3 ways of adding text using ffmpeg - imagemagick, drawtext, .ass
3 ways that I add text to videos
imagemagick - I use this to make text that I save as a .png and overlay the text onto my videos.
drawtext - an inbuilt command in ffmpeg to add text to your video
-.ass is a file that can be used to add text.
commands used in the video:
ffmpge command to insert subtitles .srt
ffmpeg -i video.MOV -vf subtitles=srttext.srt srt_output.MOV
ffmpeg command to insert subtitles .ass
ffmpeg -i video.MOV -vf ass=asstext.ass ass_output.MOV
imagemagick command to create text
convert -background none -fill white -pointsize 72 label:'Hello \nWorld - png file' label.png
drawtext command using a textfile
ffmpeg -i video.MOV -vf "drawtext=textfile=helloworld.txt:fontsize=100" textfile-out.MOV
drawtext command single line in terminal
ffmpeg -i video.MOV -vf "drawtext=text='hello world':fontcolor=white:borderw=7:fontsize=100:x=50:y=100" singleline-output.MOV
drawtext command 2 lines in terminal
ffmpeg -i video.MOV -vf "drawtext=text='Hello':fontsize=100:x=100:y=100,drawtext=text='World':fontsize=150:x=100:y=300" out_2lines.MOV
I have written a basic example of the .ass format here https://gist.github.com/afrum/64bab2d...
