[font=Times New Roman]I am able to view a video clip in the “preview” area, but when I want to edit the duration, and click the “Adjust Duration” button, the pop up screen “Video Trimmer” does not display an image, just a black screen, however I can hear the audio. This only happens with files that have a AVI extension, which are the files that I captured from my camcorder. It works ok with WMV file extensions. I appreciate your time and help.

in video wave go to section you want to delete. Left click mouse and split. Go to end of the where you want to finish splitting the video again and then delete the section you don't want nad continue to edit
