Detection is Reactive. Provenance is Proactive.
Many developers assume that because AWS Rekognition can detect celebrities and moderate content, it also handles "compliance." This is a dangerous misconception.Analysis vs. Authentication
AWS Rekognition is a powerful Computer Vision tool. It tells you *what* is in a video. It does not prove *where* the video came from or if it was modified. LexPixel is an Authentication tool. We don't care what's in the video; we care about proving its origin. Under the EU AI Act, you are required to label synthetic content. AWS Rekognition can help you find AI content, but LexPixel is the tool you use to legally mark it.Integration overhead
Setting up an AWS Elemental MediaConvert pipeline for C2PA is a massive undertaking involving IAM roles, S3 buckets, and complex JSON schemas. LexPixel's API replaces that entire stack with a single endpoint.Verdict
Use AWS Rekognition for moderation and searching your library. Use LexPixel for securing your pipeline and meeting regulatory requirements.Frequently Asked Questions
Does AWS Rekognition add watermarks?
No. AWS Rekognition is a computer vision service for content analysis — detecting objects, faces, and explicit content. Adding C2PA manifests or forensic watermarks requires a separate tool like LexPixel.
Can I combine AWS Rekognition and LexPixel in the same pipeline?
Yes, they solve different problems and complement each other well. Use AWS Rekognition to moderate and classify your generated content, then pipe compliant outputs through LexPixel to add provenance metadata and invisible watermarks before delivery.
Is AWS MediaConvert an alternative to LexPixel for C2PA?
AWS Elemental MediaConvert handles video transcoding, not C2PA signing. Combining it with a custom C2PA signer requires significant IAM, S3, and Lambda configuration. LexPixel replaces this entire stack with a single API call.
