Some scripts for GIF generation/manipulation with ffmpeg, gifsicle (and more to follow).

Video to GIF with linux and mac
Video to GIF with windows


Create gifs from video

The following two scripts are basically this blog entry in script form.

ffmpeg_vid2gif.sh (linux / mac ?)

# ffmpeg_vid2gif.sh --help

USAGE: ffmpeg_vid2gif.sh sourceVideo destinationGif [--fps FPS] [ --size WIDTH:HEIGHT] [--at SECONDS] [--runtime SECONDS] [--dither none|bayer|floyd_steinberg|sierra2|sierra2_4a] [--mode full|diff] [--onestep] [--gifsicle]

-f --fps                       Set the fps. (Default: 15)
-s --size                      Set the size like WIDTH:HEIGHT. -1 can be used to keep the ratio. (Default: 640:-1)
-a --at                        Where to  begin in the video in seconds or ffmpeg supported time format. (Default: 0)
-r --runtime                   Duration in seconds or ffmpeg supported time format. (Default: Till end)
-d --dither                    Dithering mode to use. One of (none|bayer|floyd_steinberg|sierra2|sierra2_4a) (Default: sierra2)
-b --bayer-scale               If dither=bayer select the pattern size in the range of 0 - 5. Lower values tend to produce less artefacts but larger images. (DISCLAIMER: i have no clue about such stuff) (Default: 2)
-m --mode                      'diff' or 'full'. 'diff' optimize the colors of moving objects at the cost of the background quality.  (Default: full)
-v --verbose                   One of (quiet|fatal|error|warning|info|verbose) (Default: quiet)
-o --onestep                   Do not generate palette before. Tend to produce worse, but way smaller gifs. Ignores dithering parameter. (Default: Not set)
-g --gifsicle                  Use gifsicle afterwards to ensure valid gifs.'. (Default: Not set)

###video2gif.bat (windows)### Basically the above script in interactive form.
To use it download ffmpegand extract it. Download the batch script and save it in the same folder as ffmpeg. Call it video2gif.bat.
If you want to burn subtitles also create an folder called fonts and save [this config] (https://github.com/SleepProgger/my_ffmpeg_utils/raw/master/fonts/fonts.conf) in it. To run it double click the video2gif.bat and follow the instructions.
This script is not supported by me as i don't have a windows install at the moment.
