To convert animation GIF to MP4 by ffmpeg, use the following command
ffmpeg -i animated.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" video.mp4
movflags – This option optimizes the structure of the MP4 file so the browser can load it as quickly as possible.
pix_fmt – MP4 videos store pixels in different formats. We include this option to specify a specific format which has maximum compatibility across all browsers.
