To activate SET Video Review you have to obtain a license via the sportdata online shop:
https://set.sportdata.org/wp/index.php/product-category/set-software/single-products/video-review/
You can choose between a 3-year, 1-year or event based license. For all license types the software can be installed and used on as many computers as you want. When the license period has expired, SET Video Review will run in DEMO mode again. The DEMO mode has no functional limitations, but recordings can be no longer than 15 seconds.
You will receive a license file after purchasing one of the licenses mentioned above. This file is needed to activate SET Video Review and unlock the recording-time limitation. Therefore, open SET Video Review and start the License Manager via the top menu bar. Follow the instructions of the License Manager and select the received license file when requested. If the selected license file is valid, the License Manager confirms the successful activation and SET Video Review is ready to be used without any limitations.
