Treat word count as an early estimate
Dividing words by an assumed speaking rate gives a rough planning duration. It does not account for unfamiliar names, numbers, deliberate pauses or time to inspect a diagram. Use a rate that resembles the intended delivery, and label it as an assumption. Do not select a fast synthetic voice merely to fit a plan limit if that makes the explanation difficult for its intended audience to follow.
Budget the time when nothing is spoken
A viewer may need several seconds to locate a highlighted control or compare two labels. Those seconds still occupy the finished video even when no narration plays. Mark pauses in the scene map and test them with the actual visual. Removing all silence can make an instructional clip feel efficient to its editor but unusable to someone encountering the task for the first time.
Read difficult passages aloud
Say the script yourself before generating it. Expand ambiguous abbreviations, decide how a version number should be spoken and rewrite nested clauses. This is not a promise that a particular synthetic voice will pronounce the revised text correctly; it is a way to find writing problems before paying for generation. Keep the precise technical meaning while making the spoken sentence shorter, and let the on-screen material carry supporting detail where appropriate.
A clearly hypothetical calculation
For a fictional 240-word explanation, an assumed 120 words per minute gives two minutes of speech. Three planned five-second observation pauses add fifteen seconds, before any title or closing frame. The example is arithmetic, not an ideal speaking rate or a Fliki quota. If the draft is too long, remove an unnecessary point or split the lesson. Do not silently cut a qualifying condition, accelerate beyond comprehension or claim that a shorter export proves better learning.
