Trim video clips accordingly, otherwise an error message will be displayed and the **Mix** is not applied. You can add a **Mix** either by double-clicking the line between the two clips, or by selecting one of the clips and pressing :kbd:`U`, or clicking the |composite-track-preview| icon in the timeline toolbar. .. note:: When using :kbd:`U`, Kdenlive tries to place the transition at the most logical spot. First, if there is a clip after the selected one, the transition is put between the selected and the one right after it; if there is no clip after the selected one but one before, the transition is put between the clip before and the selected one. .. figure:: /images/effects_and_compositions/transition-mix.webp :align: left A **Mix** transition in the timeline. Note the toolbar button (top left) and the transition properties on the right. By default, Kdenlive creates a transition for one second based on the **Luma** composition. The transition properties change depending on the selected transition. :1: :guilabel:`Composition Type`. Select a different one from the drop-down list if needed. See this list of :doc:`available transitions `. :2: :guilabel:`Wipe Method`. Select a built-in method from the drop-down list, or select **Custom** to use a greyscale image (:file:`.pgm` format) from your local file system. See this list of :ref:`available wipe methods `. :2a: :doc:`Adding transitions ` by downloading and installing additional wipes from the KDE Store\ [1]_. :3: Adjust the :abbr:`feathering (Smoothing or blurring the edges of a feature)` of the transition.

[1] Kdenlive has a direct link to the |kde_store| from where you can download and install new transitions in form of luma files (greyscale images of type :file:`.pgm`). Click on the |edit-download| :guilabel:`Download` icon. If you have an active Internet connection, Kdenlive queries the KDE Store for all of the luma files available and opens a dialog window.
