PopUp
This function enlarges a photo image from 0 to full frame size within span of
zframes. It then displays the full size through the specified frame range and
shrinks back in the last zframes. The
album (with album function )clip, videoclip, the popup and endframe numbers
on album clip, frame on video clip corresponding to popup on album, are to be
specified. Audio of album clip outside the range of frames specified and of video clip within the
range of frames will be present on the output clip. For each Popup this function
need to be called. Note that since this function has no knowledge about the size
and placement of the thumbnail, the enlargement starts at album frame center,
and the image at end disappears into the album frame center. If this appears to
be not acceptable try albumpop function.
RGB32, RGB24, YUY2 and YV12 formats only are supported.
