How to position drawtext text

I'm trying to create a video using ffmpeg but I can't get the text watermark on the bottom right corner. It appears on the middle of the video. How should I change the following command?

-vf drawtext="fontfile=C\\:/Windows/Fonts/Arial.ttf: \
text='Stack Overflow': fontcolor=white: fontsize=24: box=1: boxcolor=black: \
x=(w-text_w)/2: y=(h-text_h-line_h)/2"

Solution 1:

Positions

• Top left: x=0:y=0 (with 10 pixel padding x=10:y=10)
• Top center: x=(w-text_w)/2:y=0 (with 10 px padding x=(w-text_w)/2:y=10)
• Top right: x=w-tw:y=0 (with 10 px padding: x=w-tw-10:y=10)
• Centered: x=(w-text_w)/2:y=(h-text_h)/2
• Bottom left: x=0:y=h-th (with 10 px padding: x=10:y=h-th-10)
• Bottom center: x=(w-text_w)/2:y=h-th (with 10 px padding: x=(w-text_w)/2:y=h-th-10)
• Bottom right: x=w-tw:y=h-th (with 10 px padding: x=w-tw-10:y=h-th-10)

Full example (centered)

ffmpeg -i input.mp4 -vf "drawtext=text='Super User':x=(w-text_w)/2:y=(h-text_h)/2:fontsize=24:fontcolor=white" -c:a copy output.mp4
