Elements and Performance Criteria Pre-Content


Performance Criteria 

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

4.4 Review completed render to ensure quality and compliance with system requirements and client brief

5. Present composite to client for final approval

5.1 Present final composited images for client approval

5.2 Make adjustments to composited images where required to meet client requirements

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • communication skills to communicate and negotiate effectively with suppliers, colleagues and clients
  • planning and organisational skills to:
  • manage time and resources
  • optimise equipment and resources to achieve desired technical outcomes
  • prepare hardware and software resources for compositing
  • problem-solving skills to solve technical problems associated with compositing
  • safety awareness skills to demonstrate safe and healthy workplace practices
  • technical skills to:
  • composite a range of elements using computer software
  • efficiently render composited scenes
  • interpret client compositing briefs
  • use advanced computer graphics software
  • use compositing techniques to develop and realise client vision.

Required knowledge 

  • 3-D modelling, animation and visual effects development
  • aspect ratios for image output
  • camera, lighting and shadow matching
  • efficient sizes and appropriate formats for composited files
  • game development
  • post-production scheduling and sequencing
  • range of compositing software available

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • adhere to design brief requirements
  • complete compositing tasks to the required level of quality according to the brief
  • use and refine elements for consistency, best image quality and visual impact
  • adhere to system requirements related to file size, format and storage for efficient retrieval
  • apply safe and healthy work methods while undertaking compositing work.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • computer hardware, software, games engines and file storage
  • compositing and output briefs
  • elements to be composited
  • copyright and intellectual property legislation
  • OHS legislation and enterprise policy
  • appropriate learning and assessment support when required
  • modified equipment for people with special needs.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • case studies
  • work samples or simulated workplace activities
  • observation of the learner observing appropriate and safe work practices, and maintaining and organising their work space
  • verbal questioning or interview to confirm knowledge of compositing processes, and methods used to resolve issues and problems
  • informal individual presentations demonstrating progress toward resolving issues arising in a composite
  • written or interactive computer-based test or quiz
  • fault-finding exercises
  • reports and logbooks.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
