List the media and shared references
For each video, camera audio and separate recording, note the filename, source device and approximate start time. Look for a moment captured by more than one file, such as a clap, slate or clear line of dialogue. If usable timecode is available, follow the device and editor’s instructions for that workflow.
If a shared sound is missing from one or more angles, do not assume waveform matching can align every file. Mark those files for separate handling.
Choose a sync method
| Method | When it may apply | Check first |
|---|---|---|
| Waveform matching | The files being compared contain recognizable shared sound | Whether audio overlaps, is clear and covers the needed duration |
| Timecode | The recording devices, files and editor support the relevant timecode workflow | Whether devices were set for it and timecode imports correctly |
| Manual alignment | A shared moment can be located in picture or sound | File count, clarity of sync points and need for later spot checks |
This is a list of method conditions, not a reliability ranking. If the editor offers automatic sync, verify the result on a copy or a small batch, then spot-check multiple points.
Check drift and local offsets
Do not check only the start after alignment. Review the beginning, middle and end to see whether the offset stays constant, gradually changes or appears only in one section or camera. If it changes over time, record source frame-rate/timing information and the recording/import workflow. For a local mismatch, inspect edits, speed changes or track moves in that section.
Copy the project before adjustments or segmented tests. Change one condition at a time, then recheck lip sync and shared audio at multiple points.
Complete the sync in your editor
Automatic sync, multicamera sequences and timecode controls differ by editor. Use its current official help for the relevant operation, and confirm:
- which video and audio files are included in the group;
- what reference the software uses for sync;
- whether the original tracks remain available for review; and
- whether switching angles or moving clips preserves sync.
Confirm supported formats and project-exchange features in the product’s current official documentation.
Where Aixcut fits
Aixcut can be used in a later video or podcast editing workflow. Complete alignment in a tool documented to support synchronization before continuing transcription or editing.
