I have deleted the beginning of a clip then applied a cross dissolve transition between that clip and the one before it. But now when I play it back, the deleted portion from the beginning of the clip is partially showing during playback. Any ideas how to resolve this?
Willie is right. A one-second transition includes about half a second before the incoming clip and half a second after the outgoing clip. To make sure that trimmed segment doesn't show during your transition, simply trim another half second off the video.
