I though that I would se if I could replicate the sort of optimisation he writes about using gifsicle, for a wee bit of fun and learning. I tend to use firefox, gifsicle or even javascript. I’ve never really got a grip of that application. It is great, a reminder than some of the fun of giffing is keeping the file size down.Īlan uses photoshop.

I find sitting down to rip a gif out of a movie and crush it to as small as possible, or to script some sort of weird concoction a lot of fun. I find gifs intoxicating, not the looking at them but creating. That’s all that matters…But with what? With wine, with poetry, or with virtue, as you chose. Jim might be thinking that ( says Alan) but so far I am just having fun.Īuthor John Posted on JJCategories animatedgif, Tutorial Tags comandline, ffmpeg, gifsicle, imagemagick, jim groom Leave a comment on Commandline gifs: Cartoon The Nitty Gritty Drunken Gifs Like the cartooning of videos a couple of posts ago there is the opportunity to see and understand a bit more about film using this technique. New blog post: "Gimme the Bat" I'M COMING FOR YOU Jim Groom July 14, 2016 There is a 12/100 of a second delay, it loops forever, is reduced to 16 colors and optimised (O3).Īlong the way there are a lot of other possibilities, convert for example can adjust the brightness and contrast (and a raft of other things). You can see the gif ends up in the top folder. Gifsicle -delay 12 gifs/*.gif -loopcount -O3 -colors 16 -o. This takes a wee while, I then make yet another folder:Īnd convert all the cartoon jpgs into gifs:įor i in *.jpg do convert $i gifs/$i.gif done I then use cartoon to make a cartoon image for each jpg in the toon folder:įor i in *.jpg do cartoon $i toon/$i done I move int othat folder and make a new one: I switched to the finder and previewed the movie to find out where I want to start extracting frames, which turns out to be at 26 seconds, and I want to get 3 seconds worth at 6 frames per second:įfmpeg -ss 00:00:26.000 -i dance.mp4 -t 00:00:03.000 -r 6 jpg2/dance_%04d.jpg
In the terminal I move into the folder by typing cd and dragging the folder int the window and pressing return. I copied the download into a folder and renamed it dancer.mp4 Which I downloaded with YouTube downloader tool – Fastesttube!.
