Comment:

 Replying to [comment:1 cehoyos]:

 Then the duration shown by ffmpeg for the input is wrong.

 To the OP, in the file header, the edit list for the track indicates that
 the stream should be repeated once.


 {{{
 track[0].edit_count = 2
 duration=570000 time=0 rate=1.000000
 Last message repeated 1 times
 }}}

 But the header appears to be malformed, since I am unable to dump the
 relevant boxes for the input due to an inconsistency in an earlier part of
 the header, which triggers an assertion failure.

 To ignore this editlist and get the expected length, use

 `ffmpeg -ignore_editlist 1 -i Bubble_burst.mp4 -c copy Bubble.mp4`
