Filming our NoTube demo: Hollywood here we come

Within the NoTube project, the BBC together with colleagues from VU University Amsterdam, Pro-netics and other project partners are exploring the theme of “Internet TV in the Social Web”. Over the past few months we have been planning and building our first prototypes in preparation for the first NoTube Project Review.

Watching TV in a traditional setting is core to these initial prototypes. In the project’s spirit of reusing and adapting existing TV software, Libby installed the Open Source media centre MythTV on her TV at home. She also did various other things with bits of hardware and software to set up the demo. It works in Libby’s front room (and you don’t get a more realistic setting than that), but the set-up doesn’t transport very well to Amsterdam, where the Review will take place. This is mostly because it depends on Freeview (DVB-T) – and the selection of free-to-air DVB-T channels in The Netherlands doesn’t include BBC channels, which our initial demo requires.

For this reason (and because BBC’s iPlayer content is not available outside the UK) we decided to make a video of this part of our demo to include in the Review presentation – and to share with our NoTube and BBC colleagues.

Libby and I did a trial run a few weeks ago: we used Libby’s digital camera for filming, iMovie for editing and our own voices for the narration. We decided to make two versions of the video using the same content but different voice-overs: one describing the end-user experience and the other explaining the back-end processes. We showed the results to our NoTube colleagues at the last Project Meeting in Turin.

This was our first attempt at making a video and we learnt a number of things:

  • We shouldn’t underestimate how long it takes to make a good video
  • Pacing is crucial – some of the processes we explain are quite complex, and viewers can’t be expected to concentrate on both what they’re seeing and hearing at the same time
  • Our DIY narration was too fast for people to follow: we needed a professional to record the voice-over for us
  • There were too many freeze frames in places where we were describing the back-end processes: we needed to include some diagrams to help explain what’s going on and link it to the underlying architecture
  • Showing the same film twice with different voice-overs didn’t work: it was too hard for the audience to distinguish the difference between them

We came back from the Turin meeting with useful feedback and set to work on organising our ‘production’. We liked the suggestion from our NoTube colleague, Lora Aroyo, that we video a selection of our various planning diagrams, drawings and wireframes to illustrate the end user story. Lora helped us write a script for this and I gathered the relevant materials and made a trial video to see if the idea could work. We also re-visited the script for the demo video trying to make it more concise, and we made some simple box and arrow diagrams to show how the various NoTube services are interacting behind the scenes.

Filming day arrived. Our cameraman did a great job with lights and camera angles, and making sure that we had plenty of footage at different ranges to choose from. Editing proved more challenging: some of the bits of filming that we really liked just didn’t work with our script and our initial edits were too long. We soon realised that we had to be really ruthless with our script editing and we cut it by half. We also discovered that what read well on paper didn’t sound so good when it was read out loud. And, again, we underestimated how long the editing process would take…

In the end we just had to be pragmatic and do the best we could in the time we had (one day) before the voice recording was scheduled. For editing purposes we used our own voice-overs, but it wasn’t until we heard the voice of our professional narrator that we really appreciated how much better it sounded!
