Die aufgenommenen Videos lassen sich im Flashformat (SWF und FLV), Silverlight, QuickTime (MOV), RM, animiertes GIF, AVI oder iPod-video-Format speichern oder gleich in eine ausführbare EXE umwandeln. Camtasia Studio bietet besondere Effekte für Mausklicks oder Tastatureingaben und kann Cursor-Bewegungen automatisch verfolgen oder in das Bild hinein zoomen. Dank der ebenfalls integrierten Bearbeitungs-Funktionen können die erstellten Filme auch gleich geschnitten, editiert oder exportiert werden. Auf Wunsch lassen sich die Videos oder die daraus erzeugten Einzelbilder sogar vertonen oder mit einem Untertitel versehen. In der Version 6.0 können Sie Videos in HD-Qualität erstellen und eine 3D-Perspektive verleihen. Alle Änderungen und Neuerungen finden Sie in den offiziellen Release-Notes auf der Homepage des Herstellers.
