After some effort, the final batch of videos we made in conjunction with the London Mathematical Society (LMS) have now gone live on the Imperial YouTube channel.
The final 6 videos now concludes the upload of all of the remaining LMS lectures in our video archive. The previous blog about the LMS videos explains all the details of how and why we recorded them, so going there will fill in all the gaps. As usual, it was the same old problem and story of oxide and goo shedding from the U-matic videotapes. I explained all of this in the blog about beating the goo, but it involves taking the cassettes apart (seen on the left with just the spools of tape showing) and heat treating them. Needless to say, this is a time consuming process taking at least a day before you can find out whether or not the tape will playback well enough to digitise. If not, then you start the process all over again! So a good few weeks went by before I could end the upload process.
