Sure enough, converting a video to the gif format could be done with one command: ffmpeg -i video.mp4 -filtercomplex '0:v split ab a palettegen p bp paletteuse' converted-video.gif.
Now it’s time to test it out! Run npm start to start up your react app and upload a video to convert (it may take a couple of seconds to convert, check the log in the console to see ffmpeg’s updates). But writing a post about using FFmpeg, it felt weird to not even try and use it in this situation.

Finally, we have a button that when clicked will convert our video to a gif ( line 52). This post describes how to use Ffmpeg directly in browser, and use native commands. We have a video ( lines 39–42) and image ( lines 53–56) view which are shown if our video and gif states are not empty.

We have input for video, start time, and length all of which have an onChange handler to update their respective state fields ( lines 43–51).
Render: This is our UI section, if we are not ready we show “Loading…” else we will show the input fields. Finally we get the result from ffmpeg’s filesystem and convert the bytes into a blob url of type gif which we can show to the user on lines 29–31. A detailed tutorial about how to use Terminal.app to convert videos to gifs. Then, we run our ffmpeg command on line 26. Convert video to GIF by using Terminal.app in macOS. ConvertVideoToGif: This is where the actual work is done, we write the video file to ffmpeg’s filesystem on line 23. t tells FFmpeg to read in y seconds of the input video and then stop. ComponentDidMount & loadFFmpeg: Here, we wait until our react component mounts and then load in the Web Assembly code for ffmpeg, then we set ready to true to indicate we are ready to convert video. If you want to convert only a part of the video to a GIF, you can add these two arguments to the command to indicate the part of the video that you want: -ss 'x seconds' -t 'y seconds' -ss tells FFmpeg to seek x seconds into the input file. Constructor: We create some state items to keep track of the current app state. Line 4: We create an ffmpeg instance and set logging to true so we can see logs in our console.
