• Is it possible to add stroke to text in ffmpeg ?

  1er avril 2022, par Svetlana Gajic

  I would like to add black stroke to text in ffmpeg. Is it possible ?

  



  -c:v libx264 -vf "hue=h=0, drawtext=fontfile=../bin/RobotoCondensed-Bold.ttf:text='Hello.':fontcolor=white: fontsize=158: x=0+(w-text_w)/2: y=50+(h-text_h-line_h)/2" -c:a copy -shortest -pix_fmt yuv420p ../bin/ENG_01.mov


  


• Using ffmpeg to print onto video clip actual time and duration from original clip

  24 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 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


  


• Combining audio and multiple videos with FFMPEG [closed]

  6 novembre 2023, par Lee P

  I am working on a ffmpeg script to combine two videos with one audio file. The first video file should start after about 6 seconds and the second after about 40 seconds, and there should be a padding with a black screen between the two videos.
However, it only seems to add the first video clones the final frame as the padding.

  


  Here is my current script :

  


  ffmpeg -i video_0.mp4 -i video_1.mp4 -i audio.mp4 -filter_complex "[0:v] tpad=start_duration=5927ms:start_mode=add:color=black:stop_mode=add:color=black; [1:v] tpad=start_duration=44901ms:start_mode=add:color=black:stop_mode=add:color=blackconcat=n=2" -map 2:a -f mp4 -movflags +faststart composite_recording.mp4


  


  The final video timing should be :

  


  00:00-00:06 — black screen
  
00:06-00:24 — first video
  
00:24-00:40 — black screen
  
00:40-00:48 — second video

  


  I tried setting different values for the tpad start_duration for the second video and expected it to start the second video at around 40 seconds into the audio, however it didn't change anything.
