The advantage of this method is also that you have full control of what do you want to delete from gif (every second frame (1,2,166), or every third (1,3,166)), and so on just change middle number in batch line, but be aware that if you specify (1,3,166), you should accordingly change -d14 (delay option) from process.cmd to reflect change (7msec*3/2 = 10), so instead of (7msec*2/1 = 14), option for delay should be -d10. Then start process.cmd and croped animation with every odd frame will be processed into file input.gif Then edit test.bat and change value of variable 166 from this line to match to number of frames of animation :įor /L %%i IN (1,2,166) DO echo '#%%i'> input.bat, after edit save test.bat. Gifsicle -b -U -d14 input.gif, after edit save process.cmd Look into input.txt and see what is the length of animation - how many frames it contains.Īlso look into delay of frame and if its 0.07s that means that you should put option -d14 (7msec*2) into this line in process.cmd : Then start command interpreter and type :

I think I need new more sophisticated explanation (frame delay is also important thing that should be considered too).įor this new process you'll need to download JREPL.BAT from this link :įirstly copy captured gif into input.gif file If you don't want the gif to speed up, you can use gifsicle -I input.gif to get the current frame delay, multiply it by 2 and use gifsicle -d $. The backticks ( `) around the seq command cause its output to be included as parameters in the gifsicle command line. The -f '#%g' makes it print a # before each number, which makes gifsicle understand it as a frame selection instead of a file name. The seq command just outputs a sequence of numbers from 0 to 99, counting up in steps of 2. With JohnB's sample animation, it shrinks the output size down by 27%. (If your input animation is already unoptimized, gifsicle may print a warning about it, but this is also completely harmless.)Ĭonversely, the -O2 switch re-optimizes the output animation to minimize the file size. You really want to do this before doing pretty much anything with animations, otherwise you're likely to get messy results. The -U switch will merge frames in the input animation with the preceding ones, so that each frames stands alone and doesn't depend in any others. (It's OK to use a larger number, but gifsicle will complain about it.) Replace input.gif and output.gif with the input and output file names, and 99 with the number of frames in your animation. This command should work in most Unix shells I've tested it in bash. Here's a simpler solution using gifsicle than JohnB's script: gifsicle -U input.gif `seq -f '#%g' 0 2 99` -O2 -o output.gif
