Tested on macOS 11.3.1 with ffmpeg installed with homebrew

Use the h264_videotoolbox codec. -b:v is the bitrate flag. Using a higher
bitrate improves quality, but increases file size.

760k (include the k!) gives a nice balance between quality and file size.

ffmpeg -i input.gif -vcodec h264_videotoolbox -b:v 760k output.h264.mp4
