Video File Converter

A Video Converter is provided in order to convert other video file formats, such as MPEG, to sequential PPM or PGM files. To invoke the converter, select from the Utility menu [Utility|Video Converter].

Enter the required information in the video converter as follows:

• Video source file field: This is the file that contains the unconverted digitized video. Use the browse button to locate it.
• From/To fields: This is the start and finish frame number of the video segment that you are converting.
• Every field: This determines whether all frames will be used or if some will be excluded. You can jump to every second, third, or forth frame, etc. If all frames are to be used, enter 1.
• Base name field: This is the name that you give to the file sequence.
• Start field: The first frame number of the result sequential file.
• Format option buttons: When 'same as source' is checked, the converter output PPM files if the source video is in color and PGM files if the video is gray scale. When 'gray scale' is checked, the converter will output gray scale PGM image files (which is only 1/3 the size of PPM files).
• In dir field: This is the directory where converted files go. Use the browse button to select a directory.
• Convert button: launches the convertion process.
• Abort Button: stops the convertion in progress.
