QTW 57 - Changing the Window Size During Playback (1-Aug-95)


Q We play sound and video on our CD-ROM as interleaved QuickTime with continuous sound and segments of video. Sometimes we have video segments that are of different sizes. Can QuickTime for Windows handle changing the video window size in the middle of playback?

A While QuickTime for Windows 2.0.3 does have limited support for multiple audio tracks, it currently supports only one video track. You will have to combine multiple video segments onto one track and manually change the window size between segments. If the video segments have different dimensions, the resulting track will have the dimensions of the smallest bounding box. You will need to display the movie in a child window and change the size of the window if you wish to clip the displayed track to the dimensions of the current segment. NewMovieController will scale or center, but not clip.
