Final answer:
In relative grid mode, clips are trimmed and moved to snap to predetermined gridlines, accounting for musical rhythm to maintain timing and synchronization within a project, which is vital in music and audio production.
Step-by-step explanation:
In relative grid mode, clips can be trimmed and moved in a way that they snap to predefined intervals or gridlines within the timeline, which are usually based on musical rhythm (like beats or bars). This mode ensures that edits are made relative to the existing grid, maintaining the rhythmic or timing relationships between clips. When clips are trimmed, their start or end points will jump to the nearest grid line, and if they're moved, they'll shift in increments that align with the grid, preserving their synchronisation with the musical tempo or other clips.
For example, if you're working on a music project at a tempo of 120 beats per minute and your grid is set to 1/4 notes, in relative grid mode, moving or trimming a clip will adhere to these quarter-note intervals. This makes it very efficient for audio editing, ensuring that the elements of your project maintain consistent timing. It's especially useful for music production and audio post-production to synchronize audio with other elements that depend on strict timing, like video frames.
