Use the Lip Sync editor to choose which face is synced in each segment and remove sync where it’s not needed.
Vozo automatically analyzes the video and applies lip sync to the relevant faces. However, after processing, you can customize lip sync in the editor, specifying which face should or shouldn’t be synced during specific time segments.
If your video has multiple faces in a frame, Vozo might sync the wrong face. For instance, Face A and Face B appear, but the audio is from Face B, and Face A was synced.
Steps to Fix:
Pause the video at the segment where both Face A and Face B appear, and the sync is incorrect.
Both faces will be automatically recognized. Face A will be selected by default and show the “Lip synced” status.
Select Face B, which will display the “Not synced” status. Click Set Sync.
Face B will now show “Ready to lip sync”, and Face A will change to “Ready to remove sync”.
Click Update Video after correcting all segments.
If a segment of your video includes voiceover audio not tied to the face on screen, Vozo might mistakenly sync it.
Steps to Fix:
Pause the video at the segment where lip sync was applied incorrectly.
Select the face that was mistakenly synced, and click Remove Sync.
Click Update Video. The face will return to its original state without lip sync.
Sometimes, lip sync causes the mouth to appear over obstructions like microphones or hands in the video.
Steps to Fix:
Identify the segment where the obstruction occurs.
Click the Split button to divide the timeline at this segment.
Select the segment, then click the Remove Sync button next to the face in the preview area.
Click Update Video to finalize the changes.
This approach works best for short, temporary obstructions. If the face is frequently covered throughout the video, it may not be suitable for lip syncing.
During pauses or moments of silence, lip sync may create unnatural facial expressions.
Steps to Fix:
Locate the segment where the face appears unnatural during a pause.
Use the Split button on the timeline to isolate the affected segment.
Select the segment, then click the Remove Sync button next to the face in the preview area.
Click Update Video to apply the changes.
During fade transitions, such as when the screen brightens or darkens, lip sync can make the face look unnatural.
Steps to Fix:
Find the fade transition segment in the timeline.
Click the Split button to separate the transition from the rest of the video.
Select the transition clip, then click the Remove Sync button next to the face in the preview area.
