  • FFMPEG doesn't convert with the right Create Date on a MTS to MP4 process

    2 novembre 2020, par bob338423

    I'm on the progress of convert MTS to MP4, with intact video/audio & Creation date.

    


    This is my process :

    


    I have test.MTS and I'm I'll convert it to test.MP4.

    


    Fist.. my MTS :

    


    OSX:oo bob$ f="test.MTS

OSX:oo bob$     DATE=$(exiftool -d "%Y-%m-%d %H:%M:%S"  "$f" | grep "^Date.*Original" | awk '{print $4, $5;}')

OSX:oo bob$     DATE2=$(exiftool -d "%Y-%m-%d %H:%M:%S%z"  "$f" | grep "^Date.*Original" | awk '{print $4, $5;}')

OSX:oo bob$ echo $DATE

2018-10-26 20:53:27

OSX:oo bob$ echo $DATE2

2018-10-26 20:53:27+0000


    


    I took $DATE and $DATE2 in order to have UTC and try different options.

    


    Now, let's see what Exiftool and mediainfo sees about my MTS :

    


    OSX:oo bob$ exiftool $f | grep "Date/Time"

File Modification Date/Time     : 2018:10:26 21:56:55+02:00

File Access Date/Time           : 2020:11:02 16:12:09+01:00

File Inode Change Date/Time     : 2020:11:01 02:48:49+01:00

Date/Time Original              : 2018:10:26 20:53:27+00:00





OSX:oo bob$ mediainfo $f | grep "date"

Recorded date                            : 2018-10-26 20:53:27+00:00


    


    Up to here.. all good Date is 2018-10-26 20:53:27+00:00 (so UTC or GMT+0).

    


    Now my command to convert :

    


    ffmpeg  -i  "$f" -y -acodec aac -ab 128k  -vcodec copy  -f mp4 -metadata creation_time="$DATE" "./${f%.MTS}.MP4"

ffmpeg  -i  "$f" -y -acodec aac -ab 128k  -vcodec copy  -f mp4 -metadata creation_time="$DATE2" "./${f%.MTS}_2.MP4"


    


    I tried 2 options, $DATE (whithout Timezone) and $DATE2 (With timezone). Conversion is ok, let's see the results :

    


    OSX:oo bob$ exiftool   "./${f%.MTS}.MP4" | grep "Date"

    Seems up to here that "./${f%.MTS}_2.MP4" (test_2.MP4) is correct, but, if we check the values in epoch :

    


    OSX:oo bob$ exiftool -d "%s" $f | grep "Date/Time"

Media Create Date               : 1540580007
Media Modify Date               : 1540580007


    


    BTW, I'm now on GMT+1 (this is my local Timezone)

    


    As you can see :

    


      


    1. Conversion with Timezone (test_2.MP4) seems to be correct, except when I use epoch conversion, shows totally diferent time :

      


      Original MTS > Date/Time Original : 1540587207
MP4 without Timezone > Create Date : 1540572807
MP4 with Timezone > Create Date : 1540580007

      


      MTS >> test.MP4 >> 14400 seg (4h)

      


      MTS >> test_2.MP4 >> 7200 seg (2h)

      


      2. 


    2. Mediainfo gaves same output as exiftool..

      


      3. 


    


    ¿¿ ??? What is happening here ?. Why seems the same date but different with exiftool ?. Why 4h or 2h ?... I'm missing something here.

    


    Thanks
