Comment (by ffmpeg.pete):

 Update: I made all the files uniform in height and width using imagemagick
 command

 - resize all input files to 64x64
 - set background black
 - pad as necessary
 - center resulting

 mogrify -path 64x64/ -resize 64x64 -background black -gravity center
 -extent 64x64 *.jpg


 I confirm the output file size in the directory 64x64/ to be 64x64 in
 size:

 ...
 00001_00.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density
 1x1, segment length 16, baseline, precision 8, 64x64, components 1
 ...

 Same result. So maybe I'm not allowed to create such a small mp4?

 But!!! The input files are DESTROYED.

 Even for stupid users like me. This should never happen.

 Noticing lots of messages like this:

 [swscaler @ 0x55a8763ab600] deprecated pixel format used, make sure you
 did set range correctly

 But the images look fine on inspection.
