Vrec was soon followed by modernized -versions of the other programs (Vinfo, Vplay, Vtime) and an -interactive editor (Vedit). Finally, VFile was rewritten for more -modularity, functionality and robustness, and various other tools were -added as needed. Also, new options were added to existing tools, and -several new video file formats were added. - - Guido van Rossum - Jack Jansen - Sjoerd Mullender - - -Overview of files ------------------ - -cmif-film.ms description of the CMIF video file format (more than a - little out of date -- read the source for VFile for - more info about new file formats) - - -These are programs with a command line interface: - -Vrec.py record video movies using the Indigo video library and - board - -Vplay.py play video movies - -Vinfo.py show statistics on movies - -Vtime.py Copy a video file, manipulating the time codes (e.g. - faster/slower, or regenerate time codes, or drop - frames too close apart) - -Vcopy.py Universal video file copying tool.
