! Note !
More scripts may be added --- and NO DOUBT
many of the scripts here will need to be
touched up or revised occasionally.

(Video formats are a notoriously
'dynamic' area, even after 2010.)

'VIDEOtools' FE 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' mentioned above.

The 'FE Nautilus Scripts' are categorized into groups which are put in subdirectories of the directory


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    > '


The names of the FE subdirectories (the FE 'script group names' or 'category names') are shown by the Nautilus file manager as the names of the 'Scripts' submenus.

The sub-directory names become names of 'sub-menus' of the FE Nautilus Scripts menu

  • AUDIOtools
  • . . .
  • LinuxHELPS
  • . . .
  • VIDEOtools

as seen in this (old, 2010) image of the FE Nautilus Scripts menu.

I have accumulated a family of 'VIDEOtools' scripts, as indicated in this (outdated, 2010) image of the FE 'VIDEOtools' sub-menu of the FE Nautilus Scripts menu.

(Poke this image link to see the menu cascade
in a separate browser window or tab.)

There are many more VIDEOtools' scripts now --- and the names are more descriptive.


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/usage' considerations (no worries) posted near the bottom of the FE NautilusScripts DESCRIPTION page.

Video formats in the script names
(container, video, audio)

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.

Video Sub-menus

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

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

  • DVD-CD_vidtools/
  • 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 'download' 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.

How the code samples are presented
--- and download notes :

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 search 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'.
