Use Timecode if every camera shared jam-synced timecode, Audio waveforms if every angle recorded usable common sound, and Current frames if the only shared reference is a visible event such as a clap. Prepare that reference before creating the multicam bin, then compare an early and a late event across the angles: creating the group only starts the alignment check.

The steps below follow the [LWKS multicam guide](https://lwks.com/lightworks-knowledge-base/multicam-editing). Match its labels to your installed build. The task here is synchronizing recordings of one event; assembling a large, interrupted shoot or configuring camera timecode generators needs its own workflow.

## Prepare the sources before building a group

Import the camera recordings and any separate audio you intend to use. If those files are not in the project yet, follow the [media import and source checks](https://lightworksguide.net/editing/import-media/) first. Keep the angles for the relevant event together in a bin, with enough identity information to distinguish the cameras and takes.

Check each source's frame-rate metadata. The [documented requirement is matching or related frame rates](https://lwks.com/lightworks-knowledge-base/multicam-editing); Lightworks will not create a multicam bin from incompatible rates. Identical rates are not the only accepted case, and the guide does not provide an exhaustive compatibility table.

If group creation is rejected, fix that source-compatibility problem before assessing sync; rejected material hasn't become a group at all. Note the rates and the message you received. Switching to another sync reference doesn't confirm that the sources are now compatible.

Also identify the sound you want in the finished edit. A camera's scratch recording may be useful for matching angles even when a dedicated recorder or board feed will supply the final sound. Those are separate decisions.

## Choose the reference every angle can share

The [Synchronise using choices are Timecode, Audio waveforms and Current frames](https://lwks.com/lightworks-knowledge-base/multicam-editing). Choose after inspecting the recordings, rather than assuming the same method will suit every group.

Choose sync from a reference every angle actually recorded: shared timecode, usable common sound or the same visible event.

### Timecode needs a shared recording reference

Use Timecode when the cameras shared jam-synced timecode. A timecode field in every file is not enough: independently starting counters at zero does not mean that the same number represents the same instant of the event.

I'd pick Timecode only when the recording setup confirms that shared reference, because matching-looking clock fields can come from independent counters. Without it, check whether all angles have useful common audio or a visible event instead. Either way, the early and late checks still follow once the bin exists.

### Audio waveforms needs usable common sound on every camera

The [current guide describes automatic waveform analysis and matching](https://lwks.com/lightworks-knowledge-base/multicam-editing) when every camera recorded usable sound. A clean separate master recording does not satisfy that prerequisite for an angle whose own sound is absent or unusable. Check each camera recording.

Set the documented **analysis region**, at the start or end of the clips, and **analysis length**. I'd place that window over distinctive common sound, such as an identifiable clap or a clear shared passage, since it leaves something to inspect afterwards; a long interval of silence offers no such reference. Confirm that the intended event is present in the relevant recordings.

LWKS says Lightworks warns when some sources do not match closely. Read that warning and inspect the affected angles. If no warning appears, run the alignment check below anyway: a normal-looking group can still hold a wrong match.

### Current frames requires parking every source first

Use Current frames when there is no common timecode or usable audio but the cameras share an identifiable visual reference. The [documented prerequisite is to park each clip on that reference frame first](https://lwks.com/lightworks-knowledge-base/multicam-editing), before making the multicam group.

1. Open each intended source clip and locate the same event, such as the clapperboard closing.
2. Park every source on the frame representing that event. Check the actual action in each view, rather than relying on identical marker names or the start of each recording.
3. Only after all sources are parked, select the angles for the group and use Current frames during bin creation.

If a camera view doesn't show the chosen event, that event can't verify it, so look for another unmistakable shared moment. Current frames can't manufacture a common reference the recordings never captured.

For Current frames, park every source on the same visible event before creating the multicam bin.

## Create the multicam bin after preparation

With the sources prepared, select the intended angles and choose **Make new multicam bin**. In **Synchronise using**, choose the method supported by those recordings; for waveform matching, also set the analysis region and length. For Current frames, park the sources before creating the bin.

The guide describes the result as a multi-angle source in the Content Manager with a sync icon. Confirm that it contains the intended cameras and takes. A group name or sync icon cannot substitute for comparing the recorded events across its angles.

## Check an early and late event before cutting

Open the group and compare one identifiable event near the beginning across the relevant angles. Then compare another shared event late in the take. Use the same physical moment within each comparison: different gestures or different claps are not interchangeable sync points.

For example, compare these two patterns:

| Early event                                       | Late event                                 | Interpretation and next check                                                                                          |
| ------------------------------------------------- | ------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------- |
| One angle is two frames later than the reference. | The same angle is still two frames later.  | A fixed offset is a useful working diagnosis. Recheck that angle's timecode or chosen sync point.                      |
| One angle is two frames later than the reference. | The same angle is now twelve frames later. | The growing disagreement needs a source-timing check. Confirm the source rates and investigate the changing alignment. |

The [official troubleshooting guidance distinguishes an offset from long-take drift](https://lwks.com/lightworks-knowledge-base/multicam-editing). For an offset, it recommends rechecking timecode or remarking the sync point. For drift, it calls for confirming every source's frame rate; mismatched rates are one documented cause of progressive drift, though not necessarily the only one.

Moving an angle's start can address a constant displacement. It cannot make an increasing timing difference disappear across the entire take. If one end looks aligned after a change, check the other end again before calling the group ready.

These checks apply only to a group Lightworks has created; a rejected source combination never becomes one. If the cause stays unclear, keep the source identities, rates, chosen method and the early/late observations together for build-specific support.

## Keep the final sound independent when needed

After alignment, decide whether picture switches should also switch sound. The [LWKS recommendation for continuous dedicated audio is its own locked track](https://lwks.com/lightworks-knowledge-base/multicam-editing), so angle switches leave that sound alone.

For a board feed or dedicated recorder picked during preparation, my default is that locked track, because angle switches then leave it alone. Check it against the pictures across the intended edit before relying on it as the final sound; camera audio used for waveform matching doesn't become the listening source by itself.

![Picture switches from Camera A to B to C above one continuous locked final-audio clip.](https://lightworksguide.net/content/images/2026/10/lightworks-multicam-sync-body3-redo-v1.webp)

Align the chosen final sound, then keep it on its own locked track when picture switches should leave it uninterrupted.

If camera audio should follow the selected picture angle, include it in the switch deliberately. Listen across actual switch points to confirm the intended sound continues or changes as planned. The [track Lock control protects the track from edits](https://lwks.com/lightworks-knowledge-base/sequences-and-timelines); make the alignment changes you need before restoring that protection.

## Cut angles once the group is verified

Once the reference checks and sound choice are settled, play the synced angles and select an angle to cut to it at the playhead. For the tile workflow, first put the starting camera clip in the record sequence and arrange the chosen sound there. Focus its source tile and start playback there, rather than from the record sequence. To switch angles, [single-click the middle of the next tile](https://forum.lwks.com/threads/using-the-new-version-creators-edition-multicam-bin-no-live-edit.249528/); pressing its Play control starts or stops playback. The [documented switches become ordinary editable cuts in the sequence](https://lwks.com/lightworks-knowledge-base/multicam-editing). I'd refine a picture switch with [Move Cut](https://lwks.com/lightworks-knowledge-base/trimming), which lengthens one side and shortens the other without changing the sequence length; slipping a source would change its alignment instead.

If simultaneous angle playback is too demanding, the guide provides a **Concurrent playback limit** to control how many angles play at once. Lowering that limit is a playback-performance adjustment; it does not correct an offset, repair growing drift or confirm that the chosen sync reference was right.

Whenever you change a source alignment, recheck the relevant early and late events, then listen across the edited sequence with the intended final audio. Once both hold, keep cutting on a verified reference, with angle selection and playback performance left as separate decisions.
