Provide Two Corresponding Recordings
Upload the video and the separate audio captured for the same event or performance.
Sync Audio and Video
Align a separate audio recording with the matching video footage. The Pexo AI video agent uses matching content or a supplied cue to set the initial offset and presents the aligned result for drift review.
Matching recordings
Upload the Video and Separate Audio
Add one video and the audio recording that belongs with the same event.
A clap, spoken phrase, or other supplied cue can help identify the intended sync point.
What it is
Align Separate Sound with Its Matching Picture
Sync Audio and Video corrects the starting timing difference between a video recording and a separate audio recording of the same event.
The workflow aligns existing recordings; it does not generate new speech or change visible mouth movement.
Identify the Alignment Cue
Use matching speech, a clap, or another shared moment to establish the intended starting point.
Review Timing across the Video
Check the start and later moments to see whether picture and sound stay together.
How it works
Align Separate Audio in 3 Steps
Provide the corresponding recordings, establish their shared cue, and review both initial offset and later drift.
Upload the Matching Recordings
Add one video and the separate audio track that corresponds to the same action or speech.
Set the Shared Sync Point
The Agent compares matching content or follows the cue you provide to position the audio start.
Check Initial Offset and Drift
Review the beginning and later sections, then request an offset adjustment if the sound moves away from the picture.
Agent decisions
Decisions Behind Audio and Video Alignment
The Agent connects the matching sources while leaving final timing judgment to playback review.
Sync-Reference Matching
Uses matching content or a supplied cue to identify the intended shared moment.
Offset Alignment
Positions the separate audio relative to the video timeline.
Track Positioning
Follows your start and end instructions when the two recordings have different lengths.
Drift Review
Presents the aligned result so you can inspect timing at several points.
Common questions
Sync Audio and Video FAQ
What files should I upload?
Provide one video and one separate audio recording that capture the same event, speech, or performance.
How is the synchronization point chosen?
The Agent can use matching content or a cue you identify, such as a clap or spoken phrase.
What is the difference between initial offset and later drift?
Initial offset is the timing difference at the start; drift is a timing difference that grows later in the recording.
How should I review the synchronized result?
Check a visible or audible cue near the beginning, then inspect later moments to see whether timing still matches.
Is this the same as lip sync?
No. This workflow aligns recordings that already correspond; lip sync changes visible mouth movement to follow audio.

Align Your Separate Audio and Video
Upload both recordings, identify a shared cue, and review timing across the result.
