagery can be rendered in multiply passes in order to be adjusted more efficiently in the composite. These passes can include: colour, diffuse, specular, shadow and beauty lighting
- The concept and purpose of a template or hero script
- Perspective, depth of field and scale and how this relates to a seamless composite
- Photographic composition, light and colour
- Team working and division of work
- The importance of accurate briefs and feedback notes
- The importance of timely delivery of briefs and feedback, to increase efficiency within the team
Skills
- Select and use appropriate software tools and techniques
- Use appropriate techniques to reduce degradation of the source material. The quality of the filmed footage should always be retained.
- Use appropriate VFX terminology

- Convert between common colour spaces
- Select the appropriate colour space for the given task
- Combine images from multiple colour spaces
- Apply colour adjustments at the correct stage of the composite, using non-destructive adjustments where possible
- Reproduce simple compositing operations with equivalent maths expressions
- Select and use the appropriate pixel bit depth format for the task
- Correctly use (un)pre-multiplication for colour correction or transformation operations.
- Demonstrate how to build efficient workflows and identify how to improve efficiency in existing workflows
- ·Build workflows with flexibility in mind, to be able to quickly respond to changes to the brief
- Use labels, colour and thumbnails to effectively document workflows to enable sharing of workflows amongst the team
- Accurately bid/estimate how long tasks will take
- Complete tasks within the time allocated
- Generate mattes by roto-scoping and luminance, difference and colour keying
- Produce accurate roto-scope by correctly placing shapes, control points and keyframes
- Accurately replicate motion blur within the roto-scope generated matte
- Use point and planar tracking to increase roto-scope efficiency
- Combine several matte generation techniques to produce a consistent matte for the shot
- Produce a range of mattes for various uses - garbage, articulate roto- scope, soft and hard keys
- Use patching techniques to remove unwanted objects within the live action footage
- Use frame-by-frame painting to remove unwanted objects within the live action footage
- Demonstrate consistency of paint strokes across all frames to ensure a smooth result
- Accurately remove wires, rigs, tracking markers and camera/lighting equipment
- Use appropriate techniques to remove dust and scratches from live action footage
- Create accurate point tracks
- Create accurate planar tracks
