Videos of teacher working in the ELT classroom is pretty difficult to come by, so this makes this series of videos from the British Council that much more valuable.
As you can see from this example the videos have footage from the real practicing teachers accompanied by expert commentary. This is useful stuff for anyone involved in teacher training.
You can find the full series of 9 videos ( about 5 mins each) within the Teaching English website's Training videos section.
Hope you find these useful.
