I then -got the gif of the spinning gears from google images. I opened the -gif up in Kdenlive and used the colorize filter to get them all -yellow so it would fit in with the puffer fish theme. - -Then I imported the overlay image (Puffy with the cutout) and -placed it on top. I then rearranged and transformed things until it -was how I wanted. - -From there I went to render the video in Kdenlive, and used the -=Video with Alpha > Alpha MOV= preset. I tried using the =webm= -presets but =ffmpeg= seems to be more picky about that, plus this -=mov= is lossless so it's better anyways. - -I then took that video and split it up into frames using =ffmpeg=. - -#+begin_src sh -mkdir movframes -ffmpeg -i bsd\ auth.mov movframes/auth%03d.png -#+end_src - -I then opened the first frame in GIMP. From there I opened the -remaining frames as layers through =File > Open as Layers=, and -selected the remaining frames using shift click. - -I then exported them as a =gif=, making sure to check =animated= in -the export menu, and set the time delay between frames. - -The =gif= that's exported from GIMP is alright, but it's not very -optimized and the timing seems to not work correctly all the time -for some reason. - -To fix this I used =gifsicle= to both optimize the gif and set the -framerate correctly. - -#+begin_src sh -gifsicle -d 4 -O3 -o output.gif input.gif -#+end_src - -After all that I finally had a great looking, small, and fast gif -with transparency. |
