pencil sketch with imagemagic using bash script
 

I may be using the wrong words to search but I'm not finding what I want.

I would like to take a 10 sec video, 300 frames, convert it to individual frames convert them to line drawings and then reassemble them into an animated GIF.

Both 'gimp' and 'mplayer' will do to make the frames.

Is there already in existence a script file using imagemagic that will convert the pictures to line drawings without color? Or maybe several scripts that can be put into a step through 'bash' script.

it might be easier to use Gmic
that is already built in
http://gmic.sourceforge.net/gimp.shtml

and instead of a 8 bit indexed gif you could output a mpng or ogg

Thanks guys for the information. This is enough to keep me up the rest of the night. Appreciate the help.

if you look at gmic the "help page is 140.6 K in size
and is well documented

Thanks and UNCLE. A 57 page help file. Def a print out and a big class of ice tea.

it is a big help page
but G'mic could replace imagemagick , it has for me it even replaces IM's "display" function

it works in 32bit floating-point so 8,16,and 32 bit images can be worked on
