What is the purpose of the Sync Lock feature?

The purpose of the Sync Lock feature in AVID Media Composer is to lock the synchronization of audio and video tracks. When this feature is enabled, any adjustments made to one track, such as trimming or moving clips, will automatically apply to the locked tracks, ensuring that the audio and video remain in sync. This is particularly important in editing processes where maintaining the timing between audio and visual elements is crucial for storytelling and viewer experience.

In contrast, the other options pertain to different functionalities within the editing software. Mixing audio tracks relates to adjusting levels and effects, editing video segments involves cutting and rearranging video clips, and enabling color grading focuses on adjusting the visual style and color of footage. Each of these processes is important in its own right but does not directly relate to maintaining synchronization between audio and video tracks.
