Lesson: The Interactive Media Proofing Engine


Colateral supports dynamic digital assets including:

  • Looping GIFs
  • High-definition video files (MP4)
  • Standalone audio tracks (MP3).  


The interactive proofing viewer adapts directly to the specific media type uploaded:

  • GIF Briefs: The viewer renders live image loops, enabling you to inspect frame rates and catch graphic clipping directly within the workflow layout.


  • Video Briefs (MP4): The viewer deploys custom scrubbing bars, allowing you to pause, rewind, play back frame-by-frame, and review structural layout parameters seamlessly.


  • Audio Briefs (MP3): The viewer isolates waveform metadata alongside dedicated play/pause media tracks, ensuring radio spots or visual-free assets follow the same strict multi-stage compliance approvals.

    Upload failed, file size must not exceed the 20MB limit for PDF, audio and video files.
