Mediasite Editor
Use Mediasite Editor to add finishing touches to your video― trim extra content at the beginning or end, remove unwanted content using different types of cuts, update slide images, add images (watermarks) to a video stream, or add chapters.
When you open a presentation for editing, it is saved as a project. Once you have finished your updates, you can save your edited project to the original presentation, a different presentation, or even create a new one.
