Clapperboard allows to record the video using any camera (CCTV, web or action camera, built-in drone camera, etc.) and confirm its authenticity and authorship.

You should create your own account in Clapperboard and recharge your balance.

To get an authentic video you should:

Comment the video
Request a QR-code
Show the QR-code on camera making the video
The generated QR-code and the comment will be permanently placed in NEM blockchain. You will get the video from your camera.

To get confirmation that video content has no signs of modifying and was created after the QR-code had been generated you should upload the video fragment containing the QR-code to http://product.prover.io/ service. When successful, you will get the Certificate of Authenticity with video details.
