An example!

The GIFs work fine in a browser, but a couple image viewers (Xee, ACDSee) only show the first frame and give a vague loading error message.

Any chance of removing the movie's file extension so the name ends up as screencap.gif instead of screencap.mov.gif?

SlexAxton commented

This is definitely targeted at going along with pull requests, so that's ok with me re: browsers only.

I think that's possible. I'll have to read up on bash scripting for the 10000th time, but I'm sure it's nothing crazy. Happy to take a suggestion :D

commadelimited commented

Does it matter what you used to record the original video file? What did you use to record cli.mov?

SlexAxton commented

I use QuickTime (free) or Screeny (pretty).

Just save in native quality for best results.

paulirish commented

feature request: palindromic looping (back n forth)!

also the --good setting is incredible. same quality as what i got with GifBrewery but 20% of the size. dayum.

tednaleid commented

Looks like the location of x-quartz has moved to /usr/local/Caskroom/x-quartz/2.7.4, so line 5 in install.sh should be:

open /usr/local/Caskroom/x-quartz/2.7.4/XQuartz.pkg
ryanseddon commented

I kept getting this error:

Incompatible library version: convert requires version 11.0.0 or later, but libltdl.7.dylib provides version 10.0.0

I fixed it with this command brew link libtool --force

curtisblackwell commented

does this require zsh?

edit: nope. just threw the .zshrc code into my .bashrc and it works fine.

digia commented

Brew Cask put the package for XQuartz into /opt/homebrew-cask/Caskroom/x-quartz/2.7.4

If that helps anyone.

joemccann commented

Quality is pretty amazing.

Regarding "screencap.mov.gif", try:

+ GIF="${1%.*}.gif"
  if [[ $2 == '--good' ]]; then
    ffmpeg -i $1 -r 10 -vcodec png out-static-%05d.png
-   time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png  GIF:- | gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $1.gif
+   time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png  GIF:- | gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $GIF
    rm out-static*.png
  else
-   ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > $1.gif
+   ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > $GIF
  fi

If you're wondering what the GIF line is about:

$ FOO="Yep.nope.mov"
$ echo "${FOO%.*}.gif"
Yep.nope.gif
Buritica commented

use brew cask install xquartz if you get Error: No available cask for x-quartz
