A vertical short removes the setup sentence that established a pronoun's referent, while the retained caption still begins with the unexplained pronoun.

Root Cause / Diagnostic:
Aggressive short-form jump-cutting often removes context-setting preamble sentences to tighten the hook, isolating downstream sentences that begin with ambiguous pronouns ('he', 'it', 'they'). Retaining the literal transcript caption creates cognitive confusion, as viewers reading frame one have no reference point for the entity being discussed.

Actionable Fix:
1. Edit the opening subtitle text card to explicitly replace ambiguous pronouns with the specific proper noun or descriptive subject (e.g., replace 'He said' with 'MrBeast said').
2. Re-cut the opening frame to include a 1-second visual badge or text title that establishes the subject before the dialogue line begins.
3. Conduct a cold viewer comprehension test: verify that a viewer reading solely the first caption card can immediately identify who or what the video is about.

Pro Tip:
When pruning preambles, rewrite the opening caption as a standalone premise hook, even if the spoken audio uses a pronoun.
