How to Keep Graphics In Sync When Editing a Voiceover

What to check for graphics and B-roll

B-roll often covers a stretch of picture; a graphic or animation may need to appear when a specific term, number or event is mentioned. The timing precision depends on the video’s purpose, so do not assume every graphic must trigger on a particular word.

For important graphics, record the sentence/section, event and current in-point they relate to. After a voiceover revision, check whether that sentence was removed, moved or rewritten, then reposition the graphic. Review the out-point and duration of adjacent shots if they are affected too.

How can you synchronize slide narration with animations?

Mark the narration sentence or event associated with each slide, then set animation starts/ends. When the narration changes:

1. Compare versions and locate affected slides/sentences.
2. Find the corresponding explanation in the new narration.
3. Adjust animation and transition timing for those slides.
4. Play the surrounding sequence to confirm the animation does not precede the explanation or arrive on the next slide.

A fixed duration per slide can be a starting arrangement, but changes in speaking pace or pauses require another check. Use the editor’s current official help for keyframes, markers and animation controls.

Check whether the voiceover caused a global sync offset

If all audio and picture are offset, check track/clip start points, clips moved independently and the editor’s sync settings. If the offset grows over time, compare the start, middle and end, then check timing according to the device and software guidance. For sync issues, see the multicamera/multirecorder sync guide; for B-roll that no longer matches the narration, see the voiceover-change B-roll guide.

Make later revisions easier to review

• Record the voiceover version or script date.
• Note which sentence, slide or event each key graphic supports.
• After each revision, review affected sections and then play the surrounding context.
• Keep a calibrated version for rollback or comparison.

These steps support a manual review; they do not guarantee that graphics will automatically move with text.
