Thank you. I hope I get time to produce more videos after the vacation period. I believe videos can be a very good complement to written material. Unfortunately, both things takes rather long time to produce. It has take around 20 hours to produce and publish those 4 minutes of video.

I believe that some people can do most of such a video in a few live recordings, but that does not work for me. I cant help saying wrong things and use the mouse to point to things, and a lot of other things that I didn't intend to do. And then you eithe have to start over or try to produce the final video from several "scenes", but that can easily result in some strange "jumps".

So (should anybody be interested) I have done it like this:
  • I obviously first considered what the video should be about.
  • Then I created the script and an initial sound track using the synthesized Amy voice (ivona.com)
  • Originally, I would just have used the free version as an intermediate sound track, but I had a cold and nearly no voice, so I purchased the rights and added Amy to (the first version of) the final product.
  • While playing back the sound track in the media player, I record the video in one contionous real time take using Camtasia Studio (this was by far the simplest and fastest step).
  • Then create zooms, callouts, etc in Camtasia Studio.
  • That gave the first verson of the video with Amy, but I thought that it would be more "authentic" with my own voice (which was also getting better)
  • So I recorded the narration using a lot of music software and hardware I have for other reasons (a (cheap) large area condenser microphone into Line 6 UX2 TonePort and GearBox to Ableton Live).
  • In Ableton Live I improved the sound using a multiband compression and noice gating.
  • Also in Ableton Live, I synchronized my voice to the Amy sound-track (in most cases I speak a little faster than Amy so things can be handled by increasing the pauses a bit).
  • Then back to Camtasia Studio adding my new sound track instead of Amy.
  • Final, procudtion made in Camtasia.
