In general, we use Adobe Captivate for the creation of e-learning materials. Captivate provides a very workable, extensive interface for the creation of application based training materials, such as using the University Collaboration System (UCS). The challenge is that since Captivate creates its content in the Flash format (.swf files), the same files cannot be displayed on an iOS device such as the iPad. This could potentially limit the audience for our training materials.
I upgraded my current version of Camtasia to 7.1. If you aren't familiar with Camtasia, it works similar to Captivate, but has different output options, and is more of full-motion movie creator than Captivate. Where Captivate creates simulated mouse movements, Camtasia records in real time.
You can record a PowerPoint with audio, animations and the like, simply by creating the PowerPoint in advance, then using Camtasia to "record" your presentation. You can also do screen recordings as well, either of the entire screen or an application. The major drawback from my perspective is that the audio track really needs to be recorded in real time. Unlike Captivate, you cannot easily time events on the screen, such as mouse movements and highlight boxes, to match the audio as easily.
Given this and some other minor limitations, the focus of my investigation was to see if I could take an existing Captivate movie, bring it in to Camtasia, and output a compatible iOS file. What I found was that while the process may have some intermediate steps, it is not overly complicated, and could potentially fit the gap in our training production cycle for mobile devices that don't use Flash.
I began with a simple PowerPoint with no audio. Camtasia was very good as recording it, and I had no problems in bringing the raw capture into the editing tool. I added a title slide, some audio for an introduction, and then output the file in an iOS compatible format (in particular for the iPad). I moved the file to Dropbox, then opened Dropbox on the iPad and viewed the file. The quality of the PowerPoint slides was excellent, the opening title and music were fine, and the transition between the opening and the first slide worked well.
Next, I repeated the process, but added a "picture-in-picture" feature that Camtasia has. Using the embedded web cam on my laptop, I repeated the same process as before, with the same PowerPoint file, but used the PIP feature to provide some additional narration to the slides. I followed the same output process, and again, it worked very nicely on the iPad. I would note that I chose not to include the slide notes as closed captions, even though that feature was available, and was a one click option.
An aside here in regard to accessibility: Had I chosen to use the slide notes, they would have appeared as closed captions without my having to do anything further with them. I also like the idea of the PIP for inclusion of a sing language interpreter. I can see a work flow where the presenter is narrating the content of the slide off camera, while the PIP is on the signer. I don't think that the inclusion of both the PIP and the closed captioning would be a good idea, since the captioning box is partially obstructed by the PIP window. Note that the closed captioning window appears automatically, so there is no button to click to activate it.
Next, I took an AVI movie with audio and imported it to the Camtasia library, and then created a project around it. Output to the iPad, it worked as I expected. I did notice that the quality was degraded, but I surmised that this was due to a couple of factors, such as the original capture resolution and the resolution that I was using for the Camtasia movie. The movie was still of average quality, but not of the high-definition quality that one has come to expect. The AVI that I used was from a straight Camtasia capture.
I would note that Camtasia will not import an AVI file that it has not created. Apparently there is something in the codec that it uses for AVI movies that is different.
My next experiment was to import a SWF file, and attempt to get Camtasia to create a file from it. I had no luck in getting the SWF in - again, a flavor issue. I did notice from the menu selections, that I could bring in a MOV or M4V.
Note on Captivate: while not widely used, you can publish a Captivate movie to an F4V format by selecting Media in the publish window. I have experimented with both the F4V Video and the F4V with fixed frame rate options. I used an existing Captivate base file, and converted it to both media formats. The F4V Video format created an interesting video.
The audio track played as designed, but the video (the slides) were displayed for a very short time, and then moved on to the next slide. For example, a four-plus minute video was only slightly less than one minute when converted to a F4V video. On the other hand, the F4V with fixed frame rate created the entire movie with audio, highlight boxes, etc. in the proper location and timing.
I launched the Adobe Media Encoder, part of the CS5 Master Collection. Using the Media Encoder, I converted different types of movie formats to other formats, specifically MOV and M4V. These proved to be not much of a difference in quality or in time of conversion. I did notice that the processor must be devoid of any other business when making the conversion. A four-plus minute video (in the F4V fixed frame rate version) only converted to about 2:45 when the computer processor was stalled a couple of times.
When I brought the converted movies into Camtasia, they integrated well. I noticed that the image quality was again in the good range, but not HD quality. The movies were readable and easy to follow, just a bit grainy. Audio did not appear to have any issues, other than where the conversion had stalled there was a skip to the next section. Otherwise, they were in sync with the video
Next, I took a native Captivate file and had Captivate re-size it before creating the movie. In the example that I was working with, the native size was 800x600. The Camtasia converted size for the iPad is 620x480. Using the tools in Captivate, I converted the file to 620x480 before publishing it. Again, I used the F4V fixed frame rate media option. After publishing, I then took the F4V file through the Media Encoder and created a MOV file.
The MOV file was then brought into the Camtasia library and moved to the time line. Again in this case, everything went smoothly. The audio transfer was clear, and the video quality was of good quality.
I will continue to work with different formats, screen resolutions and combination's of factors to see if the video quality can be enhanced when the movie is brought from Captivate to Camtasia.
In summary, I think that there is potential for the use of Camtasia as a means of creating both accessible and mobile content that can be used on iOS devices. There are some technical issues that need to be further explored. While we have a good workflow for development of the Captivate movies, a good workflow needs to be developed for the process of conversion.
I invite anyone who would like to review this process, or these applications further, to contact me.
