The intention of this feature is to lock elements of the timeline/clips/layers so that they cannot be accidentally changed during timeline compositing.
This can also be locked during playback without affecting the playback functionality, it should only lock the compositing features.

Timeline-Lock

With this feature, entire timelines or individual layers can be locked to prevent accidental changes during programming or playback.

Even when locked, the timeline remains fully accessible: all effects, keyframes, and parameters can be opened and reviewed, but not edited. This allows users to safely inspect the current state of a project without the risk of unintended modifications.

Not possible when the timeline is locked:

• Creating or deleting layers, cues, or clips
• Changing layer or clip settings

Layer-Lock

Individual layers can also be locked. Locked layers cannot be edited but remain fully visible for inspection. The same applies to layer groups — entire groups can be locked, or only specific layers within a group, depending on the desired level of control.

In multiuser setups, the lock status is not transferred immediately, but only when the first user pushes the timeline to the other systems. This ensures that the editing state remains clearly defined and consistent across all connected users.

Not possible when the layer is locked:

• Creating or deleting keyframes
• Editing in inner-compositing

Clip-Lock

You can lock individual clips so they can’t be selected or edited anymore — perfect when you want to make sure nothing gets changed by accident.

Locking or unlocking a clip is as simple as a right-click, so you can quickly switch things on or off while you work.

Even when a clip is locked, it still reacts to all layer and timeline adjustments. Global changes continue to apply — the clip just stays safely protected from direct editing.
