I'm trying to use the drawtext filter in ffmpeg to add text to a video, but depending on the frame size, the text can either be too large (parts of it not even in the video frame) or too small (barely readable). Is there a way I can make the text automatically resize itself to perfectly fit the frame?

Here I am using to just put text in the top middle right now:

ffmpeg -i input.jpg -vf "drawtext=font='Impact': text='Test Text': fontcolor=white: borderw=3: fontsize-75: x=(w-tw)/2:y=h/12-th/2" output.jpg

Thanks in advance for anyone who helps.

Use the subtitles filter. Font size will autoscale to fit image.

  1. Make subtitles.srt:

    1
    00:00:00,000 --> 00:00:05,000
    Text Text
    
  2. Encode:

    ffmpeg -i input.jpg -vf "subtitles=subtitles.srt:force_style='Fontname=Impact,Fontsize=75,Alignment=6'" -frames:v 1 -q:v 3 output.jpg

  • Thanks - also do you know if it's possible, using this method, to specify the text for the subtitles without a separate subtitle file? – pigeonburger Aug 30 at 22:33
  • @pigeonburger Not that I know of. – llogan Aug 31 at 0:03
