• ffmpeg add overlay image to command with already drawtext

  29 octobre 2020, par fedep11

  I have two ffmpeg commands I would like to add an overlay image to both :

  


  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


  


• Creating marketing videos

  7 juin 2020, par Cengiz

  I am trying to create a marketing video with multiple images (png/jpg) after adding texts on every single image and of course with their duration. Therefor, I use several ffmpeg commands, because I am not able to do it with just one command.

  



  How can I define a text and a duration for every image before adding it to the video ?

  



  My example batch file :

  



   !/bin/bash

  



  echo "[Start]"
ffmpeg \
 -i '01.jpg' \
 -vf drawtext="\text='Stack Overflow' : fontcolor=white : fontsize=24 : box=1 : boxcolor=black@0.9 : boxborderw=5 : x=(w-text_w)/2 : y=(h-text_h)/2" \
 -codec:a copy \
 -y 'out-a.mp4'
ffmpeg \
 -i '02.jpg' \
 -vf drawtext="\text='Another Text' : fontcolor=white : fontsize=24 : box=1 : boxcolor=black@0.9 : boxborderw=5 : x=(w-text_w)/2 : y=(h-text_h)/2" \
 -codec:a copy \
 -y 'out-b.mp4'
ffmpeg \
 -i '03.jpg' \
 -vf drawtext="\text='Hello World' : fontcolor=white : fontsize=24 : box=1 : boxcolor=black@0.9 : boxborderw=5 : x=(w-text_w)/2 : y=(h-text_h)/2" \
 -codec:a copy \
 -y 'out-c.mp4'
ffmpeg \
 -i out-*.mp4 \
 -vf scale=768x420 \
 -c:v libx264 \
 -r 30 \
 -pix_fmt yuv420p \
 -y 'output.mp4'
echo "[End]"

  



  Thanks to all
