  • With ffmpeg print onto clipped video hh:mm:ss time *from original* and hh:mm:ss total duration from original

    25 mai 2023, par Kes

    I am using arch linux and bash and ffmpeg, all are up to date and the latest versions.

    


    I am clipping a video that is 30 seconds long and wish to clip from 5 secs to 10 seconds to a new file, from the original.

    


    In the bottom right hand corner of the clip I wish to show timestamps from the original video as follows

    


      

    • in the 5th second "00:00:05/ 00:00:30"

      • 


    • in the 6th second "00:00:06/ 00:00:30"
      
etc

      • 


    • in the 10th second "00:00:10/ 00:00:30"

      • 


    


    This is an apparentley simple question(?) but the syntax of the command is not at all obvious and I am hoping an expert may shed some light on this.

    


    All I have so far for the drawtext part, which does not do what I want as it only counts the elapsed time from t=0 of the new clip, whereas I want it to show the timestamp and total duration of the original clip

    


    drawtext I started with

    


    "drawtext=text='%{pts\:gmtime\:0\:%M\\\\\:%S}':fontsize=24:fontcolor=black:x=(w-text_w-10):y=(h-text_h-10)"


    


    ffmpeg line with drawtext I have started with

    


    ffmpeg -ss 00:00:05 -i  "$in_file" -filter_complex "drawtext=fontfile=font.ttf:text='sample text':x=10:y=10:fontsize=12:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5,drawtext=text='%{duration\:hms}':fontsize=12:fontcolor=black:x=(w-text_w-10):y=(h-text_h-10)" -t 5 -c:a copy -c:v libx264 out_file.mp4


    


  • How to convert a 16:9 video to 4:3 video with top & bottom blurred video bars by using ffmpeg ?

    27 décembre 2018, par Wai Gyi

    I would like to convert a landscape video to a square video with blur bars at top and bottom.

    I tried to adapt the commands from the following link but not succeeded.

    FFmpeg : How to convert horizontal video 16:9 to vertical video 9:16, with blurred background on top and bottom sides

    So, can someone share a ffmpeg command with me ?

    Thank you very much for your help.

    Update : I tried again and get a working command. Please check and review.

        ffmpeg -i in.mp4 -lavfi "[0:v]scale=iw:iw*3/4,boxblur=luma_radius=min(h\,w)/40:luma_power=3:chroma_radius=min(cw\,ch)/40:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,setsar=1,crop=h=iw*3/4" out.mp4

  • Output a video made of several video chunks of the input video

    21 mai 2013, par mad

    I was wondering if it was possible to output a video made of several extracts of the input video.
    For example outputting a video made of the first 10s of each minute of the input.

    I know you can do it programmatically, calling ffmpeg several times with -ss and -t to make the chunks and then merge them, but is it possible to do it in one command using video filters ?
