  • FFMPEG - how to add a text and crop a video at the same time

    18 janvier 2023, par ProgramadorLIXO

    Im trying to learn FFMPEG.
I am having trouble figuring out how to add a text on top of a cropped video with only one line code.

    


    I want to know how to do both at the same time !

    


    I tried something but it did not work.

    


    This is what I tried :

    


    -i GoopDeer.mp4 -ss 00:03:23 -to 00:03:33 -filter_complex "[0:v]scale=iw*2:-1,crop=1920:1088:1920:1088[Vídeo];
drawtext=text='IT'S NATHAN!!!': fontsize=100: fontcolor=white[texto];[Vídeo][texto]overlay" 10.mp4


    


    but is not correct, it's not rendering.
This is the error i got -

    


    


    bash : !' : event not found

    


    


    How do i do this ?

  • FFmpeg for marking time video based on a reference date

    29 décembre 2018, par Denio Mariz

    I am trying to mark a timestamp in a video using drawtext filter.
    FFmpeg easily marks timestamps based on localtime, gmtime or even PTS. However, I want to assign a reference time (start time) for the timestamp in order to represent the time the video was recorded (not encoded).

    Reading the documentation, I found that option basetime can be used for this purpose. However it seems that is not working or I am missing something.

    The command line I am using is :

    ffmpeg -y -i input.mp4 -filter_complex drawtext="fontfile=/tmp/UbuntuMono-B.ttf: fontsize=36: fontcolor=yellow: box=1: boxcolor=black@0.4: text='Wall Clock Time\: %{gmtime\:%Y-%m-%d %T}': basetime=1456007118" output.mp4

    By using basetime=1456007118, it was expected the start time was set to ’02/20/2016 20:25:18’ since 1456007118 is the UTC time for that time and date :

    date -d '02/20/2016 20:25:18' +"%s" # format MM/DD/AAAA hh:mm:ss
    
1456007118

    However, no error is issued by FFmpeg and the video is marked with current GMT, ignoring basetime option.

    Any hint ?
    Thanks.

    Complete information about FFmpeg version and output is :

    ffmpeg -y -i /home/denio/Videos/Interstellar_2014_Trailer_4_5.1-1080p-HDTN.mp4 -filter_complex drawtext="fontfile=/tmp/UbuntuMono-B.ttf: fontsize=36: fontcolor=yellow: box=1: boxcolor=black@0.4: text='Wall Clock Time\: %{gmtime\:%Y-%m-%d %T}': basetime=1470226363" /tmp/x.mp4
