Spark Gap Video Editor for ffmpeg
The Zippy Clipper
Installer
Due to recent releases of Ubuntu (25.04) and Linux Mint (22.2), several changes
have caused problems.
The most reliable way to install on a Debian-based system is to download
and decompress the file (see below) on your desktop and, from the zgr-zippy directory,
do the following:
sudo ./DebInstall.script
configure
make -B
sudo dpkg --install sgr-zippy-amd64.deb
Where VERSION describes the version of Linux you are using.
The second command will install from standard system repositories
any missing packages needed to run the sgr-zippy code. Do not be
suprised if on most systems, many packages will be installed.
An sgr-zippy directory will be created in your home directory.
Place videos you wish to edit in /home/YOU/sgr-zippy/videos/.
Note: you may see a message the ffmpeg library libavformat61 is being
uninstalled as a result of the apt command. This is because the version
installed by Ubuntu, as of this writing (libavformat61), is incompatible
with the version of ffmpeg (version 7) in the Ubuntu software repositories.
The correct version, libavformat60. will be installed instead.
FFmpeg is a free and open-source software project consisting of a suite of libraries
and programs for handling video, audio, and other multimedia files and streams. At
its core is the command-line ffmpeg tool itself, designed for processing video and audio
files. It is widely used for format transcoding, basic editing (trimming and concatenation),
video scaling, video post-production effects, and standards compliance. (Wikipedia).
Unfortunately, ffmpeg is, as noted, accessed as a command-line application with a sysntax that
places it out of reach of most people.
The purpose of this code is to introduce a graphical user interface front-end
for several popular ffmpeg capabilities. The ffmpeg GUI is written in C and uses
GTK 3, Glade, VLC libraries as well as ffmpeg and related code.
The user selects files, settings and other options from the GUI and the code
translates these into an ffmpeg command which is executed.
For example, to join two video clips with a wipedown overlap, the GUI user selects two videos
from a list by checking boxes and then clicking the wipedown button. This translates to something
like this:
Which is executed and the resulting video (tmp.mp4 in the above) is renamed to a filename based
on the input.
Many common video operations have been encoded and more will be added. Suggestions welcome. The code is
under development and seriously messy. Try not to look too carefully for style. There isn't any...
Notices
The interface has been simplified and some content is hidden until requested. See the buttons
in the box on the lower right of the main screen These cause other frames to appear/disappear.
A new panel showing a frame from each video in a tiled arrangemnt is now available. Click
the Video Tiles button on the main screen, center bottom. This will display the tiles page.
You may drag/drop tiles as needed.
Please click the Re-Scan Dir button to update the tiles, entry boxe and times when ever you add or seriously modify
the contents of the video directory.
This project is unaffiliated with ffmpeg. All errors, mistakes, and stupid code are mine alone.
The HowTo videos are stored on a server in order to minimize the size of the distro and to permit
updates as needed that can be seen by all. Clicking the HowTo button loads a list of
URLs from the HowTo directory. You may play these in the Zippy Clipper directly if you have internet access.
Click the Re-Scan Dir to restore access to local videos.
The main development platform is Linux Mint with Mate. The present version of Mint is 22. The Mint X theme with WinMe borders.
Other platforms are checked and updated when time allows. Due to systems update, etc., they may not all work
at the same time.
