Video Explainer

Video Explainer — questions and answers

What makes a concept too complicated for a 90-second explainer?

Length constraints work when the goal is communicating one core mechanism or decision framework, not exhaustive coverage. If the idea requires more than three sequential steps, involves multiple interdependent variables, or needs significant prerequisite knowledge, a single short explainer usually oversimplifies to the point of confusion. Multi-part series or longer formats often serve better.

Should the script be written before any visual work begins?

Yes, almost always. The voiceover word count directly determines runtime, and animation is built to match the spoken pacing. Writing script and visuals simultaneously leads to mistimed reveals, redundant on-screen text, or scenes that look good but don't align with narration. Finalising the script first, including recording scratch audio, provides the timing foundation everything else follows.

How does voiceover recording fit into the production sequence?

Professional voiceover usually happens after the script is locked but before final animation. A scratch recording or text-to-speech track is used during storyboarding and animatic stages to establish timing. Once visuals are approved in rough form, the final voice recording is captured, and animation is then timed precisely to match the recorded pacing and natural speech rhythm.

What's the difference between an animatic and a storyboard in this context?

A storyboard is a series of static frames showing key visual moments, often with notes indicating action or transitions. An animatic takes those frames and sequences them in video editing software with voiceover and rough timing, creating a low-fidelity moving preview. The animatic lets everyone experience pacing and narrative flow before committing to finished animation work.

Do explainer videos need to be subtitled or can visuals alone carry the message?

Explainers rely heavily on voiceover narration to convey information, so visuals alone rarely communicate the full message. Subtitles or burned-in captions are increasingly standard for accessibility and for environments where audio plays automatically muted. Many platforms now require or strongly favour captioned content, making text overlays a practical necessity rather than optional enhancement.

Why do some explainer styles use limited colour palettes?

Restricted colour schemes help maintain visual hierarchy and prevent cognitive overload when information density is high. Using two or three brand colours plus neutrals lets important elements stand out through contrast, guides the viewer's eye deliberately, and keeps production efficient by reducing the decisions required per scene. It's a functional choice that also creates stylistic consistency.
