Convert narrated slide shows
Earlier this month, I presented a closing keynote address to a conference in Finland while I was on a cruise (I sent them a DVD with the keynote presentation, and called them from the cruise ship for Q&A after the presentation was over). Since the keynote contained many examples of digital stories, I recorded the audio with SoundStudio and used iMovie to put together the video, inserting full DV versions of each story in between my slides (converted to JPEG) with audio narration inserted. I was pleased with the quality of the videos, although I thought the slides were grainy.
I am looking for better ways to automate this process. When I search the Internet for software to convert PowerPoint to video, I find mostly Windows software. I know we have ADE licenses for Impatica for PowerPoint, although it converts PowerPoint into web pages - I do not see a video option.
I also downloaded a new product called LecShare Pro (with a Mac version!) which converts PowerPoint slide shows into these different formats: QuickTime, MPEG-4, Accessible HTML, Microsoft Word, audio only. Last night, I took the audio from the 45 minute keynote from a session that I did in Hong Kong in March, synchronized the audio clip with the slides and converted the whole thing into several formats. Since I have not registered the software ($69), there is a watermark on all of the slides, but it shows what is possible. The audio is also not compressed in the trial version, so the file is really too large to post on the Internet. But the process of synchronizing the audio to the slides was fairly straightforward, once I got started. The software worked directly with PowerPoint, but was pretty slow opening and saving files.
The software also allows recording audio directly, slide by slide, into a file. This option might work very nicely with ePortfolios created in PowerPoint. Students could do audio reflections on their portfolios with this tool, then convert them for either WWW, DVD or CD publishing.
I am looking for more Macintosh software that will help me take my audio clips and my slides, and put them together into different output formats.
but I didn't try this Mac tool .
I'll download it and have try. Thank you!
Hope this helps.
