It stands for a timebase of 1/90000 which is the timebase for all mpeg streams (and cannot be changed afaik). >>> -movflags +faststart -c copy CYD_copy.vob >> Sadly, output option cannot (easily) be checked for correctness. >> Using options that cannot have an effect may reduce your >> chance to get good help here (consider the increased time it >> needs to understand what's going on / what your intentions are). > > The probably wrong '+' was taken from the example in the Wiki: > https://trac.ffmpeg.org/wiki/Encode/H.264#AdditionalInformationTips > Maybe this is an error? > Because VOB also is coded with MPEG, I thought this flag may have a > positive effect. > Anyway, without the flag I get the same ffprobe data. The option "movflags" can only have an effect for mov (and friends) output, not for mpeg streams.

(The reason that these answers do not really help you is that the values are not necessarily meant for you, they typically have more meaning for developers.)
