Videolab feature three different evaluation methods to provide feedback on their videos to users.

Time-specific annotations
Users can add time-specific annotations to each video by selecting amongst a set of sentiments (Positive, Neutral, Negative) characterizing the annotation. Additionally a free comment text allows one to provide further feedback perhaps providing an explanation regarding the sentiment.
Systematic feedback
Videolab features a more systematic feedback mechanism with a pre-defined set of evaluation criteria. Official forms, such as theĀ MAAS GlobalĀ are supported out of the box with easy customization mechanisms.
Videolab administrative section allows the full management of feedback forms including custom reporting.


Overall feedback
Similar to the time-specific annotations one may provide a more overall textual feedback to each video.
Free discussion
Users can easily start a discussion for all of the above-mentioned feedback mechanisms.
