WARN server comment 2015-11-30 05:26:50
This message is indicating that the duration of the file is so long that it won't fit into a 32-bit integer, which is used in version 0 of some of the MP4 atoms to store the duration. Therefore we have to use version 1 of those atoms which supports 64 bit durations.
However, some versions of QuickTime for windows do not support version 1 atoms, which is what this message is warning about. Unless you try to play the file in certain releases of QuickTime on Windows then you can ignore this message.
