It runs through the images twice: pass 'a' to work out an optimal colour palette, then pass 'b' to actually create the gif file using the created palette. I wrote a tiny script to do the job so I don't have to remember.

-vf scale=512:-1: set the width, scale height proportionally, usually to reduce size and save spaceįfmpeg can do it all for you but it is really hard to get your head around it.

-framerate 60 and -r 15: assume 60 FPS on input images ( ffmpeg cannot know otherwise since no FPS data in images as in video formats), pick one every 4 images so reduce size ( 4 = 60 / 15).

-pattern_type glob: convenient way to select images.

The important ffmpeg options I wanted to highlight are: under a wide variety of build environments, machine architectures, and configurations.To complement this answer: wget -O opengl-rotating-triangle.zip It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. No matter if they were designed by some standards committee, the community or a corporation. It supports the most obscure ancient formats up to the cutting edge. My question was, wouldn’t it be good if I could extract all of the frames in my animated logo (which has that video transparency layer – Alpha Channel) into a bunch of separate PNG with transparency!Ī quick Google later and we have!!! FFMPEG įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. So, in case you didn’t already know, PNG images are great, especially if you have a vector graphic like my logo to enable a ‘clean’ background transparency so you can overlay it like my animated video logo above. and realised that the only ‘image’ version of my logo is the one at the top of this website with a black background:

Now, I’m having a play with a few graphics bits and pieces with a friend to try and create some nice video transitions etc. The Jonnychipz Logo above is animated and runs on a loop: MOV format with an Alpha Channel, basically an Alpha Channel allows for transparency when you overlay a video file in something like OBS. Ok a quick blog here on how you can extract images from a video file.
