What happens if you trim a segment that has effects applied to it?

When you trim a segment in AVID Media Composer that has effects applied, the effects will need to be re-rendered. Trimming alters the duration of the segment, which can impact how the effects are applied to the newly adjusted clip. Since the effects are based on specific frames and timing of the segment, any modifications to that segment require the effects to be recalculated and rendered again to ensure they align correctly with the new trim points and timings.

In this context, if you were to simply attempt to play back the trimmed segment without re-rendering, you may encounter discrepancies or visual errors because the effects are still tied to the original, untrimmed segment. Ensuring that you re-render them provides a smooth playback of the effects matched to the trimmed segment.
