Add subtitles or captions

Add English subtitles to the 10‑minute product explainer recorded April 26, using the spoken script and matching timestamps, then burn the captions into the video file for social previews and produce a separate .srt file. Deliver both by Thursday for the social team.

Before I finalize subtitles for the product explainer, make them approval‑friendly: surface any lines longer than two seconds, flag jargon that needs simplification for a general audience, mark speaker changes, and suggest three shorter phrasing alternatives for any sentence over 12 words.

I imported the transcription for the April 26 product explainer and in the preview several subtitle blocks lag the audio by about 300–600ms. The social lead, Marco, will reject anything that feels off. What’s the likely reason for the offset, how do I fix it quickly for a clean burned‑in file, and what should I tell Marco about the change window we need if there’s a bigger timing problem?

Across projects we waste time fixing subtitle timing, phrasing, and readability after first drafts. Reviewers blame me for not anticipating mobile reading speed and our reviewers want simplified language. What one workflow habit change and two quick quality checks will stop repeated subtitle rework on future videos?
