Authoring considerations for publishing content to YouTube

Prerequisite knowledge:

A basic understanding of Adobe Captivate and YouTube

Authoring considerations for publishing content to YouTube

The resolution on YouTube is a standard 640×480, which you should consider as your recording size in Adobe Captivate. If you need to capture your screen at a higher resolution, ensure you are using a standard size e.g. 800×600 that you can correctly resize to 640×480.

When starting in Adobe Captivate, use the following steps:

  1. Select New Project.
  2. Select Software Simulation Custom Size. Click OK.
  3. Select 640×480 in the Preset Size option.
  4. Start recording your screen.

Since YouTube plays movie file formats instead of interactive simulations, I recommend that you  choose Demonstration as the recording mode. If you already have existing interactive simulations, follow the authoring guidelines outlined in the article, Mobile learning: Adobe Captivate content on video iPod devices.

Converting Adobe Captivate files for YouTube

YouTube supports uploading WMV, AVI, MOV, and MPG file formats as well as MPEG4. Using the Sothink SWF to Video converter utility, you can convert your SWF file into an AVI. Simply follow the steps as outlined in the article Mobile learning: Adobe Captivate content on video iPod devices to generate your SWF file from Adobe Captivate and convert it with Sothink.

For YouTube use, consider the following settings in the SWF converter:

  • Convert to: AVI
  • Encoder: I have been successful with either DivX or XVID.
  • Frame rate: You may want to try different frame rates, with my somewhat quirky laptop I achieve better results when I drop it from 30 to 15 or 12.
  • Video size: 640×480
  • Conversion mode: Interactive
  • Audio: If you included audio, select Record from current SWF file and choose Mono and 64k
  • Capture settings: Ensure you uncheck Auto end capture at the last frame

Tip: The conversion process is processor intensive, so you may want to turn off other programs and unnecessary system processes. It also helps to avoid text animations or reducing the recording frame rate to 12 or 15.

When the file has finished converting, simply upload your new video file to your YouTube account. Now your content is ready for subscription, rating, and commenting. And YouTube even provides the embed code to include videos in other content pieces.

</object>

Where to Go from Here

As you have seen in this article, it's very easy to develop mobile learning content for video sharing sites. Using Adobe Captivate, you can be a learning professional on the cutting edge and provide learning in formats your audience needs, so they can learn anywhere and any time.
