  1. I would like to convert all my home videos to a more usable .mp4 format and am looking for a proper ffmpeg command to do the job.
    The video was captured using a Panasonic HDC-TM90 camcorder using the HA1920 recording mode.

    I would also want to make sure that the File and Media information gets copied over, specifically
    Date/Time Original and possibly File Modification Date/Time (this file seems a bit odd as it was record in Germany, but my home zone is California. times are the same but offset is different)

    The recording time should be copied to the appropriate file and metadata fields, maybe what the Windows/OS and apps like Plex use to filter/sort on.
    (Read using Exiftool)
    File Modification Date/Time
    Create Date ?
    Modify Date ?
    Media Create Date
    Media Modify Date

    Not sure if necessary or beneficial to also go from 60i to 30p.

    Any help would be great!

    Sample File:
    Input #0, mpegts, from '00066.MTS':
      Duration: 00:00:06.53, start: 0.564800, bitrate: 17280 kb/s
      Program 1
        Stream #0:0[0x1011]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p, 1920x1
    080 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
        Stream #0:1[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, fltp,
     256 kb/s
        Stream #0:2[0x1200]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090),

  2. In the mp4 container can be changed only the Track PGS(SUP) on MOV_TEXT(SRT) ex. SupRip 1.16. There is no software to support NonRealTimeMeta.
    It is better to do it in container Matroska(MKV).
    mkvmerge.exe --forced-track "0:no" --display-dimensions "0:1920x1080" --default-duration "0:50i" --language "1:ger" --forced-track "1:no" --forced-track "2:no" "-a" "1" "-d" "0" "-s" "2" "-T" --no-global-tags --no-chapters "(" "00066.MTS" ")" --track-order "0:0,0:1,0:2" -o "00066.mkv"
    mkvextract.exe tracks "00066.mkv" 0:00066.h264 1:00066.ac3 2:00066.sup

    PS I just wonder Why should to use. Some cameras record the GPS position and player should calculate our time zone.
