The thing is, some video data are lost during the remux as my file is smaller

If I check with MediaInfo, the video stream bit rate, bits/(pixel*frame) value
and stream size are smaller.

In your case I think the video bit rate is estimated by MediaInfo from
container size minus audio size minus estimated container overhead, and
the difference may be due to some padding bytes in the MXF stream not
copied by FFmpeg (for good reasons) and not the video stream size
itself. MediaInfo is not intended to be used for such small difference
check, at least by default (i.e. without scanning the whole file).
An additional information about if the indicated size is computed for
sure or estimated is on our ToDo-list without ETA.
