How to Nest Timelines in Kdenlive

This guide explains how to set up a nested timeline structure in Kdenlive by importing one project file (.kdenlive) into another. You will learn the step-by-step process of merging project timelines, which allows for cleaner organization, easier management of complex video edits, and the efficient reuse of previously edited sequences.

Step 1: Prepare and Save Your Source Project

Before nesting, you must have the project you want to import saved as a standard Kdenlive file. 1. Open the project you wish to use as a nested sequence. 2. Ensure all edits are complete or saved. 3. Save the project (e.g., sequence_one.kdenlive) and close it.

Step 2: Import the Project into Your Master Timeline

To nest the sequence, you will treat the saved project file like a standard video clip. 1. Open your master Kdenlive project (or create a new one). 2. Go to the Project Bin window. 3. Click the Add Clip or Folder button (the folder icon with a plus sign), or right-click inside the Project Bin and select Add Clip or Folder. 4. In the file browser, navigate to your saved source project (sequence_one.kdenlive), select it, and click Open.

The imported project will now appear in your Project Bin as a single clip, represented by a Kdenlive project icon.

Step 3: Add the Nested Project to the Timeline

Once imported, you can use the nested project just like any other media asset. 1. Click and hold the imported project clip in the Project Bin. 2. Drag and drop it onto an empty track in your master timeline. 3. You can now cut, trim, apply transitions, or add effects to this nested clip as a single unit.

Step 4: Editing and Updating the Nested Timeline

If you need to make changes to the nested sequence, you do not need to recreate the file. 1. Open the original source project file (sequence_one.kdenlive) in a separate Kdenlive window. 2. Make your adjustments and save the changes. 3. When you return to your master project, Kdenlive will automatically detect the changes to the imported file and update the nested clip on your master timeline accordingly.
