SCIRun makes a movie by recording the content of the Viewer window each time the Viewer window is redrawn. The width and height of each frame is the same size as the width and height of the Viewer control window. The width and height of each frame may be changed by clicking button Resize and typing width and height values into the resize text boxes--this must be done before recording the movie.

A movie can be saved as a series of PPM frames, one frame per file, or as an MPEG file.

When saving a movie as a series of PPM files, the files are named according to the C-style format string in the the Name: text box and the initial frame number in the Frame: text box. The frame number is formatted according to the conversion specification introduced by the percent '%' character. For example, if Name: is movie.%04d and Frame: is 1 then the following series of file names are generated: movie.0001, movie.0002, ..., movied.1000 for a PPM movie with one thousand frames.

When recording an MPEG movie, the Name: text box contains the name of the MPEG file.

Click radio button PPM to begin a PPM recording. Click button Mpeg to begin an MPEG recording. Click button Stop Recording to end a movie.
