Provide working defaults for the parameters. *** Provide entry widgets for the approximately 8-plus parameters that can be specified to 'ffmpeg' to specify the container-video-audio parameters for creating the output movie file. Also provide PROPERTIES-IN and PROPERTIES-OUT options to query the properties of the input and output files - after they have been selected and created, respectively. *** Provide a listbox widget by which to select the edit operation to be performed - CLIP, CROP, CONVERT, etc. *** Provide entry widgets for an input movie file and an output media file - along with a 'Browse' button to easily select the input file. My goals for the Tcl-Tk script for this GUI were: Such a movie-editing utility (a front-end for the 'ffmpeg' command) is the subject of this page. I had mentioned on these pages that I planned to work on at least one other 'front end' for 'ffmpeg' - for example, for clipping, cropping, audio-extraction, audio-addition, and some other movie file editing functions. Movie Capture from Computer Webcam-and-Audio - a front-end for the 'ffmpeg' command Movie Capture from Computer Monitor-and-Audio - a front-end for the 'ffmpeg' command from a WEB CAM and the audio system of a computer.from a COMPUTER MONITOR and the audio system of a computer.I recently (2014may,jun) published 2 utilities for recording a movie
