FFmpeg command overlay watermark speed
3 septembre 2021, par user892134I currently use the following command to add a watermark to 2GB video. This takes around an hour. I'm wondering if i can speed this up in anyway.


ffmpeg -y -i input.mp4 -i watermark.png -filter_complex \"overlay=10:10\" -c:a copy -c:v libx264 -crf 22 -preset ultrafast output.mp4



I'm using preset
ultrafast
, is there another command which can add a watermark quicker than what i'm using ? If not, how can i change command to show watermark every nth frames that won't show flicker e.g. every 5 frames ?
