 Use the `aspect_ratio` flag to provide the output aspect ratio. The format
-should be `weight:height`, where the `weight` and `height` are two positive
+should be `width:height`, where the `width` and `height` are two positive
 integers. AutoFlip supports both landscape-to-portrait and portrait-to-landscape
 conversions. The pipeline internally compares the target aspect ratio against
 the original one, and determines the correct conversion automatically.
