In order to apply watermark to a source video, a preprocessing operation is required in the content encoding process. A watermark value (0 and 1) is inserted in the original uncompressed video frame to generate output as two sets of encoded video. (A/B variants)
The inserted watermark value is encrypted using a secret key unique to each content service provider, and can not be extracted from the outside arbitrarily.

The watermark preprocessing can be done using FWM CLI Packager, preprocessing library or SaaS packaging service depending on the customer’s choice.
