How to make a slidecast

On Tuesday I made a presentation in London called Learning and Knowldge Maturing at an information day for the EU Seventh Framework for Research. The previous Thursday the organisers had asked me for a copy of the presentation. I use a lot of pictures in my presentations and files are big – too big for email. So I uploaded it to Slideshare as a quick way of getting it to them. Friday, I had a message from AmitRanjan who said: “any chance this could be converted into a slidecast…the audio will add context.”

I groaned at the thought of the work but of course Amin was right: if you use mainly pictures and few words (and no bullet points) the audio is very important.

I have made a number of slidecasts before and the workflow was tricky. Send the slides to iPhoto, import into iMovie, record soundtrack in GarageBand. Import Soundtrack into iMovie, sync sound with slides, export to preferred format, upload to, Google or utube. Phew. Takes a day to do it.

This time I thought I’d give Slidecast a try. Slidecast is on-line software developed by Slideshare. The workflow is relatuvely easy. the slides were already on Slideshare. I recorded the audio on Garageband (if you are on a PC you can use audacity) as before. Uploaded it to my blog Slideshare does not host audio. Gave Slidecast the url and then used an online tool to sync up the audio and the slide transitions. The whole process took about 2 hours to produce a 25 minute slidecast. That is pretty OK for me. And slidecasts do get watched – we’ve had some 600 views already – with only about 20 of them coming from this web site.

    Steven says: “The way I make a Slidecast is to fire up Camtasia and then go through my slides, narrating as I present them.”

    I have treid making screencasts like this before. It is certainly efficient in terms of time – but I stopped doing it because I found myself thinking about the recording whilst making the presentation. at the end of the day I think live presentations and slidecasts are – as the great AKA Specials said ‘equal but different’. Each requires different forms of presenting. And that is why I do them seperately.

    Sounds great!

    That is really a nice idea. It does adds great value to presentations.

    And I did like the definition of learning and he fact that the most used system for learning is google. It is indeed part of my universe. I google everything these days and just get amazed with wealth of info I get – relevant and irrelevant info too!

    Indeed Lurking is not that. I lurk till I get comfortable to take part in it. It takes time to get involved. But active participation is much more Fun! 🙂 Thanks for sharing!

  3. Great post, Graham, and very timely for me. What is the online tool you use please, ie the one to sync slides and audio?

    Just letting you know that I enjoyed your presentation Graham and have blogged about it. I think you are so right about the role of communities of practice in how we learn. Kerrie

    Hi Graham,

    Those workflows sound pretty painful – have you thought about exporting from Keynote to Garageband – see if you don’t have iWork this ounds like it would make the price worth it.



  6. Graham Attwell says:

    Phil – thanks for that workflow suggestion. I have previous version of iWork. This might tempt me to upgrade.

    Terry – online tool is slidecast option in Slideshare. Not too obvious as to where it is. Select edit button on your slideshow page and then click on slidecast tab. To my mind, the software for timings is the easiest I have used – although t is not microsecond accurate. The only other issue is that slideshare does not host the audio. You have to upload audio somewhere and then provide an http address. However the audio streaming is very fast – none of teh long run buffering you get on some services.

    I think ProfCast ( does what you are looking for.

    News Bites


    The European Commission has published an annual report of the Erasmus+ programme in 2018. During that time the programme funded more than 23,500 projects and supported the mobility of over 850,00 students, of which 28,247 were involved in UK higher education projects, though only one third of these were UK students studying abroad while the remainder were EU students studying in the UK. The UK also sent 3,439 HE staff to teach or train abroad and received 4,970 staff from elsewhere in the EU.

    Skills Gaps

    A new report by the Learning and Work Institute for the Local Government Association (LGA) finds that by 2030 there could be a deficit of 2.5 million highly-skilled workers. The report, Local Skills Deficits and Spare Capacity, models potential skills gaps in eight English localities, and forecasts an oversupply of low- and intermediate -skilled workers by 2030. The LGA is calling on the government to devolve the various national skills, retraining and employment schemes to local areas. (via WONKHE)

    Innovation is male dominated?

    Times Higher Education reports that in the UK only one in 10 university spin-out companies has a female founder, analysis suggests. And these companies are much less likely to attract investment too, raising concerns that innovation is becoming too male-dominated.

    Open Educational Resources

    BYU researcher John Hilton has published a new study on OER, student efficacy, and user perceptions – a synthesis of research published between 2015 and 2018. Looking at sixteen efficacy and twenty perception studies involving over 120,000 students or faculty, the study’s results suggest that students achieve the same or better learning outcomes when using OER while saving a significant amount of money, and that the majority of faculty and students who’ve used OER had a positive experience and would do so again.
