To add an image overlay to your video you first seek to where you want to start the overlay. Then click the "Tools" menu button above the timeline and select "Overlay" and then the "Image" option or you can press the "O" key and then the "I" key. If you have an image in the clipboard then the app will ask you if you'd like to use that image else you can choose an image file from your computer. You can drag the overlay to position it over your video. You can also fine tune the position by holding down the Ctrl key (or Command key on the Mac) and then pressing the arrow keys to nudge the overlay around the video. You can resize the overlay by clicking on the "Resize" option and then dragging the round handles around the image to resize. You can crop the overlay by clicking the "Crop" option and then dragging the square handles around the image to crop. You can also zoom in on just a part of the image by resizing and dragging the zoom controls here. If you want to reset the image back to its original state you can press the Reset button. You can set some style properties for the overlay using the Style button. You can apply a shape to the overlay. You can also choose a shadow option. You can reuse style settings by clicking this button which will show a list of previous styles you used so you can easily switch back to a particular style combination. By default the overaly will have a transtion to fade in and out. You can edit the transition in or out by clicking these buttons. You can choose to fade, pop, or have no transition. Finally you can choose to adjust the opacity of the overlay using this slider or completely hide it using this button. To choose the section of video your overlay appears over you can drag these bars over the timeline to select the start and end point. You can also jump the start point to your current seek point by pressing the "S" key. Or jump the end point to your current seek point by pressing the "E" key. Its also possible to animate the overlay so it changes over time but we'll cover that in another tutorial. You can preview your overlay by pressing the Preview button which will seek right before the overlay start then play through it and stop shortly after the overlay is done. Once you're ready to commit you press the OK button or the Enter key Anytime you make a change to the recording it is automatically saved on your computer. After the overlay is added a colored span will show where the overlay shows on the timeline. If you want to later edit the overlay you can seek back to that spot on the timeline and click this icon which will bring you back to the overlay controls. And you can remove the overlay by clicking this icon. Or you can also use the undo or edit history drop down to go back in time before you added the overlay. 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.
