The major limitation of using video in the classroom is that it allows students to be too passive. If you just put a film on and have the students watch it, you are not allowing them any sort of an opportunity to interact with the lesson. Even if you are just lecturing, which teachers are encouraged not to do, students can ask questions. But with a film, the students are just sitting there, typically in the dark, and passively watching the film. At the very least, if you are using a film, you would want to have some sort of a study guide with questions that they should be able to answer as they watch. Otherwise, you run the risk of having students pay very little attention.
use of video in the classroom fails to encourage any sort of student acticity or involvement in the class. the students who are made to watch the video are not able to put up any queries while the video is going on .so, if the student is unable to understand a certain thing at some point during the video, his query remain unanswered . moreover, as it is in the case of listening it might be possible hat only a few students pay attention to what they are being shown, while others seem to pay no attention at all. Moreover, it is very easy for a teacher to explain certain difficult points amidst a lecture which is practically impossible to do during a video session. It might also be possible that the language used in the video is difficult for some to understand. In a lecture , on the other hand..a teacher can easily use easy words to which students can easily relate to.Thus according to me a lecture is much more creative session than a video.
