Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.
Since v2017.12.27.1 I have got mp4 files unreadable with QT Player 7 or QT Player X (black image but audio ok) when I encode prores progressive mov files into mp4 with same setting as previous Hybrid version. However these files are readeable with VLC or IINA.
It seems that the problem is related to muxing with mp4box because mp4 files muxed with ffmpeg are readable with QT Player 7 and QT Player X.
