$ \bigcirc$Description


One major default of movie images issued by a video system is the frame effect : because each image is divided into two mixed frames (even and odd lines) taken at different times, any motion on the movie produces an undesired effect of alernated lines. This module allows to separate even and odd frames on a cmovie. From each image of the movie, two images are extracted and the missing lines are interpolated by duplication (default) or linear interpolation (-l flag). Unless -e flag is specified, the even frame is taken before the odd one.
