Close button
The Close button closes the Advanced window and returns you to the Source tab.
Because MPEG is composed of a series of Groups of Pictures (GOPs), trimming MPEG
files may not occur at the frame that appears in the Preview window, but rather at
the nearest available GOP. Because of this, ProCoder can’t guarantee the trimming
positions of MPEG files.
Video Filter tab
The Video Filter tab lets you apply filters to your video to help improve image quality of
your source files before they are converted. These filters can be previewed in this tab, but
are applied when the video is being converted to its new format.
