Converting audio and slides to a YouTube video

This  is a process that seemed like it would be a piece of cake but turned out to be more difficult and time-consuming than I imagined.  A couple of colleagues did a 45-minute presentation which they audio-recorded.  My task was to generate and upload a YouTube video matching the Powerpoint slides to the audio. This is what I did:

1. I opened the .wav format audio (recorded using a Zoom recorder)  into Adobe Audition.  I edited the audio to eliminate background hum and some parts that were clearly unusable or not needed.

2. I gave a copy of this edited file to the presenter’s assistant, who went through it to identify and write down start/stop points for each of the 38 slides.

3. In Adobe Audition, I added markers for the start point for each of the slides.  I converted the markers to range markers (pairs of markers that identify ranges, e.g., 2:21 – 3:07)  and then moved the ending marker for each range to the appropriate place in the timeline. (Note: I shortened this task by combining the audio segments for the last six or seven slides, which were short, into one range.)

4. I exported the range markers to individual .mp3 files.

5. I imported the Powerpoint slides into Adobe Captivate 6, and did some tweaking to make sure the slides looked good.

6. I imported the audio files into Captivate, one at a time, in most cases one audio for each slide. (For the last several slides, I used Captivate’s editor to match a longer audio across several slides. This did not seem to be any more efficient. But it was worthwhile to test this other approach.)

7. I tweaked the Captivate presentation audio and slides.

8. I exported the Captivate presentation to an mpg4 file for review by the presenter’s assistant.

9. I made a few additional edits based on her comments.

10. As requested, I broke the Captivate presentation into three parts and saved each part as a separate file.

11. I exported each of the parts as mp4 files.

Exporting a Captivate 6 file as an mp4

The export process is somewhat time consuming. As you can see, exporting a section of 11 slides took around 20 minutes.

12. I uploaded the mp4 files to YouTube, created a playlist, and added descriptions.

13. Based on feedback, I tweaked the sections (which slides are included in each section), and  uploaded the sections to YouTube again.

As you can probably tell from the above, what on first blush may seem like a simple task may sometimes turn out to not be so simple. Next time I think I will probably try a different approach. One alternative would be to import the edited audio into a full-motion screencasting program such as Screenflow or Camtasia and then record the presenter flipping through the slides in real time as the audio plays. That would probably be a less painful way to match the slides to the audio.

Or another possibility:  Video-record the presentation live.  Now that’s a novel idea. 🙂


How to inexpensively host videos that appear on your blog

It is a truism to say that video has become ubiquitous among computer users. People are constantly viewing computer videos, and more and more people are creating their own.  No doubt practically everyone who has a blog or website has considered adding videos to it. Which brings up the question of how to host videos you want to display. VideoPress and YouTube are two good options. Continue reading ‘How to inexpensively host videos that appear on your blog’

Getting started with video editing: software and hardware choices

Getting started with video editing is a challenge, but not rocket science.  There are several things to consider, including the kinds of videos you want to produce, your budget, the power of your computer, and platform.

With regard to software, for people who are new to editing video,  iMovie (Macintosh platform) and Adobe Premiere Elements (Windows) make a lot of sense. They are both relatively inexpensive and easy to learn and use. And they will help you learn video editing concepts.

The hugely popular iPad is a relatively inexpensive way to access digital content, including video, and an IOS  version of iMovie runs on the iPad.  For some, this may be an easy and affordable way to start learning how to edit video, but the capabilities of the iPad for creating and editing video content are limited.

Video basics: uploading videos to YouTube

I’ve added two videos describing how to upload videos to YouTube. One explains how to browse to a video file on your computer and upload it. The other demonstrates how to upload videos to YouTube from within iMovie. To view these videos, visit my Video Uploading playlist at my YouTube channel (laddrob).

Free Final Cut Express video tutorials

Apple’s iMovie is an excellent video editing program, but professionals use Apple’s higher-end Final Cut Pro. Final Cut Express is an inexpensive “light” version of Final Cut, and is a great tool (and great transitional program for people who eventually want to use Final Cut Pro or who can’t afford it).

If you are interested in learning Final Cut Express, you can find some good free video tutorials at
