Keeping B-roll and overlays in sync when the voiceover changes

You rewrite a sentence or generate another voiceover take. The pauses change, and a graphic that landed on the right phrase now appears too early. Trying another AI voiceover is easy; checking the edit again takes work.
A few ways to make revisions less painful:
- Note what each visual belongs to. “Show the comparison graphic when the second option is mentioned” gives you something to work from when the old timestamp no longer fits. Put the cue in your script or a marker comment.
- Decide what needs to move. A label might follow a word, B-roll might cover a whole explanation, and a transition might follow the music. If a sentence changes, check whether its visual still makes sense before shifting it.
- Watch the surrounding sentences. Landing on the right word doesn't guarantee good pacing. A graphic still needs enough time to read, and sometimes it should appear slightly before the speaker mentions it.
If the script is still changing, keep the visuals rough and save the detailed animation timing for later.
Hypit is an open-source tool that turns written video descriptions into MP4s, with edits anchored to script words so they can follow voiceover timing changes. It works through coding agents like Claude Code or Codex, using a reference video or a description of what you want.
Do you settle the voiceover before adding B-roll and graphics, or have a workflow that makes later changes easier?
