To add a transition you first seek to where you want to insert your transition then click the "Tools" menu button above the timeline and select "Transition" or you can just press the "T" key to start the tool. The transition will be added at that spot and you can increase or decrease the duration using these arrow buttons. You can select the type of transition to use by clicking on the Type option which will show a list of all the transitions we offer. If you hover over any of the transitions in the list then you'll see a popup which will show an example of what that transition does. Some of the transitions also support another option called Direction which controls rotation or if the effect happens inward or outward. If you want to Preview what the transition will look like then you can press the Preview button which will seek right before the transition to start playing and then stop shortly after. Once you're ready to commit you press the OK button or the Enter key Anytime you add an edit to a recording it is automatically saved on your computer. After the transition is added a colored span will show on the timeline showing where it happens. If you want to change or remove the transition you can seek back to that spot on the timeline then click this icon which will bring up a menu to edit the transition or remove it by clicking this icon. You can also use the undo or edit history drop down to go back in time before you added the edit if you'd like to remove it. The last used tool will be listed next to the Tools button above the timeline so you can easily use the same tool again by clicking on it here. If you add a transition at the start or end of your recording then the transition will come in from an empty screen or go out to an empty screen which will be filled with whatever color you have setup for your canvas. For example if we add a transition at the start of this recording then we see it fading in from black which is the current color setup for the canvas. If you want to chose a different color you can click here and change it.
