Content Creation and Digital Media Production

What the exam tests

Content Creation and Digital Media Production covers planning, producing, and adapting visual and video assets for social formats: correct dimensions, legible design, accessible captions, and clean exports.

Core rules

  • Aspect ratios: 1:1 square, 4:5 portrait feed, 9:16 vertical for Stories, Reels, TikTok, and Shorts, 16:9 landscape for YouTube and LinkedIn video. Crop and recompose; never stretch.
  • Resolution: design at the platform's recommended pixel size and export at 2x where possible; upscaling a small file produces soft text.
  • Safe zones: keep captions, logos, and calls to action away from edges and bottom UI overlays on vertical video.
  • Formats: JPEG for photos, PNG for graphics needing transparency, MP4/H.264 for video; check each platform's size and length limits.
  • Hooks: the first one to three seconds decide most video retention; lead with motion, a claim, or a question.
  • Accessibility: burned-in or platform captions, alt text on images, high contrast, and a text equivalent for any message embedded in an image.

Worked example

You have a 16:9 explainer and need a Reel. Re-edit to 9:16, move the presenter into the upper two-thirds, place captions mid-screen inside the safe zone, front-load a two-second hook, and export H.264 MP4 at 1080x1920. Reasoning: native vertical keeps the subject large, safe-zone placement prevents UI overlap, and captions serve sound-off viewers, who are the majority in feed.

Traps that cost marks

  • Uploading letterboxed landscape video with black bars.
  • Stretching instead of cropping, which distorts faces.
  • Text hidden behind profile or caption overlays.
  • Skipping captions and alt text.
  • Exporting a low-bitrate file that looks blurry after platform compression.
