How to position drawtext text

Question

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

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

See drawtext filter documentation for more info.

can we dynamically change text before recording each frame?

[Elisa Cha Cha]

@user924 The text position or the text content?

[user924]

Text content. I want to record timestamp (yyyy-mm-dd hh-mm-ss)

@user924 See this answer.

Thanks, @LordNeckbeard in person for helping me for most of my ffmpeg related queries. Have a great day!

Failed to inject frame into filter network: Invalid argument -filter_complex "pad=height=ih-40:color=#71cbf4,overlay=x=w-tw-10:y=h-th-10"

@JamieHutber There are too many things wrong with your command to fix it in a comment. You should make a new question. Make sure to show your full command and also include the complete log from the command.

Thanks very much Logan for the very fast reply. I have managed to get it into the top right overlay=x=(main_w-overlay_w)-30:y=(main_h-overlay_h)/(main_h‌​-overlay_h)+30 I will raise a quesiton now

Thank you, but you actually missed the one I wanted, bottom center ;)
