The purpose of this section is to document these issues and their workarounds. .. _issue-directx: Title tool, display real background not working in "DirectX" backend -------------------------------------------------------------------- Something with the settings went wrong. Go to: :menuselection:`Menu --> Help --> Reset Configuration` and try again. Render problems --------------- After rendering you get de-synced audio or wrong effects or black frames at end of the last clip: Download version 20.08.1 or higher from the |download_page|. Disable :ref:`render-more_options_parallel_processing` in the render dialog window (check :guilabel:`More Options`). .. _issue-scopes: Windows issue with scopes, scopes don't show anything ----------------------------------------------------- .. note:: .. versionadded:: 21.12.2 All video scopes are working with DirectX. Workaround: Change the back-end to OpenGL via :menuselection:`Menu --> Settings --> OpenGL Backend --> OpenGL` If it is still not working go to: :menuselection:`Menu --> Help --> Reset Configuration` and try again. Audio crackling while playback ------------------------------ Change the audio driver in :menuselection:`Menu --> Settings --> Configure Kdenlive` (or :kbd:`Ctrl+Shift +,`), select :menuselection:`Playback --> Audio Backend` and play around with :menuselection:`WinMM` (Win7), :menuselection:`Wasapi` (Win10), or :menuselection:`DirectSound` to see what gives the best result. You have to restart Kdenlive after each change. Message *This application failed to start because no Qt platform plugin could be initialized* --------------------------------------------------------------------------------------------- Open :menuselection:`Menu --> Settings --> Configure Kdenlive` (or press :kbd:`Ctrl+Shift+,`). Then go to the :menuselection:`Environment --> MLT Environment` section and make sure the paths point to the same path as "MLT profiles folder". Download: :download:`qt.conf `. Put the file :file:`qt.conf` into the :file:`bin` folder (the folder where :file:`kdenlive.exe` is). First time use of Kdenlive -------------------------- This issue should be solved with version 19.04.2-6. In order to make sure :file:`kdenliverc` is correctly set up start Kdenlive twice (start -> close -> start). Then start your work. Intel graphics card driver -------------------------- Updated Intel graphics driver version leads to a corrupted Kdenlive :abbr:`GUI (Graphical User Interface)`. **Solution 1:** Open Kdenlive. Move the mouse to the top. The menus are showing up. Try to reach :menuselection:`Menu --> Settings --> OpenGL Backend` and select OpenGLES. Restart Kdenlive. This should solve your Intel graphic driver issue. .. text moved from forum: https://forum.kde.org/viewtopic.php%3Ff=265&t=161309.html#p425882 Maybe this statement helps (forum user "Windows User"): I would like to confirm that this issue seems to be mostly fixed. When I use the latest daily build of Kdenlive on Windows 10 with the latest Intel graphics drivers, I still get a corrupted GUI after opening Kdenlive. The only way to resolve this is to choose Settings > OpenGL Backend > OpenGLES from the menu. I can't see the menu when the GUI is corrupt but I can click where the menu should be. A quick test of Kdenlive after doing this seems fixed. **Solution 2:** Press :kbd:`Win+R` and type **appdata**. Go to :file:`Local` and within it open :file:`kdenliverc` with an editor. Search for ``[misc]`` and delete ``[misc]`` and the following entry. Then restart Kdenlive. .. _issue-style: Timeline right-click menu closes immediately after releasing mouse button ------------------------------------------------------------------------- Don't use the style :guilabel:`Fusion`. Go to: :menuselection:`Menu --> Settings --> Style` and choose :guilabel:`Default` or :guilabel:`Windows`. .. _issue-force_breeze_icon_theme: Icons are missing ----------------- Go to: :menuselection:`Menu --> Settings` and un-check :guilabel:`Force Breeze Icon Theme`. Kdenlive restarts and you should see the icons. Cannot open projects made with previous version, timeline snaps back, cannot import clip ---------------------------------------------------------------------------------------- Go to: :menuselection:`Menu --> Help --> Reset configuration`. If this is not solving the problem: Press :kbd:`Win+R` and type **appdata**. Go to :file:`Local` and within it rename :file:`kdenliverc` to :file:`kdenliverc.old`. Start Kdenlive, close it and then start Kdenlive again. If you have still problems delete proxy clips and other cached data by going to :menuselection:`Menu --> Project --> Project Setting --> Cache Data` where you can delete cached data. Windows 10: timeline stuttering or Kdenlive hangs -------------------------------------------------- Most probably you got a major Win10 update (i.e 1809). If so, you have to update all drivers for audio and video. Intel drivers can be updated with this |intel_updater|. Message *Clip is invalid, will be removed* ------------------------------------------ This message can appear if you do a clean reinstall of Kdenlive (see above). Simply close and open Kdenlive once, and it should be fixed. Additionally this can be a problem either with the :file:`kdenliverc` file or you have some mismatch in the :file:`%APPDATA%\\local` folder. 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 (:kbd:`Win+R` and then type **APPDATA** in full caps). Go to :file:`Local` and search for folder :file:`kdenlive`. .. note:: If you have any saved effects, or clips stored in your library, make a backup of the :file:`library` and the :file:`effect-templates` folders. Then delete the :file:`kdenlive` folder. Reinstall the latest version of Kdenlive from the |download_page|. JPG files appear as white picture after rendering ------------------------------------------------- This issue should be solved with version 19.04.0. If not, convert the JPG to PNG and it renders correctly. Play/Pause issue ---------------- This issue is solved with version 18.08.2 (30. Oct 2018). Get the current version from the |download_page|. Qt rendering crash ------------------ Hit :kbd:`Ctrl+Shift+,` or go to :menuselection:`Menu --> Settings --> Configure Kdenlive`, and then to :menuselection:`Environment` and make sure the paths point to the same path as "MLT profiles folder". When switching from version 17.12 to 18.04/18.08, a Qt rendering crash appears. To make sure this doesn't happen, you need to edit the :file:`kdenliverc` file in the :file:`AppData\\local` folder. To access your appdata, press :kbd:`Win+R` (:kbd:`Windows` key and :kbd:`R` key simultaneously) and type **appdata**. Go to :file:`local` and within it rename :file:`kdenliverc` to :file:`kdenliverc.old`. Kdenlive cannot be deleted, running process on exit --------------------------------------------------- This issue is solved with Windows version 18.12.1. Get the current version from the |download_page|. If you want to reinstall Kdenlive or re-run Kdenlive, it may tell you "The file or folder is open in another program". Windows® then won't let you delete or re-run Kdenlive. To fix this you have to kill the running process: press and hold :kbd:`Ctrl+Shift+Esc` and expand the task manager by clicking :menuselection:`All details`. Then find :file:`kdenlive.exe` and :file:`dbus-daemon.exe`, and click :menuselection:`End task` for both of them. Or download :download:`Kdenlive-kill.zip `. Unpack it and just double-click the batch file which kills all running Kdenlive processes. Kdenlive crashes at start up, Kdenlive cannot be uninstalled ------------------------------------------------------------ If Kdenlive crashes at startup or if the uninstaller doesn't work delete the entire folder: :file:`C:/Program Files/kdenlive`. Re-install Kdenlive. You may have to manually delete the Kdenlive folder in the Start menu. Kdenlive crash or green monitor --------------------------------- Get all newest Windows® updates. Afterwards, update your graphics card driver, your sound card driver and your printer driver. Some crashes could occur of incompatibility of the graphics card and sound card with the newest Windows®10 updates (18.09 update). After you have updated the drivers re-start the computer and try again by starting :file:`kdenlive.exe`. If this is not solving the problem switch your standard printer to “Microsoft XPS Document Writer” and try again to start Kdenlive. Delete the :file:`kdenliverc` file. Make sure you set concurrent threads to ``1``: Go to :menuselection:`Menu --> Settings --> Configure Kdenlive` (or :kbd:`Ctrl+Shift+,`) and then in :menuselection:`Environment --> Proxy and Transcode Jobs` set :guilabel:`Concurrent threads` to ``1``. Audio pops and ticks in render ------------------------------ The current Kdenlive version (November 2018, version 18.08.3) has audio issues that have workarounds. If this problem appears make sure the audio file uses 16-bit PCM WAV format.
