Last Saturday saw the campus taken over for Edge Hill’s winter Graduation ceremonies and I was there to see the Real Jenny Barrett graduate.

We’ve been streaming graduation ceremonies live online since Summer 2008 – I blogged about the use of eStream at the time – and the system has worked very well and allowed us to both stream to people watching at home and keep an archive of past ceremonies.

As I said in the previous post we were particularly pleased with the quality of video compared to other platforms such as YouTube and hosting ourselves offered more flexibility for embedding in our site.

But that was then and this is now and as you would expect, cloud services have upped their game.  YouTube now supports full HD, videos are available on a range of platforms from mobiles and tablets to TVs as well as watching on the YouTube website or embedding into our site. Combine this with the additional visibility that publishing to YouTube gives us as students share videos with friends.

So for the last couple of years we’ve been using a hybrid of live streaming with eStream and a Flash Media Server hosted in-house and uploading the archived footage to YouTube. Patiently we’ve been waiting while Google first launched streaming for some major events, then last year introduced Hangouts On Air but with a “Google+” DOG burnt into the corner of the video.

Finally in August, Google lowered the subscriber threshold for enabling live streaming to below the level that Edge Hill’s account has and we gained access to the fancy “Live events” screens:

Technically the process is very similar to what we had previously: a PC in the control room captures the mixed video output from a Tricaster, encodes it using Flash Media Live Encoder but instead of pushing to our own Flash streaming server, the feed is sent to YouTube who handle transcoding and sending out to viewers.

Colleagues in Learning Services were manning the desks but from a viewer’s perspective it went very well. The public feed ends up with about a 30 second delay from live after it’s been through YouTube’s processing but as long as people sat in the audience aren’t trying to tune in that’s not noticeable.  The feed resolution is comparable to what we had previously but at 480p it seems subjectively better quality and on mobile devices it looks great.

December ceremonies have historically had lower live stream views than the summer ones (fewer people on campus) but we had up to 61 concurrent connections watching for an average of 17 minutes:

You’ll see we ran a single stream all day rather than individual events. This made it easier to manage from the control room as FMLE could be set up once and run all day but it means that the individual ceremonies must be uploaded again for the archive – it’s not possible to use YouTube’s online editing tools for videos over 2 hours long.

Overall I’m very happy with how it went. We’ve purchased a new video capture device which unfortunately we couldn’t get to work in time but that will offer additional future proofing and the ability to stream at up to 1080p!

Update: it looks like now all YouTube users of good standing will be able to stream through both YouTube live and Hangouts On Air.
