We’re just starting to record the video inserts for a new online training course we’re developing. As I’ll presenting at the TCUK 2014 conference on on this topic, I thought I’d take a few photos in case they come in handy during my TCUK presentation.
We record the presenter actually presenting the slides, as this results in a more natural presentation style. The presenter sees the slides on the laptop, and we use the laptop’s camera for recording the video.
Previously, we’ve recorded to a white background, but for this course, we’re going to be using a green screen. We record the audio using a USB microphone and a digital voice recorder. This means we have two audio recordings of the presentation.
The presenter sees a copy of the slides on the laptop screen, which he can progress through using a remote control. He also sees the script via a teleprompter on a tablet.
The green screen (we use chroma-key to remove the background) is giving us more consistent results than having a white background.
It’s a comparatively low budget setup, and it seems to work.
Screencasts and video based learning content are growing in popularity, and we’re seeing a rise in the number of enquiries for this type of content.
Estimating the time required to develop this type of content can vary quite considerably. The easiest way to estimate the time required is to use metrics based on the duration of the screencast or video.
A simple walkthrough of a task or applications screen can take between 10:1 (ten minutes to produce one minute of a screencast) and 100:1. The most generally quoted figure we’ve seen is 30:1.
If you want to add audio to your screencast, this is likely to be closer to 200:1. That’s because you’ll probably need to write a script, record the audio, adjust the audio quality, add the audio to the animation, and so on.
If you want to include video of a presenter, this will make the presentation look more professional, but it will mean you’ll need to allocate more time to development and production. In this case, you’ll be looking at a ratio closer to 300:1.You can reduce the time by using avatars (images of a presenter) instead of a real presenter. Adobe Captivate comes bundled with sets of avatars to help you do this.
Another factor is the level of professionalism you want to achieve. It can take time and effort to produce high quality audio and video. Lighting, in particular, can be a challenge. Adding quizzes and exercises will also have a significant impact on the time required. Creating your own music bed (a musical background to the narration) will also increase the time required. In the past, we’ve purchased audio background music files under licence, as it saved time.
What’s your experience? How long does it take you to create this type of content. Please share your thoughts below.
Screencast videos have become a popular means for delivering “how-to” information. One of the questions developers must address is, how long should you make your screencasts?
At last weeks’s tekom conference, I saw an interesting presentation by Melanie Huxhold and Dr Axel Luther of SAP on how they develop screencasts for SAP’s products (Produkt- und Lernvideos als ideale Ergänzung zur klassischen Dokumentation). In their presentation, Melanie said they had determined the ideal length for their videos by sending out a questionnaire to users, asking them what they preferred.

Mozilla has released Version 1 of Popcorn Maker, a free HTML5 Web application that enables you to create videos that interact with images, text, maps and other media.
This means you are able to add live content to a video. For example, if you have a video telling a user how to purchase an item, you could include details on the specific item they want to purchase, within the video.
Mozilla is promoting this as a tool for video makers, but it offers new capabilities to those involved in corporate training, support and user assistance.
In the upcoming weeks, Cherryleaf be advising our clients how they can use the technology in their training videos and screencasts.
