Trimming in the timeline

Status

• It is explained clearly what the feature is supposed to do
• Same-Track-Transition has to be implemented first
• It is clear how this can be implemented in Kdenlive

Intro

Inputs:

• https://kdenlive.org/en/video-editing-applications-handbook/#trim
• Café 42 inputs

Questions:

• Is trimming by mouse needed/convenient?
  • Dragging the clip in slip/slide mode would probably feel intuitive, as would dragging the edges in roll/ripple

Summary

Trimming functionality consists of different parts:

• The logic to apply the different operations in the timeline (setting new IN/OUT points for the clips etc.)
• The user controls for using the trimming tools. This includes keyboard/mouse control, buttons, menu entries.
• The clip monitor which shows the relevant IN/OUT points of affected clips (up to 4)

Workflow:

1. Select which clip should be trimmed
   • For mouse, this is usually done with either special positions on the clip or with special mouse tools
   • For keyboard, the selection is usually controlled with the timeline cursor position and the active track and the activation of the trimming tool
2. Choose a trim tool
3. Trim the clip
