Cropping a video

This page explains how to programmatically remove unwanted outer areas from an input video. For information on how to trim the timeline of input videos, see Stream mappings.

Use the crop configuration field to specify the number of pixels to remove from each side of the input video. You can add this configuration to a job template or include it in an ad-hoc job configuration.

The following REST/JSON configuration removes 10 pixels from the top of an input video. The input video is then scaled to meet the dimensions specified by the widthPixels and heightPixels fields in the specified codec for the videoStream object. The output video is then generated from this scaled intermediate video.
