-I had a 4 webm videos (each 492x451) that I wanted to combine to be played side
-by side and I tried [iMovie](https://support.apple.com/imovie) and
-[Kdenlive](https://kdenlive.org/) and failed to do it in an easy way. I needed
-this for Github readme file so it also needed to be a GIF.
-
-The following is the [ffmpeg](https://ffmpeg.org/) version of it.
-
-```sh
-ffmpeg -y \
-  -i 01.webm \
-  -i 02.webm \
-  -i 03.webm \
-  -i 04.webm \
-  -filter_complex "\
-        [0:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a0]; \
-        [1:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a1]; \
-        [2:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a2]; \
-        [3:v] trim=duration=8, setpts=PTS-STARTPTS, scale=492x451, fps=6 [a3]; \
-        [a0][a1][a2][a3] xstack=inputs=4:layout=0_0|w0_0|w0+w1_0|w0+w1+w2_0, scale=1000:-1 [v]" \
-  -map "[v]" \
-  -crf 23 \
-  -preset veryfast \
-  trigraphs.gif
-```

-- This will produce `trigraphs.gif` that is also scaled to max 1000px in width
-  (refer to `scale=1000:-1`).
-- The important part for 4x1 stack is `xstack=inputs=4:layout=0_0|w0_0|w0+w1_0|w0+w1+w2_0`.
-- This will also cap frame rate to 6 (refer to `fps=6`) since that is enough and
-  this makes playback of GIFs smoother in a browser.
