Unit 203 – Video Software

Aims: This unit is about the ability to use a software application designed to record and edit video sequences.

An intermediate user can select and use a wide range of intermediate video software tools and techniques to record and edit video sequences that are at times non-routine or unfamiliar.

Video software tools and techniques will be defined as ‘intermediate’ because:

  • the software tools and functions involved will at times be non-routine or unfamiliar;
  • the choice and use of input, manipulation, and output techniques will need to take account of a number of factors or elements and at times be multi-step;
  • the user will take some responsibility for inputting, manipulating, and outputting the information.

Examples of context: Recording pre-planned video footage, downloading the footage to a computer, then editing to create a short sequence, including adding some background music or adding them to a file of another application word processing, spreadsheet, presentation, etc.

Learning outcome:

  1. Use video hardware and software to capture sequences

Guidance

The following guidance is not a prescriptive list of activities; they are suggested areas that a learner could show competence in to achieve this
unit. Centres may use some or all of these activities or some of their own devising to teach and help learners complete this unit successfully.

Learning outcome

1. Use video hardware and software to capture sequences

The learner should be able to and understand:

Video compatibility issues:

  • Between built-in codec used by input device, available editing software, file formats

Input devices:

  • Webcam, video camera, mobile phone
  • Difference between analogue and digital
  • Low and high resolution
  • Input techniques:
    • Copy and paste, screen grabs/shots, file download (eg connect USB lead, drag and drop)

File size:

  • Small, medium, large
  • Link between size and quality (eg small low resolution; large high resolution)

File format:

  • Proprietary formats supported by software used (eg QuickTime, RealPlayer, iTunes)
  • Container formats:
    • Audio (eg WAV, XMF, AIFF); Audio/video (eg 3GP, AVI, MP4, OGG, MOV)


Information coding and compression:

  • Codec, compression, difference between lossy and lossless compression
  • Video quality

Store and retrieve:

  • Files (eg create, name, open, save, save as, print, close, find, share) , file size
  • Version control
  • Import data, export data
  • Folders (eg create, name)

 2. Use video software tools and techniques to combine and edit sequences

Sequences:

  • Short (eg 2 mins), b&w, medium-length (eg 10 mins, 30 mins), colour

Marking-up and editing tools:

  • Preset by software, keyframes
  • Sequences: cut, copy, paste, sequence

Combine information:

  • Combine images with sound (eg dub or overlay soundtrack onto film sequence)

Techniques:

  • Copy and paste, insert, screen grabs/shots, file download (eg connect USB lead, drag and drop), file transfer protocol (FTP)

Forms of information:

  • Forms of information:
    • moving images
    • sound: pre-recorded, live, web-streaming

Copyright constraints:

  • Effect of copyright law (eg images)
  • Acknowledgment of sources, avoiding plagiarism, permissions

3. Play and present video sequences

The learner should be able to and understand:

Features and constraints:

  • Software supported, memory, processing speed, screen resolution, data bandwidth, transmission speeds


Display device:

  • PC, laptop, video camera, mobile phone, handheld video device (eg mp3 player, iPod)

Audio/Video quality issues:

  • High or low contrast, volume, visual (eg jerkiness, dropping frames, break-up, freezes, blurriness, pixilation), sound (eg clicks, disjoint, noise)

Adjust playback and display settings:

  • Playback controls (eg start, stop, fast forward, rewind, pause)
  • Sound (eg volume, balance)
  • Screen size (eg thumbnail, quarter screen, full screen)
  • Visual (eg contrast, brightness, colour/b&w)
