Windows Issues

The current Kdenlive on Windows® (October 2018, version 18.08.2) has a few issues that have workarounds. The purpose of this wiki page is to document these issues and their workarounds.

Play/Pause Issue

Currently, if you use any method from playing the preview on Kdenlive for Windows®, the preview of your project will not play. This includes trying to use the spacebar or trying to press the play button using your mouse.

The quickest and easiest workaround is to use the Spacebar + Right arrow key. Press the Spacebar and then press the right arrow key.

If Kdenlive seems blocked hit Ctrl+Space. Now the play heat starts from the beginning and you can click with the mouse into the timeline to play from there.

Another option is to change the settings. To do this, go to Settings -> Configure Kdenlive -> Environment and change the process threads to 2 or above (this solves the bug but this block other functions).

Qt rendering crash

When switching from kdenlive for windows 17.12 --> 18.04/18.08, a Qt rendering crash appears. To make sure this doesn't happen, you need to edit the kdenliverc file in the appdata. To access your appdata, press Win + R (Windows key and R key simultaneously) and type APPDATA (all caps). Go to local and within it rename kdenliverc to kdenliverc.old.

Any critical bug

This describes the process of doing a clean install on Windows®.

Firstly, delete your normal Kdenlive folder (containing the application)

Access the Appdata folder (Win + R and then type APPDATA in full caps). Go to local and search for folder kdenlive.

Note

If you have any saved effects or clips stored in your library, make a backup of the library folder.

Then once you have backup up your library folder, delete the kdenlive folder.

Kdenlive cannot be deleted

If you want to reinstall Kdenlive, it may tell you "The file or folder is open in another program". Windows® then won't let you delete Kdenlive.

To fix this, press and hold Ctrl + Shift + Esc & expand the task manager by clicking all details. Then find kdenlive.exe & dbus-daemon.exe, and click End task for both of them.

Or download the File:Kdenlive-kill.zip. Unpack it and just double-click the batch file which kills all running Kdenlive processes.

"Clip is invalid, will be removed"

This bug can appear if you do a clean reinstall of Kdenlive (see above). Simply close and open Kdenlive once, and it should be fixed.

If this is not solving the problem follow these instructions.

Kdenlive crash

On Windows® 10: update your graphics card driver. Some crashes could occur of incompatibility of the graphics card with the newest Windows® updates. After you have updated the driver re-start the computer and try again by starting kdenlive.exe.
