Crop Video

1. Crop by Area

Sometimes you need to crop the video to remove texts, logos etc. at the bottom of the original video BEFORE feeding it into Duix Avatar.

You can use the following command in Linux:

ffmpeg -i input.mp4 -vf "crop=720:1114:0:0" -c:v libx264 -crf 17 -preset slow -movflags +faststart -c:a copy output.mp4

This will create a 720x1114 video from a 720x1280 video, by cutting out the bottom 166 pixels, resulting in an output video file with the following parameters:
