  ffmpeg -i "video.mp4" -filter_complex "drawtext=textfile=sub.txt:fontfile=SourceSansPro-Bold.ttf:fontcolor=white:fontsize=100: box=1: boxcolor=black@0.5: boxborderw=5: x=200:y=h-th-200:enable='between(t,1,9)',fade=t=in:start_time=1:d=1:alpha=1,fade=t=out:start_time=8:d=1:alpha=1[fg];[0][fg]overlay=format=auto,format=yuv420p" -an -vcodec libx264 -r 25 -crf 17 -aspect 16/9 out.mp4

ffmpeg -i "video.mp4" -filter_complex "color=black@0:100x100,format=yuva444p[c]; [c][0]scale2ref[ct][mv0];[ct]setsar=1,split=4[t1][t2][t3][t4];[t1]drawtext=textfile=1.txt:fontfile=SourceSansPro-Bold.ttf:fontsize=100:fontcolor=white: box=1: boxcolor=black@0.5: boxborderw=5: x=200:y=h-th-200,fade=t=in:st=1:d=1:alpha=1,fade=t=out:st=7:d=1:alpha=1[txta1];[t2]drawtext=textfile=2.txt:fontfile=SourceSansPro-Bold.ttf:fontsize=100:fontcolor=white: box=1: boxcolor=black@0.5: boxborderw=5: x=200:y=h-th-200,fade=t=in:st=9:d=1:alpha=1,fade=t=out:st=15:d=1:alpha=1[txta2];[t3]drawtext=textfile=3.txt:fontfile=SourceSansPro-Bold.ttf:fontsize=100:fontcolor=white: box=1: boxcolor=black@0.5: boxborderw=5: x=200:y=h-th-200,fade=t=in:st=17:d=1:alpha=1,fade=t=out:st=24:d=1:alpha=1[txta3];[t4]drawtext=textfile=4.txt:fontfile=SourceSansPro-Bold.ttf:fontsize=100:fontcolor=white: box=1: boxcolor=black@0.5: boxborderw=5: x=200:y=h-th-200,fade=t=in:st=26:d=1:alpha=1,fade=t=out:st=28:d=1:alpha=1[txta4];[mv0][txta1]overlay=x='0':y='0':shortest=1[mv1];[mv1][txta2]overlay=x='0':y='0':shortest=1[mv2];[mv2][txta3]overlay=x='0':y='0':shortest=1[mv3];[mv3][txta4]overlay=x='0':y='0':shortest=1" -an -vcodec libx264 -r 25 -crf 17 -aspect 16/9 out.mp4

  [drawtext @ 03B2BBC0] Key '"fontsize' not found.
  
  [drawtext @ 03B14F20] Error parsing options string: '"fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text=shotName:x=(w)/5:y=(h)/1"'Error initializing filter 'drawtext' with args '"fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text=shotName:x=(w)/5:y=(h)/1"'
  
  Error opening filters!

  ffmpeg -i D:/imagesequence/background.jpg  -vf "movie='D\:/imagesequence/dpx/thumbnail.jpg' [link1]; [in][link1]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/3 [int];[int][link1]drawtext=\"fontsize=28:fontcolor=White:fontfile='/Windows/Fonts/arial.ttf':text='shotName':x=(w)/5:y=(h)/1\"[out]" D:/imagesequence/dpx/final_with_text_mod_04.jpg

• How to justify text in drawtext in ffmpeg ?

  26 décembre 2019, par Milan Tejani

  I am adding text watermarks to the video using ffmpeg command and I’ve added three lines already using drawtext in ffmpeg command. So, it works perfectly and adds three lines at the bottom left corner of the video.

  In the first line there are 25 characters, the second line contains 7 characters, and the third line contains 3 characters. These three lines are located from the left to right.

  So, I want to justify 2nd and 3rd line’s texts to the center as per the first line width.

  What I get :

  Hello World Ffmpeg
  
  
  
  hello
  
  
  
  hel

  what I want :

  Hello World Ffmpeg
  
  
  
        hello
  
  
  
         hel

  here command i used :

  ffmpeg -i input.mp4 -vf "[in]drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='Hello World Ffmpeg':x=(w)/2:y=(h)/2, drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='hello':x=(w)/2:y=((h)/2)+25, drawtext=fontsize=20:fontcolor=White:fontfile='roboto.ttf':text='hel':x=(w)/2:y=((h)/2)+50[out]" -y test_out.mp4
