Always remember about the author of the video and his remuneration. Whatever you do in your business place, you'll be showing the video exactly for commercial purposes. To secure the rights for public showing, you need to sign a license agreement. If you order a video from the producer, then specify the party of the agreement to which the rights of use the video are transferred. If you work with an ordinary person with a camera, then ask him for written consent. In general, this issue is not relevant in Russia and is just often forgotten about it. This is because, it's always easier just to download the video and put it in playback. But it's important to understand who is the copyright holder and take into account the size of your chain. The bigger your chain, then the bigger the penalty and then stronger the reason to note the fact of translation on the video camera and file a charge against you. What is the most interesting, in Russia, the violation of copyright according to the Article 146 of the Criminal Code of the Russian Federation, in the case of a particularly large violation, the head of the enterprise may be sentenced for up to 6 years imprisonment.
