The input has no audio, and why suggest '-async 1'? Also, libx264
ignores '-qscale', so the default of '-crf 23' will be used instead.

The actual solution is shown in the console output:

"No pixel format specified, yuv444p for H.264 encoding chosen.
 Use -pix_fmt yuv420p for compatibility with outdated media players."

Of course, another solution is to use a more capable player.
