Kdenlive Overwrite vs Insert Timeline Mode
Understanding how clips behave when dragged onto the Kdenlive timeline is crucial for efficient video editing. This article explains the fundamental differences between the “Overwrite” and “Insert” drop modes in Kdenlive, helping you choose the right mode for your editing workflow and prevent accidental disruption of your timeline layout.
Overwrite Drop Mode
In Overwrite mode, dropping a clip onto the timeline will replace any existing footage at the destination point.
- Behavior: When you place a new clip on top of an existing one, the existing clip is cut, and the covered portion is deleted and replaced by the new clip.
- Timeline Length: The overall length of your timeline and the position of all other clips further down the track remain completely unchanged.
- Best Used For: Replacing specific b-roll shots, correcting mistakes on an existing segment, or editing to a strict, pre-determined timing where downstream clips must not shift.
Insert Drop Mode
In Insert mode, dropping a clip onto the timeline forces existing media to make room for the new asset.
- Behavior: When you drop a clip into the middle of an existing clip or between two clips, Kdenlive splits the media at that exact point and pushes all subsequent clips to the right (downstream) to accommodate the new file.
- Timeline Length: The overall duration of your timeline increases by the exact duration of the newly inserted clip.
- Best Used For: Adding new scenes, introducing intro/outro sequences, or rearranging the chronological order of a video where you need to preserve all existing footage without cutting anything out.
