you have to hit the audio play right when you hit the video play and hope that they stay in sync. gamers it is your time to shine

sorry to safari desktop and ios safari users, webp animations get slower as they progress on those browsers
encoding options
Speed up the video & audio 2x and downscale to 80x44 pixels (we can't afford the frames)
$ ffmpeg -i band_geeks.mp4 -filter:v "setpts=0.5*PTS" -s 80:44 -filter:a "atempo=2.0" band_geeks_80x44_2x.mp4
Make the video a webp
$ ffmpeg -i band_geeks_2x.mp4 -vcodec libwebp -filter:v fps=24 -lossless 0 -compression_level 3 -q:v 40 -loop 1 -preset picture -an -vsync 0 band_geeks_160x90_2x.webp
Get the audio
$ ffmpeg -i band_geeks_80x44_2x.mp4 -b:a 64k -map a band_geeks_2x_64kbps.mp3
