Info text:
"There are some additional features to support your annotation process based on an automated video pre-analysis that can be activated here. For these features your video is processed by Machine Learning algorithms. Processing may take some time depending on the length and size of your video. Next to each feature you find indication if the pre-processing is activated, when it is done and if the feature is available. All videos are processed on Motion Bank's own processing units at Mainz University of Applied Sciences (Germany). No personalized data is produced and/or collected."
