 # Videomatch
 Huggingface space where you can check if a video that came from the [Algemene Politieke Beschouwingen](https://www.tweedekamer.nl/APB) (2022) is edited in terms of timing. This space serves as an API for the [video factchecker](www.google.com). 
 
+# Usage

+2. *PlotAutoCompare*: This compares the video to the database containing full length videos of the [Algemene Politieke Beschouwingen](https://www.tweedekamer.nl/APB) (2022) and will visualize how the video matches to all the other videos in the database.
+3. *AutoCompare*: This compares the video to the database containing full length videos of the [Algemene Politieke Beschouwingen](https://www.tweedekamer.nl/APB) (2022) and will return .json-style information about how the video matches to all the other videos in the database.
