I'm using Kdenlive to edit some video I recorded. I have some "uh"s, "um"s, and dead air I want to delete quickly. For every little bit I need to remove, I'm having to:

  1. Select track
  2. Set end cutting point
  3. Cut clip (Shift+R)
  4. Set start cutting point
  5. Cut clip (shift+R)
  6. Select portion to delete
  7. Press delete
  8. Right-click in empty area
  9. Click "remove space"

This is a real pain. :-( I'm used to Cinelerra, where you just click-drag a selection, then press delete. Unfortunately, the codecs in Cinelerra are sorely out of date. How can I speed this process up in Kdenlive?

1. How to quickly mark a segment to delete:

  1. Make sure the video track is selected.
  2. Press X to switch to the Cut (Razor) Tool
  3. Click once in the timeline at the start point
  4. Click once at the end point
  5. Press S again to switch back to selection mode

2. Use xdotool to automate delete/remove space with a single keyboard shortcut

  1. xdotool allows automation of keyboard and mouse clicks/movements; install it with sudo apt-get install xdotool
  2. Copy and paste the below to an sh file, say kdenlive_cut.sh in your home directory:

    #!/bin/bash
    DELAY=0.5 # delay in seconds between each action xdotool search --limit 1 -name Kdenlive > nul # activate only if kdenlive running if [ $? -eq 0 ] then xdotool click 1 && sleep $DELAY \ # left-click && xdotool key Delete && sleep $DELAY \ # DEL && xdotool click 3 && sleep $DELAY \ # right-click && xdotool key r; # 'R' to remove space fi

    Make it executable with chmod +x ~/kdenlive_cut.sh

  3. Open Settings...Keyboard, and go to the Shortcuts tab. Create a custom shortcut, naming it whatever you want, and setting the "Command" path to /home/username/kdenlive_cut.sh. Click Apply. The right-column will say "Disable", click on it and you'll see "New Accelerator": press your shortcut key combo. I chose Ctrl+Del since it doesn't conflict with the existing shortcuts in Kdenlive.

  4. Now go to Kdenlive, and mark a segment you want to cut (as explained in Section 1). Click on that segment to outline it in red, and without moving the cursor, press Ctrl+Del; you will see the segment deleted, an empty space appear, the right-click menu show and the space removed -- all in the space of about 2 seconds.

    • Sometimes the shortcut fails the very first time it's invoked, giving you the longer right-click menu or the "Insert Space" option. Just cancel, and try it again...it works.

    • Here's a Youtube Demo of the shortcut in action.

Despite requests of many users, there is no such function for just selecting a part and removing it out of the audio/video track.

But I think that you just could look where to cut, then cut two times, click on the middle part and then click Del. And that is everything.

I think that this cutting process shouldn't take too long.

In the new Kdenlive you can set a zone region with i and o keys and then press Shift+x to delete the region on all tracks. Unfortunately at the moment Kdenlive Version 18.04.1 you can not exclude tracks from this operation.
