Preview Control

The preview control allows you independent access to any video clip within the current playlist. You can have as many these preview controls open as you like. Each one is free to be positioned anywhere within AVP’s desktop. From this control, you can preview an entire clip without affecting the program play of other clips in the playlist. You can also edit certain properties of the selected clip, but most importantly this is where any custom geometry adjustments for a clip are made.
