After you've recorded audio and video for your scripted recording you can edit the video by clicking this button. This brings up the usually recording editor but there are a few special features when you are editing a scripted recording First you'll see bars on the timeline that denote where your scripted sections start. If you click and drag along the timeline you'll see a tooltip appear which points to the start of the current section and lists the text in that section. If your video recording added silence in a script section it will also be highlighted on the timeline When you seek within that highlighted part you'll see an icon on the tool bar offering some editing options for the silence. You can absorbe the silence which will make the video run faster to match the audio in that scripted section. You can cut the silence out. Or you can speed-up just the silent part which you can do multiple times if you need more speed. If you'd like to add an overlay over a complete section then you can seek to the start of the section and then choose to add the overlay which will default to select the complete section. If you need to get back to the script editor you can click the "Edit Script" button to get back.
