Tune caption duration when viewers must read more words than the spoken delivery reasonably supports.

Problem

Tune caption duration when viewers must read more words than the spoken delivery reasonably supports.

Solution

Root Cause / Diagnostic:
Crowding multi-word sentences into brief on-screen windows forces viewers to read at an unnatural, stressful speed. When captions flash and disappear before being read, viewers experience visual frustration and swipe away.

Actionable Step-by-Step Fix:
1. Limit Word Count per Screen: Restrict each subtitle card to 2 to 4 words at a time so comprehension occurs in a single cognitive glance.
2. Calculate Minimum Screen Time: Ensure every caption display remains visible for at least 0.3 to 0.5 seconds, matching natural reading cadence.
3. Simplify Spoken Phrasing: Edit voiceover scripts to be concise, eliminating filler words so captions require fewer syllables and characters per beat.

Pro Creator Tip:
If a viewer has to rush their reading to keep up with your subtitles, they will stop reading altogether—and swipe to a creator who respects their pace.
