many of the scripts here will be touched up or revised occasionally.

INTRODUCTION to the FE 'VIDEOtools' Nautilus scripts :

In 2009, I finally 'took the plunge' and migrated my mail, bookmarks, etc. from a (main) Microsoft Windows machine to a (main) Linux machine. I have documented reasons why I went to Linux, along with install notes, on an Ubuntu Install notes page

I do a lot of web page development in which a lot of photos and other image files are processed (renamed, cropped if need be, down-sized, gamma-corrected if need be, thumbnailed, etc.).

I found that I really missed the (free) Irfanview program available only for MS Windoze. I am not the only one in that regard. You can do a web search on terms like 'irfanview linux replacement image processing' and you will find many people who feel the same way.

My search for image processing replacements is documented on the FE Nautilus Scripts DESCRIPTION and Code Samples page. Writing Nautilus scripts more than 'filled the bill'.

After developing image processing Nautilus scripts, I accumulated other types of handy Nautilus scripts, whose source code is accessible via the FE Nautilus Scripts DESCRIPTION page.

The FE Nautilus Scripts are categorized into groups which are put in subdirectories of the directory $HOME/.gnome2/nautilus-scripts, in the Gnome2-Nautilus desktop and file-manager environment.

    In the MATE-Caja desktop and file-manager environment, the 'Caja' file manager looks for 'Nautilus scripts' starting at the directory $HOME/.config/caja/scripts.

The subdirectory names provide the names that Nautilus (or Caja) presents in its 'Scripts    >' submenu(s).

The names of those subdirectories are the 'script group names' or 'category names' seen in the FE Nautilus Scripts menu(s).

Here is an (old) image of the original group names in an original FE Nautilus Scripts menu.

The sub-directory names become names of 'sub-menus' of the Nautilus Scripts menu --- AUDIOtools , . . . , LinuxHELPS, . . . , VIDEOtools --- as seen in this (old, 2010) image of the FE Nautilus Scripts menu.

In particular, I have accumulated a family of 'VIDEOtools' scripts, as indicated in this (old, 2010) image of the FE 'VIDEOtools' sub-menu of the Nautilus Scripts menu.

Just below is a list of links to the source code of many of the FE 'VIDEOtools' Nautilus scripts.

The names of the scripts are fairly descriptive of what they are meant to do. The comments in the scripts provide more detail on the purpose and methods of each script. Furthermore ...

The four-part naming convention used for the FE Nautilus Scripts is explained on a FE Nautilus Scripts NAMING CONVENTION page.

Be aware of the File Safety notice posted on the FE NautilusScripts DESCRIPTION page.


I have noted elsewhere in these 'FE Nautilus Scripts' web pages that video is a 'challenging' area --- for example, a command that seems to work on one type of movie file may not work on another type.

There are three file formats involved in 'talkie' movie files

  • the video stream format
  • the audio stream format
  • the 'container' format

I have found that I get the best results when I specify all three formats for output files. So you will see abbreviations for all three format types in the filenames of many of the 'VIDEOtools' scripts below.

Many of these scripts were put together from command strings that I found on the internet. Some of those scripts were put together because I thought I *MIGHT* find them useful someday --- BUT they may not have received any test runs.

Many of those scripts are indicated by the string 'PRELIM' or 'TEST' in the filename of the script. I will remove 'PRELIM' from the filenames as I get an opportunity to test those scripts on actual media files.

List of Links to the CODE of 'VIDEOtools' scripts:

The following 2 images are used by the 04a-RULER script above.

I accumulated so many 'VIDEOtools' scripts that I had to put them in subdirectories of the 'VIDEOtools' directory --- to keep the 'VIDEOtools' Nautilius scripts menus from getting too big.

Here are 'VIDEOtools' subdirectories that contain additional 'VIDEOtools' scripts:

  • DVD-CD_vidtools/
  • VIDCAP_CONVERT/
  • multiPLAYvids/
  • vidAUDIOtools/
  • vidCONVERT/
  • vidsHTMLpages/
  • vidsJOINtools/
  • vidsToFromIMGfiles/

Below are links to the code of many of the scripts in these subdirectories.

Be aware that many of these scripts (below, and some above) are in a very preliminary (need-to-be-tested-more) form.

And some of these scripts may be in a more up-to-date form in the latest FE Nautilus Scripts package (self-extracting-script).

These scripts are not guaranteed to be in 'ideal form'. They are provided as backups and references for me --- and for 'open source' to others.

    Use the list-of-links (above) to go directly to the source code images.

    Click on a script name to see the script code. You can use the 'Back' button of your web browser to return to this page.

    If you want to download the script code, 'right-click' on the script name, and, in a popup menu offered by your web browser, choose an option like 'Save Link Target As ...'.

    Scroll down this page to look for keywords of interest in the script names.

    Alternatively, use the 'Find text' option of your web browser to look for keywords on this page. For example, when looking for examples of scripts using the 'ffmpeg' or 'mencoder' command, use a keyword like 'ffmpeg' or 'mencoder' --- or when looking for scripts that involve cropping or clipping a video/movie file, use a keyword like 'crop' or 'clip'.
